Subject: [PATCH v2 1/3] dt-bindings: pinctrl: qcom,msm8960: convert to dtschema

Convert Qualcomm MSM8960 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').

Signed-off-by: Krzysztof Kozlowski <[email protected]>

Changes since v1:
1. Correct gpio pattern.

-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-gpio151,
- sdc1_clk,
- sdc1_cmd,

I'm changing this to "gsbi1" while applying this patch.
