-* Allwinner P2WI (Push/Pull 2 Wire Interface) controller
-
-Required properties :
-
- - reg : Offset and length of the register set for the device.
- - compatible : Should one of the following:
- - "allwinner,sun6i-a31-p2wi"
- - interrupts : The interrupt line connected to the P2WI peripheral.
- - clocks : The gate clk connected to the P2WI peripheral.
- - resets : The reset line connected to the P2WI peripheral.
-
-Optional properties :
-
- - clock-frequency : Desired P2WI bus clock frequency in Hz. If not set the
-default frequency is 100kHz
-
-A P2WI may contain one child node encoding a P2WI slave device.
-
-Slave device properties:
- Required properties:
- - reg : the I2C slave address used during the initialization
- process to switch from I2C to P2WI mode
-
-Example:
-
- p2wi@1f03400 {
- compatible = "allwinner,sun6i-a31-p2wi";
- reg = <0x01f03400 0x400>;
- interrupts = <0 39 4>;
- clocks = <&apb0_gates 3>;
- clock-frequency = <6000000>;
- resets = <&apb0_rst 3>;
-
- axp221: pmic@68 {
- compatible = "x-powers,axp221";
- reg = <0x68>;
-
- /* ... */
- };
- };
