CS53L30 is a Quad-Channel ADC from Cirrus Logic with an I2S/TDM DAI. So this patch adds support for CS53L30 that supports 24-bit recording feature.
Signed-off-by: Nicolin Chen nicoleotsuka@gmail.com
Changelog: v5->v6
- Added clock controls
- Reconstructed bitfield macros and improved coding style
- Fixed some misuses of regmap_update_bits()
- Added TLV volume controls to replace enums for preamplifier
- Added micbias level in DT instead of exposing to user-space
- Simplified SDOUTx controls by removing cs53l30_asp_sdout_event() (Still be able to use set_tristate() instead)
- Removed useless header files and sort the rest alphabetically
- Registered runtime pm functions to the driver
- Added regulator controls (VA and VP)
- Added writeable register function for regmap
- Merged two ASP dais
- Added TDM support
- Added a simple introduction in commit log

the hardware design connects both SDOUT1 and SDOUT2pins to output data. Otherwise, it indicates thatonly SDOUT1 is connected for data output.* CS53l30 supports 4-channel data output in the same* frame using two different ways:* 1) Normal I2S mode on two data pins -- each SDOUT* carries 2-channel data in the same time.* 2) TDM mode on one signle data pin -- SDOUT1 carries* 4-channel data per frame.+Example:
+codec: cs53l30@48 {
compatible = "cirrus,cs53l30";reg = <0x48>;reset-gpios = <&gpio 54 0>;+};
