[PATCH v4 4/4] dt-bindings: pinctrl: qcom,msm8998: convert to dtschema
From: Krzysztof Kozlowski
Date: Mon Oct 17 2022 - 19:47:23 EST
Convert Qualcomm MSM8998 pin controller bindings to DT schema. Keep the
parsing of pin configuration subnodes consistent with other Qualcomm
schemas (children named with '-state' suffix, their children with
'-pins').

Changes since v3:
1. Add Rb tag.
2. Drop entire drive-strength (not needed, brought by common TLMM
schema).
Changes since v2:
1. Drop default:2 for drive strength.
2. Add Rb tag.
Changes since v1:
1. Correct bindings description.

-Qualcomm MSM8998 TLMM block
-
-This binding describes the Top Level Mode Multiplexer block found in the
-MSM8998 platform.
-
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be "qcom,msm8998-pinctrl"
-
-- reg:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: the base address and size of the TLMM register space.
-
-- interrupts:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: should specify the TLMM summary IRQ.
-
-- 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
- Value type: <u32>
- Definition: must be 2. Specifying the pin number and flags, as defined
- in <dt-bindings/gpio/gpio.h>
-

- 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-gpio149
- Supports mux, bias and drive-strength
-
- sdc2_clk, sdc2_cmd, sdc2_data
- Supports bias and drive-strength

- specified pins. Functions are only valid for gpio pins.
