In general Renesas SoC's SSI/SRC are all enabled, but some SoC is not.
H2 E2
SRC0 <=
SRC1 SRC1
SRC2 SRC2
... ...
Renesas Sound driver is assuming that *all* modules are
enabled, and thus it is using *data array* to access each modules.
Because of it, we have been using "status = disabled" at DT,
and using *full size* array but avoiding disabled module.
ex)
rcar_sound,src {
src-0 {
=> status = "disabled";
};
src1: src-1 {
...
};
...
But R-Car D3 have many disabled modules (It has SSI3/SSI4, SRC5/SRC6),
and Renesas SoC maintainer don't want above style on DT.
ex)
rcar_sound,src {
=> src0: src-0 { status = "disabled"; };
=> src1: src-1 { status = "disabled"; };
=> src2: src-2 { status = "disabled"; };
=> src3: src-3 { status = "disabled"; };
=> src4: src-4 { status = "disabled"; };
src5: src-5 {
...
};
src6: src-6 {
...
};
};
rcar_sound,ssi {
=> ssi0: ssi-0 { status = "disabled"; };
=> ssi1: ssi-1 { status = "disabled"; };
=> ssi2: ssi-2 { status = "disabled"; };
ssi3: ssi-3 {
...
};
ssi4: ssi-4 {
...
};
};
To adjust it, it needs to care about related for_each_child_of_node()
loop on rsnd driver, and it is used from...
> grep -l for_each_child_of_node sound/soc/sh/rcar/*
sound/soc/sh/rcar/core.c
sound/soc/sh/rcar/ctu.c
sound/soc/sh/rcar/dma.c
sound/soc/sh/rcar/dvc.c
sound/soc/sh/rcar/mix.c
sound/soc/sh/rcar/src.c
sound/soc/sh/rcar/ssi.c
sound/soc/sh/rcar/ssiu.c
This patch adjust to this situation.
By this patch, we can avoid disabled modules on DT
rcar_sound,src {
src5: src-5 {
...
};
src6: src-6 {
...
};
};
rcar_sound,ssi {
ssi3: ssi-3 {
...
};
ssi4: ssi-4 {
...
};
};
