Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.
Ok I will check this.
This patch introduces to the binding the standard property #sound-dai-cells
and also an optional codec child node to hold codec specific properties.
Currently there is only one property in this node however the downstream
driver shows a number of other properties that are supported by the codec
hardware, that could be implemented in the future. This maintains the
existing driver ABI and keeps consistency with the rk817 bindings.
So you are adding a new node? Just for one property? No, just put it
into parent node.
The existing upstream codec driver parses the property from the "codec"
sub-node, if I
move it to the parent node here, I will need to patch the codec driver
to search in both locations,
so as to not break the rk817 bindings. If that is preferred, I can do
it that way.
Downstream driver does not matter at all in that aspect.
The codec hardware supports additional properties but they are not
implemented currently in
upstream driver.

Krzysztof
