1Qualcomm SPMI arbiter/bus driver 2 3This is bus driver for Qualcomm chips that use SPMI to communicate with PMICs. 4 5Required properties: 6- compatible: "qcom,spmi-pmic-arb" 7- reg: Register block adresses and sizes for various parts of device: 8 1) PMIC arbiter channel mapping base (PMIC_ARB_REG_CHNLn) 9 2) SPMI write command (master) registers (PMIC_ARB_CORE_SW_DEC_CHANNELS) 10 3) SPMI read command (observer) registers (PMIC_ARB_CORE_REGISTERS_OBS) 11 12Optional properties (if not set by parent): 13- #address-cells: 0x1 - childs slave ID address 14- #size-cells: 0x1 15 16All PMICs should be placed as a child nodes of bus arbiter. 17Automatic detection of childs is currently not supported. 18 19Example: 20 21spmi@200f000 { 22 compatible = "qcom,spmi-pmic-arb"; 23 reg = <0x200f800 0x200 0x2400000 0x400000 0x2c00000 0x400000>; 24 #address-cells = <0x1>; 25 #size-cells = <0x1>; 26}; 27
