Hi All, 

V2 of this patch adding support for headphone detection on the Anbernic RG35XX series. No functional changes on this revision, patches refactored to more clearly represent a single change per individual patch, remove vendor prefixing for the device tree binding, improve documentation of the DAPM widget changes and associated UCM, and small whitespace fixes.

Original message below:

This series adds the required device tree bindings to describe GPIOs for jack detection in the sun4i-codec driver, adds support for jack detection to the codec machine driver, and describes the hardware configuration in the RG35XX DTS. The existing speaker amplifier GPIO pin can then be used in concert with jack detection to enable userspace sound servers (via an ALSA UCM configuration) to disable the speaker route when headphones are connected.

Thanks to Chris Morgan for his assistance putting this series together.

Regards,

Ryan
