Motorola CPCAP PMIC device tree binding
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : One or both of "motorola,cpcap" or "ste,6556002"
|
||
|
|
- reg : SPI chip select
|
||
|
|
- interrupts : The interrupt line the device is connected to
|
||
|
|
- interrupt-controller : Marks the device node as an interrupt controller
|
||
|
|
- #interrupt-cells : The number of cells to describe an IRQ, should be 2
|
||
|
|
- #address-cells : Child device offset number of cells, should be 1
|
||
|
|
- #size-cells : Child device size number of cells, should be 0
|
||
|
|
- spi-max-frequency : Typically set to 3000000
|
||
|
|
- spi-cs-high : SPI chip select direction
|
||
|
|
|
||
|
|
Optional subnodes:
|
||
|
|
|
||
|
|
The sub-functions of CPCAP get their own node with their own compatible values,
|
||
|
|
which are described in the following files:
|
||
|
|
|
||
|
|
- ../power/supply/cpcap-battery.txt
|
||
|
|
- ../power/supply/cpcap-charger.txt
|
||
|
|
- ../regulator/cpcap-regulator.txt
|
||
|
|
- ../phy/phy-cpcap-usb.txt
|
||
|
|
- ../input/cpcap-pwrbutton.txt
|
||
|
|
- ../rtc/cpcap-rtc.txt
|
||
|
|
- ../leds/leds-cpcap.txt
|
||
|
|
- ../iio/adc/cpcap-adc.txt
|
||
|
|
|
||
|
|
The only exception is the audio codec. Instead of a compatible value its
|
||
|
|
node must be named "audio-codec".
|
||
|
|
|
||
|
|
Required properties for the audio-codec subnode:
|
||
|
|
|
||
|
|
- #sound-dai-cells = <1>;
|
||
|
|
|
||
|
|
The audio-codec provides two DAIs. The first one is connected to the
|
||
|
|
Stereo HiFi DAC and the second one is connected to the Voice DAC.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
&mcspi1 {
|
||
|
|
cpcap: pmic@0 {
|
||
|
|
compatible = "motorola,cpcap", "ste,6556002";
|
||
|
|
reg = <0>; /* cs0 */
|
||
|
|
interrupt-parent = <&gpio1>;
|
||
|
|
interrupts = <7 IRQ_TYPE_EDGE_RISING>;
|
||
|
|
interrupt-controller;
|
||
|
|
#interrupt-cells = <2>;
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
spi-max-frequency = <3000000>;
|
