|
||||
- 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";
|

#address-cells = <1>;

||||

|
