[PATCH] dt-bindings: pinctrl: qcom,msm8976: convert to dtschema

[PATCH] dt-bindings: pinctrl: qcom,msm8976: convert to dtschema

[Krzysztof Kozlowski]

Convert Qualcomm MSM8976 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 during conversion: update the list of non-mux pins (like sdc1)
to match Linux driver.

-
-Please refer to pinctrl-bindings.txt in this directory for details of the

-
-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.

As usual with these Qcom bindings I simply expect to get it in
a big pull request from you later on :)

I thought I read earlier that the description shouldn't describe the DT
format: should this be `state` instead of `subnode` (same in the
description above)?

Shouldn't this be alphabetical (disregarding `#`), where cells <
controller? (same for interrupt-controller below)

I retract my review on this patch, see below.

Missing a comma between 'qdsd_data3' and 'sdc1_clk', making the bindings
checker treat this as a single string 'qdsd_data3 sdc1_clk'.
