Is there an established way for me (from userspace) to pass the HDMI Channel Allocation (1 byte) to the driver? If not, can you recommend an approach?
In most of the drivers that I've inspected, the drivers seem to assume that there's a 1:1 mapping of Number-of-Channels to Channel-Allocation. However, the HDMI sink declares which speakers it has attached in the EDID. If I can match this in userspace... I need a way to communicate it to the driver.
