[PATCH v1 04/10] ASoC: codecs: wsa881x: split into common and soundwire drivers

Alexey Klimov
2024-11-01T05:32:04Z

This is required in order to introduce wsa881x driver that works
in analog mode and is configurable via i2c only.
Functional changes, if any, are kept to be minimal and common
parts or parts that can be shared are moved into wsa881x-common
helper driver.
The regmap config structure now contains 0x3000 offset as required
by soundwire spec.

While at this, also fix the typo in WSA881X_ADC_EN_SEL_IBIAS
register name and rename wsa881x_set_sdw_stream() to
wsa881x_set_stream().
