Aspeed AST2500 Pin Controller
|
|
||||||
=============================
|
|
||||||
|
|
||||||
Required properties for g5:
|
|
||||||
- compatible : Should be one of the following:
|
|
||||||
"aspeed,ast2500-pinctrl"
|
|
||||||
"aspeed,g5-pinctrl"
|
|
||||||
|
|
||||||
- aspeed,external-nodes: A cell of phandles to external controller nodes:
|
|
||||||
0: compatible with "aspeed,ast2500-gfx", "syscon"
|
|
||||||
1: compatible with "aspeed,ast2500-lhc", "syscon"
|
|
||||||
|
|
||||||
The pin controller node should be the child of a syscon node with the required
|
|
||||||
property:
|
|
||||||
|
|
||||||
- compatible : Should be one of the following:
|
|
||||||
"aspeed,ast2500-scu", "syscon", "simple-mfd"
|
|
||||||
"aspeed,g5-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:
|
