Why are these marked as Volatile?
Can you provide some details on the issue that you are seeing?
--srini
Without volatile these registers are not reflecting in Hardware and
playback and capture is not working.
Will do recheck and keep only required registers as volatile.
This sounds like a total hack to me,
this might be happening in your case:
The default values for this register are different to actual defaults.
Ex: CDC_TX_TOP_CSR_SWR_AMIC0_CTL default is 0x00
so writing 0x0 to this register will be no-op as there is no change in
the register value as compared to default value as per regmap.
In you case make sure the hardware default values are correctly
reflected in tx_defaults array.
The default values in tx_defaults are proper. But same value is not
reflecting in Hardware, but In Cache it's reflecting set value.
Then setting the desired value should work.
