Re: [alsa-devel] [PATCH] [RFC] ARM: shmobile: bockw dts: Override #sound-dai-cells to zero

Hi

The default value of #sound-dai-cells in r8a7778.dtsi is one, while the /sound/simple-audio-card,cpu device node in r8a7778-bockw.dts uses a phandle without any extra cells ("<&rcar_sound>"), causing:

/sound/simple-audio-card,cpu: arguments longer than property
asoc-simple-card sound: parse error -22
asoc-simple-card: probe of sound failed with error -22

Override #sound-dai-cells to zero to fix this.

The rcar_sound node is still disabled. So why is this needed?!?

This error came from "simple-audio-card", not "rcar_sound" I think. # sound needs many drivers...

Actually, I don't want to have default #sound-dai-cells in r8a7778.dtsi. Like below. I will send this patch soon
