Add code to reset all reset signals as in usb DT node. A reset property
is an optional feature, so only print out a warning and do not fail if a
reset property is not present.

If a reset property is discovered, then use it to deassert, thus
bringing the IP out of reset.

0bc846a769 sunxi: A64: OHCI: prevent turning off shared USB clock
On the A64 the clock for the first USB controller is actually the parent
of the clock for the second controller, so turning them off in that order
makes the system hang.
Fix this by only turning off *both* clocks when the *last* OHCI controller
is brought down. This covers the case when only one controller is used.

9c22aec410 usb: sunxi: Use proper reg_mask for clock gate, reset
Masking clock gate, reset register bits based on the
probed controller is proper only due to the assumption
that masking should start with 0 even thought the controller
has separate PHY or shared between OTG.

unfortunately these are fixed due to lack of separate
clock, reset drivers.

Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG)
so we need to start reg_mask 0 - 2.

This patch calculated the mask, based on the register base
so that we can get the proper bits to set with respect to
probed controller.

We even do this masking by using PHY index specifier from dt,
but dev_read_addr_size is failing for 64-bit boards.

child node compatbile with 'rockchip,rk3399-usb3-phy' to retrieve the

base-address is never used.

eaaefb066c usb: xhci: Fix config fail of FS hub behind a HS hub with MTT
If a full speed hub connects to a high speed hub which supports MTT,
the MTT field of its slot context will be set to 1 when xHCI driver
setups an xHCI virtual device in xhci_setup_addressable_virt_dev().
Once usb core fetch its hub descriptor, and need to update the xHC's
internal data structures for the device, the HUB field of its slot
context will be set to 1 too, meanwhile MTT is also set before, this
will cause configure endpoint command fail. In the case, we should
clear MTT to 0 for full speed hub according to section 6.2.2.

This keeps in sync with Linux kernel commit:

793c819c6e usb: xhci: Set accurate add context flags when updating hub attributes
If a USB 3.0 hub is plugged into the root port of the xHC, the xHCI
driver will issue a 'Configure Endpoint' command to the xHC for it
to update its internal data structure for this hub device. The hub
attributes are in the slot context so we need tell xHC to update the
slot context by setting the add context flags of the input control
context to only cover the slot context.

At present the add context flags is or'ed with the slot context bit,
but it should really be accurately set to the slot context, as the
variable that holds the value of the add context flags comes from
whatever was set in the last command execution, which may contain
additional contexts that 'Configure Endpoint' command should not
touch. Some xHC implementations like x86 don't complain such, but
it was observed on Renesas RCar Gen3 platform that the RCar xHC
complains with a 'TRB error' completion codes as the response.

8c1de5e08b regmap: clean up regmap allocation
Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members.  There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".

As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.

Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

42637fdae8 usb: dwc2: Allow selection of data buffer size
If we use hardware with very small RAM (let's consider just a couple
of hundreds of kB but not megabytes) it is not super convenient to lose
64kB for statically allocated bufer which most probably won't be used
as big as it is. Typically we'll have much shorter data packages to
excahnge and in the worst case longer packets will be split on separate
transactions.

For those corner-cases user will be able to set his buffer size of
choice via USB_DWC2_BUFFER_SIZE option in menuconfig.

By default we'll use 64 kB as it was hard-coeded before so existing
users shouldn't be affected at all.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

d4efefe32e dm: usb: Fix broken usb_stop()
At present we only do device_remove() during usb stop. The DM API
device_remove() only marks the device state as inactivated, but
still keeps its USB topology (eg: parent, children, etc) in the DM
device structure. There is no issue if we only start USB subsystem
once and never stop it. But a big issue occurs when we do 'usb stop'
and 'usb start' multiple times.

Strange things may be observed with current implementation, like:
- the enumeration may report only 1 mass storage device is detected,
  but the total number of USB devices is correct.
- USB keyboard does not work anymore after a bunch of 'usb reset'
  even if 'usb tree' shows it is correctly identified.
- read/write flash drive via 'fatload usb' may complain "Bad device"

In fact, every time when USB host controller starts the enumeration
process, it takes random time for each USB port to show up online,
hence each USB device may appear in a different order from previous
enumeration, and gets assigned to a totally different USB address.
As a result, we end up using a stale USB topology in the DM device
structure which still reflects the previous enumeration result, and
it may create an exact same DM device name like generic_bus_0_dev_7
that is already in the DM device structure. And since the DM device
structure is there, there is no device_bind() call to bind driver to
the device during current enumeration process, eventually creating
an inconsistent software representation of the hardware topology, a
non-working USB subsystem.

The fix is to clear the unused USB topology in the usb_stop(), by
calling device_unbind() on each controller's root hub device, and
the unbinding will unbind all of its children automatically.

For Sandbox, we need scan the device tree each time when we start
the USB stack, in order to re-create the emulated USB devices and
bind drivers for them before we actually do the driver probe.

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.

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] .

78e3098752 usb: xhci: Enable TT to support LS/FS devices behind a HS hub
So far LS/FS devices directly attached to xHC root port can be
successfully enumerated by xHCI driver, but if they are connected
behind a hub, the enumeration process fails to address the device.

It turns out xHCI driver still misses a part that in the device's
input slot context, all Transaction Translator (TT) related fields
are not programmed. The xHCI spec defines how to enable TT.

Now LS/FS devices like USB keyboard/mouse can be enumerated behind
a high speed hub.

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.

This causes xHC on Intel platform does not respond the very first

from DTS. And add a comment for "hnp-srp-disable" property to
fully describe its effect.

We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 4xx,
so remove it.

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.
FWIW TravisCI builds everything with all 3 patches in place,
see https://travis-ci.org/abrodkin/u-boot/builds/239563813

will keep in otg mode and can't switch to host mode if not support
SNP/SRP capability. So add the property of "hnp-srp-disable" in the DTS
to config the contrller work in force mode of host.
