addresses, so we have a lot of u32 variables around, which are assigned

To allow compilation for 64-bit boards which use only memory below 4GB

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.

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.

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.

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).

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.

resulted on SoCFPGA (using the DWC2 driver) in some USB sticks not

This patch fixes situation when one would like to write large file into
medium with the file system (fat, ext4, etc).
This change sets file size limitation to the DFU internal buffer size.
Since u-boot is not supporting interrupts and seek on file systems, it
becomes challenging to store large file appropriately.
To reproduce this error - create large file (around 26 MiB) and sent it
to the target board.
Lets examine the flow of USB transactions:
0. DFU uses EP0 with 64B MPS [Max Packet Size]
1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions
2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent
from target board - IN transaction
(target->PC)
3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero
Length Packet]
Now the interesting part starts:
4. OUT (PC->target) Setup transaction (request to share DFU state)
5. IN (target->PC) - reply the current DFU state
- In the UDC driver the req->completion (with dfu_flush) is called
after successful IN transfer.
- The dfu_flush() (called from req->completion callback) saves the
whole file at once (u-boot doesn't support seek on fs).
Such operation takes considerable time. When the file
is large - e.g. 26MiB - this time may be more than 5 seconds.
6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush()
writes data to eMMC memory.
The dfu-util application has hard coded timeout on USB transaction
completion set to 5 seconds (it uses libusb calls).
When the file to store is large (e.g. 26 MiB) the time needed to write it
may excess the dfu-util timeout and following error message will be displayed:
"unable to read DFU status" on the HOST PC console.
This change is supposed to leverage DFU's part responsible for storing files
on file systems. Other DFU operations - i.e. raw/partition write to NAND and
eMMC should work as before.
The only functional change is the error reporting. When dfu_flush() fails
the u-boot prompt will exit with error information and dfu-util application
exits afterwards as well.

USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec,
8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT,
so these two should be kept separate. As EPs are either BULK or INTERRUPT
(or ISO), it is fine to have one array per direction for all transfer
types (also see e236519b73).
USB device address is 7 bits, so a bus may have more than 16 devices.
Check the device number, as the DWC2 driver only supports BULK/ISO for
the first 16 devices.

CSPLITs for INTERRUPT transactions have to be scheduled in each microframe
following the SSPLIT. INTERRUPT transfers are executed in the next even/
odd microframe depending on the HCCHAR_ODDFRM flag.
As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have
failed (transport error) without the error being detected by the host
driver. If the last CSPLIT is not received within 4 microframes after the
SSPLIT there was a transaction error and the complete transaction has
to be restarted.

Fix two errors in transfer len calculation, move loop invariant code out
of loop.
If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly
smaller), the xfer_len will be to large, e.g.:
xfer_len = MAX_TRANSFER_SIZE = 65535
max packet size = 512
=> num_packets = 128
=> IN xfer_len = 65536
For OUT transactions larger than (65536 - mps) bytes, the xfer_len
determination is quite awkward, it is only correct due to:
- max_packet_size for control/bulk/interrupt is required to be
power-of-two.
- (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero
for all allowed (2^3 ... 2^9) packet sizes
As the max xfer len is loop invariant, it can be moved out of the loop.

The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:
8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.
Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.
The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.

With the old order of initialization the hcor pointer has been setup to
