ASoC: pcm186x: Add initial PCM1862/63/64/65 universal ADC driver
This is an initial version of the PCM186x codec driver supporting both 2-channel and 4-channel device variants. Not all device features are supported yet such as master/slave mode PLL configuration for which the codec driver currently relies on the PCM186x built-in clock auto-detection feature or the connection of digital microphones. However here is what's here and what should work: - Support for SPI and I2C low-level interfaces - Regmap support and basic register definitions - Input Mixer and Mux selection - I2C, LJ, and TDM DAI format support Signed-off-by: Andreas Dannenberg <dannenberg@ti.com> Signed-off-by: Michael Stecklein <m-stecklein@ti.com> Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
