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: |
|
|
|
- Documentation/devicetree/bindings/power/supply/cpcap-battery.yaml |
|
- Documentation/devicetree/bindings/power/supply/cpcap-charger.yaml |
|
- Documentation/devicetree/bindings/regulator/cpcap-regulator.txt |
|
- Documentation/devicetree/bindings/phy/phy-cpcap-usb.txt |
|
- Documentation/devicetree/bindings/input/cpcap-pwrbutton.txt |
|
- Documentation/devicetree/bindings/rtc/cpcap-rtc.txt |
|
- Documentation/devicetree/bindings/leds/leds-cpcap.txt |
|
- Documentation/devicetree/bindings/iio/adc/motorola,cpcap-adc.yaml |
|
|
|
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>; |
|
}; |
|
}; |
|
}; |
|
}; |
|
}; |
