Hi All,

V3 of this patch adding headphone jack detection support to the Anbernic RGnnXX series of handhelds. V3 corrects my misunderstanding of derivation of ALSA UCM file paths, and adds recieved Reviewed-by and Tested-by tags. Thanks to those that have reviewed and fed back on previous versions.

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
