ae4d814bf1 usb: patches for v4.10 merge window
One big merge this time with a total of 166 non-merge commits.
 
 Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
 second (22.5%). The remaining 9.3% are scattered on gadget drivers.
 
 The most important changes for dwc2 are the peripheral side DMA support
 implemented by Synopsys folks and support for the new IOT dwc2
 compatible core from Synopsys.
 
 In dwc3 land we have support for high-bandwidth, high-speed isochronous
 endpoints and some non-critical fixes for large scatter lists.
 
 Apart from these, we have our usual set of cleanups, non-critical fixes,
 etc.

3922fb46f0 usb: dwc2: add amcc,dwc-otg support
This patch adds support for the "amcc,usb-otg" device
which is found in the PowerPC Canyonlands' dts.

The device definition was added by:

commit c89b3458d8 ("powerpc/44x: Add USB DWC DTS entry to Canyonlands
board")

but without any driver support as the dwc2 driver wasn't available at
that time.

Note: The system can't use the generic "snps,dwc2" compatible
because of the special ahbcfg configuration. The default
GAHBCFG_HBSTLEN_INCR4 of snps,dwc2 can cause a system hang
when the USB and SATA is used concurrently.

3f1dae6b19 usb: host: xhci: plat: add support for Renesas r8a7796 SoC
This patch adds support for Renesas r8a7796 SoC. This SoC is not
compatible with r8a7795 because using firmware version differs.

Since the "V2" firmware can be used on both r8a7795 (es1.x) and r8a7796,
the "renesas,rcar-gen3-xhci" keeps to use the "V2" for now.

Some resources, such as IPPC register etc, shared with device
driver are moved into common glue layer when xHCI driver is the
host side of dual-role mode and they should be changed as optional
properties if they are required ones before. For clarity, add
a new part of binding to support host side of dual-role mode.

This binding was deprecated due to commit aa381a7259 ("usb: dwc2:
gadget: fix TX FIFO size and address initialization"). However that
commit is now reverted, so also revert this commit.

The binding is valid and shouldn't be deprecated.

c913fc4146 ARM: SoC: late DT updates for v4.9
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

This time around we have 92 non-merge commits. Most
 of the changes are in drivers/usb/gadget (40.3%)
 with drivers/usb/gadget/function being the most
 active directory (27.2%).
 
 As for UDC drivers, only dwc3 (26.5%) and dwc2
 (12.7%) have really been active.
 
 The most important changes for dwc3 are better
 support for scatterlist and, again, throughput
 improvements. While on dwc2 got some minor stability
 fixes related to soft reset and FIFO usage.
 
 Felipe Tonello has done some good work fixing up our
 f_midi gadget and Tal Shorer has implemented a nice
 API change for our ULPI bus.
 
 Apart from these, we have our usual set of
 non-critical fixes, spelling fixes, build warning
 fixes, etc.

This is a minimal driver to support bringing a usb4604 device
from microchip out of reset and into hub mode. The usb4604 device
is related to the usb3503 device, but it didn't seem close enough

some of the usb3503 structure and trims it down to just handle
the optional reset gpio and adds the i2c command to put the
device into hub mode.

to this the phy-names with the suffix 'utmi' are also not valid and
should have the suffix 'usb2'. Correct both the XUSB pad controller pad

4a5219edcd ARM: SoC driver updates for v4.7
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons. For the most part, this is now related to power management
 controllers, which have not yet been abstracted into a separate
 subsystem, and typically require some code in drivers/soc or arch/arm
 to control the power domains.
 
 Another large chunk here is a rework of the NVIDIA Tegra USB3.0
 support, which was surprisingly tricky and took a long time to
 get done.
 
 Finally, reset controller handling as always gets merged through here
 as well.

bc5081617f usb: dwc3: drop FIFO resizing logic
That FIFO resizing logic was added to support OMAP5
ES1.0 which had a bogus default FIFO size. I can't
remember the exact size of default FIFO, but it was
less than one bulk superspeed packet (<1024) which
would prevent USB3 from ever working on OMAP5 ES1.0.

However, OMAP5 ES1.0 support has been dropped by
commit aa2f4b16f8 ("ARM: OMAP5: id: Remove ES1.0
support") which renders FIFO resizing unnecessary.

69bec72598 USB: core: let USB device know device node
Although most of USB devices are hot-plug's, there are still some devices
are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
If these kinds of USB devices are multiple functions, and they can supply
other interfaces like i2c, gpios for other devices, we may need to
describe these at device tree.

In this commit, it uses "reg" in dts as physical port number to match
the phyiscal port number decided by USB core, if they are the same,
then the device node is for the device we are creating for USB core.

4670ba6c9e doc: usb: ci-hdrc-usb2: add property non-zero-ttctrl-ttha
If this property is not set, the max packet size is 1023 bytes, and if
the total of packet size for pervious transactions are more than 256 bytes,
it can't accept any transactions within this frame. The use case is single
transaction, but higher frame rate.

If this property is set, the max packet size is 188 bytes, it can handle
more transactions than above case, it can accept transactions until it
considers the left room size within frame is less than 188 bytes, software
needs to make sure it does not send more than 90%
maximum_periodic_data_per_frame. The use case is multiple transactions, but
less frame rate.

87cf5586fd usb: patches for v4.5
A ton of improvements to dwc2 have been made. The
 driver should be a lot more stable on v4.5 then ever
 before.
 
 Our good old dwc3 got a few cleanups and misc fixes
 and also added support to Xilinx's integration of
 this IP.
 
 Yoshihiro Shimoda gives us support for a new USB3
 peripheral controller from Renesas.
 
 Other than these, the usual misc fixes all over the
 place.

746bfe63bb usb: gadget: renesas_usb3: add support for Renesas USB3.0 peripheral controller
R-Car H3 has USB3.0 peripheral controllers. This controller's has the
following features:
 - Supports super, high and full speed
 - Contains 30 pipes for bulk or interrupt transfer
 - Contains dedicated DMA controller

This driver doesn't support the dedicated DMAC for now.

d0450272a6 usb: renesas_usbhs: add device tree support for r8a779[23]
Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.
