| 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>; |
| }; |
