Subject: [PATCH v4 00/13] MediaTek pinctrl DT binding cleanup and MT6735 pinctrl support

From: Yassine Oudjana <y.oudjana@...tonmail.com>

This series adds a driver for the pin controller found on the MediaTek MT6735
and MT6735M SoCs. The two differ in the last 6 physical pins, which are used
for MSDC2 on MT6735 but don't exist on MT6735M (since MSDC2 doesn't exist on it
to begin with). In preparation to document DT bindings for this pin controller,
the existing documents for MT67xx SoCs are combined into one in order to
eliminate duplicate property definitions and standardize pin configuration node
names. Necessary cleanup is done along the way.

Changes since v3:
 - Improve interrupts description to make clear what sysirq means.
 - Set drive-strength constraints per variant.
 - Set maxItems for reg in MT6795.
 - Add blank lines between conditionals.
 - Add ref for both pinmux-node.yaml and pincfg-node.yaml.
 - Make pinctrl subnode-related changes in separate patch.
 - Fix up some pinctrl subnode property descriptions.
 - Add interrupts items descriptions to MT6765 and MT6735.
 
Changes since v2:
 - Add interrupt descriptions.
 - Change interrupts property item limits.
 - Move pinmux examples from node description to example dts.
 - Properly add myself as maintainer for MT6735 pinctrl driver and DT bindings
   document.
 - Remove tabs from a few defines in pinctrl-mt6735.c.

Changes since v1:
 - Combine other documents into existing mediatek,mt6779-pinctrl.yaml
   instead of creating a new document with wild card in its name.
 - Split first patch into smaller patches focused on specific changes.
 - Remove syscon compatible from MT6779 DT to avoid a check error.
 - Fix interrupt count for MT6795.
