[PATCH 0/7] arm64: dts: rockchip: Sound fixes and additions on RK3576 boards

Posted by Alexey Charkov 1 month, 1 week ago

Here are some device tree updates to improve sound output on RK3576
boards.

The first two patches fix analog audio output on FriendlyElec NanoPi M5,
as it doesn't work with the current device tree.

The third one is purely cosmetic, to present a more user-friendly sound
card name to the userspace on NanoPi M5.

The rest add new functionality: HDMI sound output on three boards that
didn't enable it, and analog sound on RK3576 EVB1.

Forgot to add, thankfully the fixes + enablement don't depend on each
other, so I've applied patches 1+2 to my fixes branch for 6.19
and the rest for 6.20.
