Qualcomm QCS404 TLMM block
This binding describes the Top Level Mode Multiplexer block found in the
QCS404 platform.

Usage: required
Value type: <string>
Definition: must be "qcom,qcs404-pinctrl"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: the base address and size of the north, south and east TLMM
tiles.

Defintiion: names for the cells of reg, must contain "north", "south"
and "east".

- interrupt-controller:
Usage: required
Value type: <none>
Definition: identifies this node as an interrupt controller
- #interrupt-cells:
Usage: required
Value type: <u32>
Definition: must be 2. Specifying the pin number and flags, as defined
in <dt-bindings/interrupt-controller/irq.h>
- gpio-controller:
Usage: required
Value type: <none>
Definition: identifies this node as a gpio controller
- #gpio-cells:
Usage: required

Definition: must be 2. Specifying the pin number and flags, as defined
in <dt-bindings/gpio/gpio.h>
- gpio-ranges:
Usage: required
Definition: see ../gpio/gpio.txt
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, a group, or a list of pins or groups. This configuration can include the
mux function to select on those pin(s)/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.
The following generic properties as defined in pinctrl-bindings.txt are valid
to specify in a pin configuration subnode:
- pins:
Usage: required
Value type: <string-array>
Definition: List of gpio pins affected by the properties specified in
this subnode.
Valid pins are:
gpio0-gpio119
Supports mux, bias and drive-strength
sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd,
sdc2_data
Supports bias and drive-strength
ufs_reset
Supports bias and drive-strength
- function:
Usage: required
Value type: <string>
Definition: Specify the alternative function to be configured for the
specified pins. Functions are only valid for gpio pins.
