 "Here is the big USB and PHY driver pull request for 5.3-rc1.

  Lots of stuff here, all of which has been in linux-next for a while
  with no reported issues. Nothing is earth-shattering, just constant
  forward progress for more devices supported and cleanups and small
  fixes:

   - USB gadget driver updates and fixes

   - new USB gadget driver for some hardware, followed by a quick revert
     of those patches as they were not ready to be merged...

   - PHY driver updates

   - Lots of new driver additions and cleanups with a few fixes mixed
     in"

Pull device properties framework updates from Rafael Wysocki:
 "These add helpers for counting items in a property array and extend
  the "software nodes" support to be more convenient for representing
  device properties supplied by drivers and make the intel_cht_int33fe
  driver use that.

  Specifics:

   - Add helpers to count items in a property array (Andy Shevchenko).

   - Extend "software nodes" support to be more convenient for
     representing device properties supplied by drivers (Heikki
     Krogerus).

   - Add device_find_child_by_name() helper to the driver core (Heikki
     Krogerus).

   - Extend device connection code to also look for references provided
     via fwnode pointers (Heikki Krogerus).

   - Start to register proper struct device objects for USB Type-C muxes
     and orientation switches (Heikki Krogerus).

   - Update the intel_cht_int33fe driver to describe devices in a more
     general way with the help of "software nodes" (Heikki Krogerus)"

drivers/usb/typec/tps6598x.c: fix 4CC cmd write

2019-07-03T16:40:49+00:00

Writing 4CC commands with tps6598x_write_4cc() already has
a pointer arg, don't reference it when using as arg to
tps6598x_block_write(). Correcting this enforces the constness
of the pointer to propagate to tps6598x_block_write(), so add
the const qualifier there to avoid the warning.

Portinfo bit field is 3 bits wide, not 2 bits. This led to
a wrong driver configuration for some tps6598x configurations.

usb: typec: ucsi: ccg: add runtime pm workaround

2019-06-07T22:09:27+00:00

Cypress USB Type-C CCGx controller firmware version 3.1.10
(which is being used in many NVIDIA GPU cards) has known issue of
not triggering interrupt when a USB device is hot plugged to runtime
resume the controller. If any GPU card gets latest kernel with runtime
pm support but does not get latest fixed firmware then also it should
continue to work and therefore a workaround is required to check for
any connector change event.

The workaround is that i2c bus driver will call pm_request_resume()
to runtime resume ucsi_ccg driver. CCG driver will call the ISR
for any connector change event for NVIDIA GPU card and only if it has
old CCG firmware with the known issue.

usb: typec: ucsi: ccg: enable runtime pm support

2019-06-07T22:09:20+00:00

The change enables runtime pm support to UCSI CCG driver.
Added ucsi_resume() function to enable notification after
system reusme. Exported both ucsi_resume() and ucsi_send_command()
symbols in ucsi.c for modular build.
