[PATCH v4 0/2] AM62: Add support for AM62 USB wrapper driver

From: Aswath Govindraju
Date: Thu Apr 14 2022 - 06:32:34 EST


The following series of patches add support for AM62 USB wrapper driver
and its corresponding bindings.

changes since v3:
- Removed the VBUS_VALID interrupt servicing as mode valid bit
need not be switched based on the connect/disconnect event.
The mode valid bit is being set during probe and cleared
during remove
- As VBUS_VALID interrupt is not being used, removed the interrupts
property from the bindings. As there is change in the dt-bindings
I did not pick the reviewed-by tags from the earlier version of
the series.

changes since v2:
- Removed the implementation of detecting the role from the wrapper
driver and moved the implementation to using linux,extcon-usb-gpio
driver for role detection.
- Updated the binding documentation and example to reflect the same.

changes since v1:
- Fixed the error with dev_pm_ops uninitialization, in patch 2.
This was reported by kernel test bot
- In patch 1, made correction in grammer of clocks property description
and added maxItems in the interrupts property based on comments
received from Roger
- In patch 1, corrected the title, fixed the description of
ti,syscon-phy-pll-refclk, added pattern properties and child node
in the example based on the comments from Krzysztof.
