Actions Semi S700 Pin Controller
|
||||
|
||||
This binding describes the pin controller found in the S700 SoC.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: Should be "actions,s700-pinctrl"
|
||||
- reg: Should contain the register base address and size of
|
||||
the pin controller.
|
||||
- clocks: phandle of the clock feeding the pin controller
|
||||
- gpio-controller: Marks the device node as a GPIO controller.
|
||||
- gpio-ranges: Specifies the mapping between gpio controller and
|
||||
pin-controller pins.
|
||||
- #gpio-cells: Should be two. The first cell is the gpio pin number
|
||||
and the second cell is used for optional parameters.
|
||||
- interrupt-controller: Marks the device node as an interrupt controller.
|
||||
- #interrupt-cells: Specifies the number of cells needed to encode an
|
||||
interrupt. Shall be set to 2. The first cell
|
||||
defines the interrupt number, the second encodes
|
||||
the trigger flags described in
|
||||
bindings/interrupt-controller/interrupts.txt
|
||||
- interrupts: The interrupt outputs from the controller. There is one GPIO
|
||||
interrupt per GPIO bank. The number of interrupts listed depends
|
||||
on the number of GPIO banks on the SoC. The interrupts must be
|
||||
ordered by bank, starting with bank 0.
|
||||
|
||||
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, a group, or a list of pins or groups. This configuration can include the
|
||||
mux function to select on those group(s), and various pin configuration
|
||||
parameters, such as pull-up, drive strength, etc.
|
||||
|
||||
PIN CONFIGURATION NODES:
|
||||
|
||||
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.
|
||||
|
||||
Pinmux functions are available only for the pin groups while pinconf
|
||||
parameters are available for both pin groups and individual pins.
|
||||
|
||||
The following generic properties as defined in pinctrl-bindings.txt are valid
|
||||
to specify in a pin configuration subnode:
|
||||
|
||||
