Revert "usb: dwc2: gadget: fix TX FIFO size and address initialization"

2016-10-18T11:21:40+00:00

This reverts commit aa381a7259c3 ("usb: dwc2: gadget: fix TX FIFO size
and address initialization").

The original commit removed the FIFO size programming per endpoint. The
DPTXFSIZn register is also used for DIEPTXFn and the SIZE field is r/w
in dedicated fifo mode. So it isn't appropriate to simply remove this
initialization as it might break existing behavior.

Also, some cores might not have enough fifo space to handle the
programming method used in the reverted patch, resulting in fifo
initialization failure.

Revert "usb: dwc2: gadget: change variable name to more meaningful"

2016-10-18T11:21:37+00:00

This reverts commit ba48eab8866c ("usb: dwc2: gadget: change variable
name to more meaningful").

This is needed to cleanly revert commit aa381a7259c3 ("usb: dwc2:
gadget: fix TX FIFO size and address initialization") which may cause
regressions on some platforms.

usb: dwc2: Add msleep for host-only

2016-10-17T09:30:29+00:00

Although a host-only controller should not have any associated delay,
some rockchip SOC platforms will not show the correct host-values of
registers until after a delay.

So add a 50 ms sleep when in host-only mode.

Pull ARM SoC late DT updates from Arnd Bergmann:
 "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"

usb: patches for v4.9 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.

usb: dwc2: Properly account for the force mode delays

2016-09-08T11:02:54+00:00

When a force mode bit is set and the IDDIG debounce filter is enabled,
there is a delay for the forced mode to take effect. This delay is due
to the IDDIG debounce filter and is variable depending on the platform's
PHY clock speed. To account for this delay we can poll for the expected
mode.

On a clear force mode, since we don't know what mode to poll for, delay
for a fixed 100 ms. This is the maximum delay based on the slowest PHY
clock speed.

usb: dwc2: Add delay to core soft reset

2016-09-08T11:02:52+00:00

Add a delay to the core soft reset function to account for the IDDIG
debounce filter.

If the current mode is host, either due to the force mode bit being
set (which persists after core reset) or the connector id pin, a core
soft reset will temporarily reset the mode to device and a delay from
the IDDIG debounce filter will occur before going back to host mode.
