- "amlogic,meson-a1-periphs-pinctrl"
- "amlogic,meson-s4-periphs-pinctrl"
- - reg: address and size of registers controlling irq functionality
-
-=== GPIO sub-nodes ===
-
-The GPIO bank for the controller is represented as a sub-node and it acts as a
-GPIO controller.
-
-Required properties for sub-nodes are:
- - reg: should contain a list of address and size, one tuple for each entry
- in reg-names.
- - reg-names: an array of strings describing the "reg" entries.
- Must contain "mux" and "gpio".
- May contain "pull", "pull-enable" and "ds" when appropriate.
- - gpio-controller: identifies the node as a gpio controller
- - #gpio-cells: must be 2
-
-=== Other sub-nodes ===
-
-Child nodes without the "gpio-controller" represent some desired
-configuration for a pin or a group. Those nodes can be pinmux nodes or
-configuration nodes.
-
-Required properties for pinmux nodes are:
- - groups: a list of pinmux groups. The list of all available groups
- depends on the SoC and can be found in driver sources.
- - function: the name of a function to activate for the specified set
- of groups. The list of all available functions depends on the SoC
- and can be found in driver sources.
-
-Required properties for configuration nodes:
- - pins: a list of pin names
-
-Configuration nodes support the following generic properties, as
-described in file pinctrl-bindings.txt:
- - "bias-disable"
- - "bias-pull-up"
- - "bias-pull-down"
- - "output-enable"
- - "output-disable"
- - "output-low"
- - "output-high"
-
-Optional properties :
- - drive-strength-microamp: Drive strength for the specified pins in uA.
- This property is only valid for G12A and newer.
-
-=== Example ===
-
- pinctrl: pinctrl@c1109880 {
- compatible = "amlogic,meson8-cbus-pinctrl";
- reg = <0xc1109880 0x10>;
- #address-cells = <1>;

- <0xc1108120 0x18>,
- <0xc1108030 0x30>;
