=============================
Aspeed AST2400 Pin Controller
=============================
Required properties for the AST2400:
- compatible : Should be one of the following:
"aspeed,ast2400-pinctrl"
"aspeed,g4-pinctrl"
The pin controller node should be the child of a syscon node with the required
property:
- compatible : Should be one of the following:
"aspeed,ast2400-scu", "syscon", "simple-mfd"
"aspeed,g4-scu", "syscon", "simple-mfd"
Refer to the the bindings described in
Documentation/devicetree/bindings/mfd/syscon.txt
Subnode Format
==============
The required properties of pinmux child nodes are:
- function: the mux function to select
- groups : the list of groups to select with this function
Required properties of pinconf child nodes are:
- groups: A list of groups to select (either this or "pins" must be
specified)
- pins : A list of ball names as strings, eg "D14" (either this or "groups"
must be specified)
Optional properties of pinconf child nodes are:
- bias-disable : disable any pin bias
- bias-pull-down: pull down the pin
- drive-strength: sink or source at most X mA
Definitions are as specified in
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt, with any
further limitations as described above.
For pinmux, each mux function has only one associated pin group. Each group is
named by its function. The following values for the function and groups
properties are supported:
ACPI ADC0 ADC1 ADC10 ADC11 ADC12 ADC13 ADC14 ADC15 ADC2 ADC3 ADC4 ADC5 ADC6
ADC7 ADC8 ADC9 BMCINT DDCCLK DDCDAT EXTRST FLACK FLBUSY FLWP GPID GPID0 GPID2
