PCM512x audio CODECs
These devices support both I2C and SPI (configured with pin strapping
on the board).
Required properties:
- compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141" or
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
- AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
device, as covered in bindings/regulator/regulator.txt
Optional properties:
- clocks : A clock specifier for the clock connected as SCLK. If this
is absent the device will be configured to clock from BCLK. If pll-in
and pll-out are specified in addition to a clock, the device is
configured to accept clock input on a specified gpio pin.
- pll-in, pll-out : gpio pins used to connect the pll using <1>
through <6>. The device will be configured for clock input on the
given pll-in pin and PLL output on the given pll-out pin. An
external connection from the pll-out pin to the SCLK pin is assumed.
