Lantiq XWAY pinmux controller

|
Required properties:
|
|
- compatible: "lantiq,pinctrl-xway", (DEPRECATED: Use "lantiq,pinctrl-danube")
|
|
"lantiq,pinctrl-xr9", (DEPRECATED: Use "lantiq,xrx100-pinctrl" or
|
|
"lantiq,xrx200-pinctrl")
|
|
"lantiq,pinctrl-ase", (DEPRECATED: Use "lantiq,ase-pinctrl")
|
|
"lantiq,<chip>-pinctrl", where <chip> is:
|
|
"ase" (XWAY AMAZON Family)
|
|
"danube" (XWAY DANUBE Family)
|
|
"xrx100" (XWAY xRX100 Family)
|
|

|
|
"xrx300" (XWAY xRX300 Family)
|
|
- reg: Should contain the physical address and length of the gpio/pinmux
|
|
register range
|
|
|
|
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".
|
|
|
|
Lantiq's pin configuration nodes act as a container for an arbitrary number of
|
|
subnodes. Each of these subnodes represents some desired configuration for a
|
|
pin, a group, or a list of pins or groups. This configuration can include the
|
|
mux function to select on those group(s), and two pin configuration parameters:
|
|
pull-up and open-drain
|
|
|
|
The name of each subnode is not important as long as it is unique; 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.
|
|
|
|
We support 2 types of nodes.

|

Definition of mux function groups:

|
Required subnode-properties:
|
|
- lantiq,groups : An array of strings. Each string contains the name of a group.

|
|
group. Valid values for function names are listed below.
