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>;
spi-cs-high;
audio-codec {
#sound-dai-cells = <1>;
/* HiFi */
port@0 {
endpoint {
remote-endpoint = <&cpu_dai1>;
};
};
/* Voice */
port@1 {
endpoint {
remote-endpoint = <&cpu_dai2>;
};
};
};
};
};
