* Allwinner A1X Pin Controller
The pins controlled by sunXi pin controller are organized in banks,
each bank has 32 pins. Each pin has 7 multiplexing functions, with
the first two functions being GPIO in and out. The configuration on
the pins includes drive strength and pull-up.
Required properties:
- compatible: "allwinner,<soc>-pinctrl". Supported SoCs for now are:
sun5i-a13.
- reg: Should contain the register physical address and length for the
pin controller.
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices.
A pinctrl node should contain at least one subnodes representing the
pinctrl groups available on the machine. Each subnode will list the
pins it needs, and how they should be configured, with regard to muxer
configuration, drive strength and pullups. If one of these options is
not set, its actual value will be unspecified.
Required subnode-properties:
- allwinner,pins: List of strings containing the pin name.
- allwinner,function: Function to mux the pins listed above to.
Optional subnode-properties:
- allwinner,drive: Integer. Represents the current sent to the pin
0: 10 mA
1: 20 mA
2: 30 mA
3: 40 mA
- allwinner,pull: Integer.
0: No resistor
1: Pull-up resistor
2: Pull-down resistor
Examples:
pinctrl@01c20800 {
compatible = "allwinner,sun5i-a13-pinctrl";
reg = <0x01c20800 0x400>;
