Add one optional property "rockchip,hdmi-codec" to let user specify HDMI device node in DTS so machine driver can find hdmi-codec device node for HDMI codec DAI. Use the presence of rockchip,audio-codec and rockchip,hdmi-codec to specify the use case. Use max98090 only : specify rockchip,audio-codec. Use HDMI only: specify rockchip,hdmi-codec. Use both max98090 and HDMI: specify rockchip,audio-codec and rockchip,hdmi-codec. Move these properties to optional because they are not needed for HDMI-only use case. "rockchip,audio-codec": The phandle of the MAX98090 audio codec "rockchip,headset-codec": The phandle of Ext chip for jack detection Signed-off-by: Cheng-Yi Chiang <cychiang@chromium.org> Link: https://lore.kernel.org/r/20191028071930.145899-3-cychiang@chromium.org Signed-off-by: Mark Brown <broonie@kernel.org>

Example:
|
|
|
|
/* For max98090-only board. */
|
|
sound {
|
|
