== Amlogic Meson pinmux controller ==
Required properties for the root node:
- compatible: "amlogic,meson8-pinctrl"
- reg: address and size of registers controlling irq functionality
=== GPIO sub-nodes ===
The 2 power domains of the controller (regular and always-on) are
represented as sub-nodes and each of them acts as a GPIO controller.
Required properties for sub-nodes are:
- reg: should contain address and size for mux, pull-enable, pull and
gpio register sets
- reg-names: an array of strings describing the "reg" entries. Must
contain "mux", "pull" and "gpio". "pull-enable" is optional and
when it is missing the "pull" registers are used instead
- gpio-controller: identifies the node as a gpio controller
- #gpio-cells: must be 2
Valid sub-node names are:
- "banks" for the regular domain
- "ao-bank" for the always-on domain
=== 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 generic properties "bias-disable",
"bias-pull-up" and "bias-pull-down", described in file

Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
a general description of GPIO and interrupt bindings.
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices, including the meaning of the
phrase "pin configuration node".
The pin configuration nodes act as a container for an arbitrary number of
subnodes. Each of these subnodes represents some desired configuration for a
pin or a list of pins. This configuration can include the
mux function to select on those pin(s), and various pin configuration
parameters, as listed below.
SUBNODES:
The name of each subnode is not important; all subnodes should be enumerated
and processed purely based on their content.
Each subnode only affects those parameters that are explicitly listed. In
other words, a subnode that lists a mux function but no pin configuration
parameters implies no information about any pin configuration parameters.
Similarly, a pin subnode that describes a pullup parameter implies no
information about e.g. the mux function.
The following generic properties as defined in pinctrl-bindings.txt are valid
to specify in a pin configuration subnode:
