- Qualcomm SPMI arbiter/bus driver
- This is bus driver for Qualcomm chips that use SPMI to communicate with PMICs.
- Required properties:
- - compatible: "qcom,spmi-pmic-arb"
- - reg: Register block adresses and sizes for various parts of device:
- 1) PMIC arbiter channel mapping base (PMIC_ARB_REG_CHNLn)
- 2) SPMI write command (master) registers (PMIC_ARB_CORE_SW_DEC_CHANNELS)
- 3) SPMI read command (observer) registers (PMIC_ARB_CORE_REGISTERS_OBS)
- Optional properties (if not set by parent):
- - #address-cells: 0x1 - childs slave ID address
- - #size-cells: 0x1
- All PMICs should be placed as a child nodes of bus arbiter.
- Automatic detection of childs is currently not supported.
- Example:
- spmi@200f000 {
- compatible = "qcom,spmi-pmic-arb";
- reg = <0x200f800 0x200 0x2400000 0x400000 0x2c00000 0x400000>;
- #address-cells = <0x1>;
- #size-cells = <0x1>;
- };
