848436a48d usb: emul: Expose find_descriptor() as a public API
This can be useful outside of the sandbox usb emulation uclass
driver. Expose it as a public API with a proper prefix (usb_emul_).

84aa8536f0 usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()
Current emulator select logic in usb_emul_find_devnum() is to test
the USB address. The USB address of the device being enumerated is
initialized to zero at the beginning of the enumeration process in
usb_setup_device(). At this point, the saved USB address in the
platform data has not been assigned to any valid USB address either.
This means: the logic will select an emulator device according to
its sequence of declaring order in the device tree. Take test.dts
for example, flash-stick@0 will be selected before flash-stick@1.
But unfortunately such logic is wrong.

In fact USB devices show up in a random order during the enumeration
which means usb_emul_find_devnum() may be called on port 3 for keyb@3
before on port 0 for flash-stick@0.

To fix this, we introduce a new emulator uclass specific platdata
to store the USB device's port number on its parent hub, and update
the logic to test the port number instead.

022ceacaf8 dm: usb: xhci: Implement get_max_xfer_size() operation
xHCD allocates one segment which includes 64 TRBs for each endpoint
and the last TRB in this segment is configured as a link TRB to form
a TRB ring. Each TRB can transfer up to 64K bytes, however data
buffers referenced by transfer TRBs shall not span 64KB boundaries.
Hence the maximum number of TRBs we can use in one transfer is 62.

7489d22a3c usb: xhci: Set number of event segments and entries to 1
The Linux kernel driver sets the number of event segments and entries
to 1 , while the initial import of the xhci code set that values to 3
for reasons unknown. While most controllers are fine with more event
segments with more entries, there are standard-conformant controllers
(ie. Renesas RCar xHCI) which only support 1 event segment.

Set the number of event segments and event entries back to 1 to allow
such controllers to work with U-Boot xHCI stack. Note that the Renesas
controller correctly indicates ERST Max = 1 in HCSPARAMS2[7:4] .

de4e4edaff usb: gadget: g_dnl: Sync internal SN variable with env
Since commit 842778a091 ("usb: gadget: g_dnl: only set iSerialNumber

serial number for TI boards, showing this line instead:

    ????????????	fastboot

This is because serial# env variable could be set after g_dnl gadget was
initialized (e.g. by using env_set() in the board file).

To fix this, let's update internal serial number variable (g_dnl_serial)
when "serial#" env var is changed.

are not programmed. The xHCI spec defines how to enable TT.

Now LS/FS devices like USB keyboard/mouse can be enumerated behind

493b8dd070 usb: xhci: Program 'route string' in the input slot context
xHCI spec says: the values of the 'route string' field shall be
initialized by the first 'Address Device' command issued to a
device slot, and shall not be modified by any other command.

So far U-Boot does not program this field, and it does not prevent
SS device directly attached to root port, or HS device behind an HS
hub, from working, due to the fact that 'route string' is used by
the xHC to target SS packets. But in order to enumerate devices
behind an SS hub, this field must be programmed.

With this commit and along with previous commits, now SS & HS devices
attached to a USB 3.0 hub can be enumerated by U-Boot.

As usual, this new feature is only available when DM is on.

f342119602 usb: hub: Send correct wValue to get hub descriptor of a USB 3.0 hub
Testing a USB 3.0 hub by connecting it to the xHCI port on Intel
MinnowMax, when issuing 'get hub descriptor' to the hub, xHCI
reports a transfer event TRB with a completion code 6 which means
'Stall Error'.

In fact super speed USB hub descriptor type is 0x2a, not 0x29.
Sending correct SETUP packet to the hub makes it not stall anymore.

aab0db08c0 usb: xhci: Add input slot context in xhci_set_configuration()
A valid input slot context for a 'configure endpoint' command requires
the 'Context Entries' field to be initialized to the index of the last
valid endpoint context that is defined by the target configuration. We
set up the 'Context Entries' field, but we forget to include the input
slot context in the input control context 'Add Context flags' bitmap.
So xHC will simply ignore input slot context and continue using its own
which contains old information of the device.

209b98de01 usb: xhci: Initialize scratchpad buffer array and scratchpad buffers
The scratchpad buffer array is used to define the locations of
statically allocated memory pages that are available for the
private use of the xHC. The xHCI spec explicitly mentions that
system software shall allocate the scratchpad buffers before
placing the xHC in to Run mode (Run/Stop (R/S) = ‘1’), however
U-Boot is missing this part.

This causes xHC on Intel platform does not respond the very first
'enable slot' command that is given to xHC and the 'enable slot'
command completion event TRB is never generated and xHC seems to
hang forever.

However, on some platforms (e.g. Siemens) the serial number is set at

serial (since it is not set).

This commit moves the g_dnl_bind_fixup() call before the g_dnl_serial

9000eddbae drivers/usb/ehci: Use platform-specific accessors
Current implementation doesn't allow utilization of platform-specific
reads and writes.

But some arches or platforms may want to use their accessors that do
some extra work like adding barriers for data serialization etc.

Interesting enough OHCI accessors already do that so just aligning
EHCI to it now.

This is a resend of http://patchwork.ozlabs.org/patch/726714/
Back in the day this patch broke some PPC and Sandbox boards
as they we missing inclusion of "asm/io.h". Those missing items were
fixed with:
 1) http://patchwork.ozlabs.org/patch/751397/
 2) http://patchwork.ozlabs.org/patch/771099/

So now it should be safe to apply this patch.

In the end we will have:

   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

From: Nicolas Le Bayon <nicolas.le.bayon@st.com>

Instead of using a fixed-size array to store variable name, preferring a dynamic allocation treats correctly all variable name lengths.
Variable names are growing through releases and features. By this way, name clipping is prevented.

889239d6b5 usb: dwc3: gadget: make cache-maintenance on event buffers more robust
Merely using dma_alloc_coherent does not ensure that there is no stale
data left in the caches for the allocated DMA buffer (i.e. that the
affected cacheline may still be dirty).

The original code was doing the following (on AArch64, which
translates a 'flush' into a 'clean + invalidate'):
  # during initialisation:
      1. allocate buffers via memalign
      	 => buffers may still be modified (cached, dirty)
  # during interrupt processing
      2. clean + invalidate buffers
      	 => may commit stale data from a modified cacheline
      3. read from buffers

This could lead to garbage info being written to buffers before
reading them during even-processing.

To make the event processing more robust, we use the following sequence
for the cache-maintenance:
  # during initialisation:
      1. allocate buffers via memalign
      2. clean + invalidate buffers
      	 (we only need the 'invalidate' part, but dwc3_flush_cache()
	  always performs a 'clean + invalidate')
  # during interrupt processing
      3. read the buffers
      	 (we know these lines are not cached, due to the previous
	  invalidation and no other code touching them in-between)
      4. clean + invalidate buffers
      	 => writes back any modification we may have made during event
	    processing and ensures that the lines are not in the cache
	    the next time we enter interrupt processing

Note that with the original sequence, we observe reproducible
(depending on the cache state: i.e. running dhcp/usb start before will
upset caches to get us around this) issues in the event processing (a
fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the
first time interrupt handling is invoked) when running USB mass
storage emulation on our RK3399-Q7 with data-caches on.

The dwc3_flush_cache() call was declared and used inconsistently:
 * The declaration assumed 'int' for addresses (a potential issue
   when running in a LP64 memory model).
 * The invocation cast the address to 'long'.

This change ensures that both the declaration and usage of this
function consistently uses 'uintptr_t' for correct behaviour even
when the allocated buffers (to be flushed) reside outside of the
lower 32bits of memory.

7b82a229e5 sunxi: prepare for sharing MACH_SUN8I_H3 config symbol
The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

57faca19a8 drivers: USB: OHCI: allow compilation for 64-bit targets
OHCI has a known limitation of allowing only 32-bit DMA buffer
addresses, so we have a lot of u32 variables around, which are assigned
to pointers and vice versa. This obviously creates issues with 64-bit
systems, so the compiler complains here and there.
To allow compilation for 64-bit boards which use only memory below 4GB
anyway (and to avoid more invasive fixes), adjust some casts and types
and assume that the EDs and TDs are all located in the lower 4GB.
This fixes compilation of the OHCI driver for the Pine64.

eth-uclass.c expects DM-capable Ethernet adapters to implement ops->
read_rom_hwaddr(), or for some other mechanism to set pdata->enetaddr, or
for the user to set environment variable $usbethaddr. Without any of
these, it will refuse to initialize the device since no valid MAC address
is known. Implement this function for the smsc95xx driver.

With this feature implemented, there is no point smsc95xx_init_common()
re-reading the MAC address from ROM, so ifdef out this code when DM_ETH
is enabled.

This allows (at least) the built-in Ethernet on the NVIDIA Harmony board

cea6c8ce23 net: asix: Fix ASIX 88772B with driver model
Commit 147271209a ("net: asix: fix operation without eeprom")
added a special handling for ASIX 88772B that enable another
type of header. This break the driver in DM mode as the extra handling
needed in the receive path is missing.

However this new header mode is not required and only seems to
increase the code complexity, so this patch revert this part of
commit 147271209a.

This also reverts commit 41d1258ace

2f6a7e8ce5 ARM: tegra: fix USB ULPI PHY reset signal inversion confusion
USB ULPI PHY reset signals are typically active low. Consequently, they
should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in
the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use.
However, in DT properties that U-Boot does use, the value has been set to
0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot.

This change fixes the DT to correctly represent the HW, and fixes the
Tegra USB driver to cope with the fact that dm_gpio_set_value() internally
handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

7c22e26ec5 sunxi: musb: Re-init musb controller on repeated probe calls
With sunxi-musb musb_lowlevel_init() can fail when a charger; or no cable
is plugged into the otg port.

To avoid leaking the struct musb allocated by musb_init_controller()
on repeated musb_usb_probe() calls, we were caching its result.
But musb_init_controller() does more, such as calling sunxi_musb_init()
which enables the clocks.

Not calling sunxi_musb_init() causes the musb controller to stop working
after a "usb reset" since that calls musb_usb_remove() which disables the
clocks.

This commit fixes this by removing the caching of the struct returned
from musb_init_controller(), it replaces this by free-ing the allocated
memory in musb_usb_remove() and calling musb_usb_remove() on
musb_usb_probe() errors to ensure proper cleanup.

While at it also make musb_usb_probe() and musb_usb_remove() static.

was not functioning correctly (EHCI timeouts).

This patch brings the two-byte shift to the DriverModel implementation

2b58e1b76d usb: add (move) CONFIG_USB_HOST to Kconfig
The meaning of CONFIG_USB in U-Boot is different from that in Linux.

As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the
USB host controller support, while CONFIG_USB_SUPPORT is used to
enable the whole of the USB sub-system.

When I added CONFIG_USB into Kconfig by commit 6e7e9294d3 ("usb:
add basic USB configs in Kconfig"), I planned to follow the Linux's
convention, i.e. CONFIG_USB to enable/disable the USB host support.

Then, commit 68f7c5db2d ("usb: Generic USB Kconfig option, that
fits both host and gadget and comments") changed the logic of the
CONFIG_USB to point to the whole of the USB sub-system.  As a result,
currently we do not have an option for USB host.

This commit adds CONFIG_USB_HOST, which will be useful to compile
in the USB host support code.

CONFIG_USB_HOST is not referenced at all, but strangely some boards
define it in board headers.  I removed them because USB_HOST will be
selected in Kconfig going forward.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

1e6fb0e367 usb: ehci: only shutdown opened controller
If the usb controller is not running, no need to shutdown it,
otherwise `usb stop` complains about:
"EHCI failed to shut down host controller".

To i.MX7D SDB, there are two usb ports, one Host, one OTG.
If we only plug one udisk to the Host port and then `usb start`,
the OTG controller for OTG port does not run actually. Then,
if `usb stop`, the OTG controller for OTG port will also be
shutdown, but it is not running.

This patch adds a check to only shutdown the running controller.

Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it
into CONFIG_USB_XHCI_HCD.

As commented in the help of "config USB_XHCI" entry, this has been
a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI
have been unified in favor of the former.

Note:
Some boards define CONFIG_USB_XHCI in their headers without
CONFIG_USB, which does not meet the "depends on" in Kconfig.
I added CONFIG_USB=y for those boards when converting.
Otherwise, they would fail to build.

2bf352f0c1 usb: dwc2: Add delay to fix the USB detection problem on SoCFPGA
With patch c998da0d (usb: Change power-on / scanning timeout handling),
the USB scanning is started earlier and with a smaller timeout. This
resulted on SoCFPGA (using the DWC2 driver) in some USB sticks not
getting detected any more. This patch now adds a 1 second delay (in
the host mode only) to the DWC2 driver before the scanning is started.
With this delay, now all problematic USB keys are detected successfully
again. And there is no need any more to change the delay / timeout
in the common USB code (usb_hub.c).

Before this commit we were also disabling the companion clk-gate /

This commit fixes crash on BananaPi (and possibly others)
casued by 3f9f8a5b83.

Crash reason:
When no ops were passed to ehci_register(), USB host driver caused
NULL pointer dereference.

Most of ehci-fsl header describe USB controller

This patch renames it to a generic header: ehci-ci.h
Contents of file are not changed (so it contains several

d3d844f84a usb: ulpi: Fix compile warning in read/write on 64-bit machines.
ulpi_read and ulpi_write are used to read/write registers via ULPI bus.
Code generates compilation warnings on 64-bit machines where pointer
is cast to u32.

This patch drops all but last 8 bits of register address.
It is possible, because addresses on ULPI bus are 6- or 8-bit.

It is not possible (according to ULPI 1.1 spec) to have more
than 8-bit addressing.

This patch should not cause regressions as all calls to
ulpi_read/write use either structure pointer (@ address 0) or integer
offsets cast to pointer - addresses requested are way below 8-bit range.

e320f0bc9b smsc95xx: fix operation on 64-bit systems
smsc95xx_read_reg() should calculate sizeof(*data) not sizeof(data) since
data is a pointer, and the value pointed at is being transferred over USB,
not the value of the pointer. This fixes operation of the driver in 64-bit
builds, such as the Raspberry Pi 3.

74322201dd fastboot: allow retrieving fastboot variables from env
Some boards need to expose device specific variable through fastboot
(to adpat the flashing script depending on hardware revision for
example).

Provide a way to expose custom fastboot variables. Note that all
variables meant to be exposed through fastboot should be be prefixed
with 'fastboot.', the variable should not exceed 32 bytes (including
the prefix and the trailing '\0') and the variable content should
fit in the response buffer (60 bytes excluding the 'OKAY' prefix and
the trailing '\0').

f9d0fd8a56 usb: gadget: Move CONFIG_USB_GADGET to Kconfig
The description was borrowed from kernel. "tristate" type was changed
to "bool" (I believe we don't support modules for u-boot yet, right?).
CONFIG_USB_GADGET requires CONFIG_USB to be defined too, so add it along
as well.

Definitions were added to defconfig files in a way that
"make savedefconfig" generates exactly the same file as used defconfig.
