These patches are part of a larger effort to support the MT6735 SoC family in mainline Linux. More patches (unsent or sent and pending review or revision) can be found here[1]. 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. [1] https://gitlab.com/mt6735-mainline/linux/-/commits/mt6735-staging Changes since v6: - Mention changing MT6797 DT in 1st patch commit message. - Squash MT6735 DT binding patches. - Add debounce time to eint_hw struct. MT6735 supports the same debounce times as MT6765 so reuse debounce_time_mt6765. Changes since v5: - Revise and fix all register bits for all group register types (IES, SMT, RDSEL, TDSEL, PUPD_R0_R1, PULLEN and PULLSEL). - Add pull_type array. - Use proper getters/setters for bias and drive. - Add minItems for MT6795 interrupts. Changes since v4: - Remove patches that were applied previously. - Define interrupts items for each variant (bringing back maxItems: 1 to the top level definition then adding maxItems: 2 under the MT6795 condition causes a dt_binding_check error for some reason) - Move example changes to the patch they belong to - Don't unnecessarily move the allOf block. 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 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.
