drivers/soundwire: Support Realtek ALC722 codec
This patch adds SoundWire driver to support ALC722 audio codec.
The existing ALC711 codec driver is refactored to include support for
ALC722 device based on config flag.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 0 and has strap
settings configuring it for unique ID 1:
chip drivers/soundwire/alc711
register "desc" = ""Headset Codec""
device generic 0.1 on end
end
reference datasheet: Realtek ALC722-CG ver. 0.56
TEST=This driver was tested on Intel RVP with on board ALC722 codec
by booting and disassembling the runtime SSDT to ensure that the
devices have the expected address and properties. Test soundcard
binding works and devices are detected and check for audio playback
using speaker output.
