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.
