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>;
|
||
|
|
};
