[PATCH v1 1/2] ASoC: tac5xx2-sdw: update default regmap registers

[PATCH v1 1/2] ASoC: tac5xx2-sdw: update default regmap registers

[Niranjan H Y]

 At boot time, when the registers are accessed by asoc
layer while trying to enable a DAPM path, while the device
is still being attached, -EBUSY error will be thown by
regmap_read and regmap_udpate_bits. Because the regmap will
be in cache only mode. Add default values for these registers
so that, the cached values are returned instead of error.
Also drop the unwanted register writes with default values.

[PATCH v1 2/2] ASoC: sdw_utils: add spk component string for tac5xx2 family

[Niranjan H Y]

  The tac5xx2 RTD init does not populate card->components with the
spk:<prefix> string. With this change, "amixer -D hw:<card> info"
includes the spk identifier for each tac5xx2 speaker component,
following the same pattern used by other codec families.

  This allows userspace to identify the speaker codec at runtime
and enables UCM card matching for the tac5xx2 family.

Did you check the sorting of the table here?

The new macros use _CHANEL_VOLUME and _MASTER_GAIN, there's none using
_CHANNEL_GAIN?

See 0f60ecffbfe3 (ASoC: sdw_utils: generate combined spk components
string) for how other drivers do the same thing.

This was intentional to drop CHANNEL_GAIN as it is found to be not required for FU23.

I think I will add cleaner fix in next patch. What we need really are
#define TAC_SDCA_MASTER_GAIN	0x0B ( should be probably renamed to *_CHANNEL_GAIN )
#define TAC_SDCA_CHANNEL_VOLUME	0x02

And need to drop the duplicate macro 
#define TAC_SDCA_CHANNEL_GAIN	0x02
