ASoC: dt-bindings: q6asm: Add Q6ASM_DAI_{TX_RX, TX, RX} defines
Right now the direction of a DAI has to be specified as a literal
number in the device tree, e.g.:
dai@0 {
reg = <0>;
direction = <2>;
};
but this does not make it immediately clear that this is a
playback/RX-only DAI.
Actually, q6asm-dai.c has useful defines for this. Move them to the
dt-bindings header to allow using them in the dts(i) files.
The example above then becomes:
dai@0 {
reg = <0>;
direction = <Q6ASM_DAI_RX>;
};
which is immediately recognizable as playback/RX-only DAI.
