This series adds basic support for LPCM audio over HDMI interfaces
to the Khadas VIM3L (reusing the same config as the VIM3) and the
HardKernel ODROID-C4 devices. I'm sure support can be extended to
include other hardware but this gets the HDMI port working as a
minimum capability. I have personally tested with both devices.
