Motorola CPCAP PMIC device tree binding
Required properties:
- compatible : One or both of "motorola,cpcap" or "ste,6556002"
- reg : SPI chip select
- interrupt-parent : The parent interrupt controller
- 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
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;
};
};
