[PATCH v8 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case
Cheng-Yi Chiang
cychiang at chromium.org
Fri Oct 25 13:30:04 UTC 2019
Support three different use cases with rockchip_max98090 driver:
- max98090 only: Current usage, where HDMI link is missing.
- HDMI only: Needed use case for veyron_mickey board.
- max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.
Note that we keep max98090 only usage for backward compatibility.
>From devicetree, different compatible string can be passed to configure
the usage.
Signed-off-by: Cheng-Yi Chiang <cychiang at chromium.org>

The checkpatch error
"Macros with complex values should be enclosed in parentheses"
seems not suitable for the macro usage for DAPM widget, route, and controls.
