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.

ASoC: Replace HTTP links with HTTPS ones Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

ASoC: pcm186x: Fix device reset-registers trigger value According to the current device datasheet (TI Lit # SLAS831D, revised March 2018) the value written to the device's PAGE register to trigger a complete register reset should be 0xfe, not 0xff. So go ahead and update to the correct value.
