Hello,
This patch series adds support for S/PDIF receiver found on RK3308.
The code is based on Rockchip Kernel 4.4. Several ALSA controls such as synchronization status, sample rate and channel status bits are added. Also some basic error handling such as parity error or BMC decode error are performed. The implementation took stm32-spdifrx and mchp-spdifrx as reference.
The driver is tested to be working on my custom board based on Firefly CORE-3308Y, with a TOSLINK receiver.
This is my first time submitting a new driver to kernel, so I'll appreciate it if I can be corrected for anything wrong.
