It's on one PMIC bus mapped by regmap-spi. Will add the PMIC part in
next version:
sc2731_pmic: pmic@0 {
compatible = "sprd,sc2731";
reg = <0>;
spi-max-frequency = <26000000>;
interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
interrupt-controller;
#interrupt-cells = <2>;
#address-cells = <1>;
#size-cells = <0>;
vibrator@eb4 {
compatible = "sprd,sc27xx-vibrator";
reg = <0xeb4>;
};
};
Is that OK for you? Thanks.
