    Subject[PATCH v5 6/7] dt-bindings: pinctrl: mediatek,mt6779-pinctrl: Document MT6735 pin controller
    Date
    From: Yassine Oudjana <y.oudjana@protonmail.com>

    Add bindings for the pin controller found on MediaTek MT6735 and
    MT6735M SoCs, including describing a method to manually specify
    a pin and function in the pinmux property making defining bindings
    for each pin/function combination unnecessary. The pin controllers
    on those SoCs are generally identical, with the only difference
    being the lack of MSDC2 pins (198-203) on MT6735M.
