Driver for part of pm8916 PMIC - gpio and power/reset keys
|
|
|
|
This device should be child of SPMI pmic.
|
|
|
|
1) GPIO driver
|
|
|
|
Required properties:
|
|
- compatible: "qcom,pm8916-gpio"
|
|
- reg: peripheral ID, size of register block
|
|
- gpio-controller
|
|
- gpio-count: number of GPIOs
|
|
- #gpio-cells: 2
|
|
|
|
Optional properties:
|
|
- gpio-bank-name: name of bank (as default "pm8916" is used)
|
|
|
|
Example:
|
|
|
|
pmic_gpios: gpios@c000 {
|
|
compatible = "qcom,pm8916-gpio";
|
|
reg = <0xc000 0x400>;
|
|
gpio-controller;
|
|
gpio-count = <4>;
|
|
#gpio-cells = <2>;
|
|
gpio-bank-name="pmic";
|
|
};
|
|
|
|
|
|
2) Power/Reset key driver
|
|
|
|
Required properties:
|
|
- compatible: "qcom,pm8916-pwrkey"
|
|
- reg: peripheral ID, size of register block
|
|
- gpio-controller
|
|
- #gpio-cells: 2
|
|
|
|
Optional properties:
|
|
- gpio-bank-name: name of bank (as default "pm8916_key" is used)
|
|
|
|
|
|
Example:
|
|
|
|
pmic_pon: pon@800 {
|
|
compatible = "qcom,pm8916-pwrkey";
|
|
reg = <0x800 0x96>;
|
|
#gpio-cells = <2>;
|
|
gpio-controller;
|
|
};
