+These devices support both I2C and SPI (configured with pin strapping +on the board).
+Required properties:
- compatible : "wlf,wm8985" or "wlf,wm8758"
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
+Pins on the device for linking into audio routes:
- LIN : left microphone pre-amp negative input
- LIP : left microphone pre-amp positive input
- RIN : right microphone pre-amp negative input
- RIP : right microphone pre-amp positive input
- L2 : left line input / secondary pre-amp positive input
- R2 : right line input / secondary pre-amp positive input
- AUXL : left auxiliary input (WM8985 only)
- AUXR : right auxiliary input (WM8985 only)
- HPL : left headphone / line output (the LOUT1 pin)
- HPR : right headphone / line output (the ROUT1 pin)
- SPKL : left headphone / line output (the LOUT2 pin)
- SPKR : right headphone / line output (the ROUT2 pin)
- Mic Bias : microphone bias
+Example:
+wm8758: audio-codec@1a {
- compatible = "wlf,wm8758";
- reg = <0x1a>;
+};
You should probably mention the regulators as well.
Thanks, Charles
