PCM512x and TAS575x audio CODECs/amplifiers
2
-
3
-
These devices support both I2C and SPI (configured with pin strapping
4
-
on the board). The TAS575x devices only support I2C.
5
-
6
-
Required properties:
7
-
8
-
- compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141",
9
-
"ti,pcm5142", "ti,pcm5242", "ti,tas5754" or "ti,tas5756"
10
-
11
-
- reg : the I2C address of the device for I2C, the chip select
12
-
number for SPI.
13
-
14
-
- AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
15
-
device, as covered in bindings/regulator/regulator.txt
16
-
17
-
Optional properties:
18
-
19
-
- clocks : A clock specifier for the clock connected as SCLK. If this
20
-
is absent the device will be configured to clock from BCLK. If pll-in
21
-
and pll-out are specified in addition to a clock, the device is
22
-
configured to accept clock input on a specified gpio pin.
23
-
24
-
- pll-in, pll-out : gpio pins used to connect the pll using <1>
25
-
through <6>. The device will be configured for clock input on the
26
-
given pll-in pin and PLL output on the given pll-out pin. An
27
-
external connection from the pll-out pin to the SCLK pin is assumed.
28
-
Caution: the TAS-desvices only support gpios 1,2 and 3
29
