This patch adds basic SoC support for Mediatek's new 4-core SoC,
MT7986, which is mainly for wifi-router application.

---
v3: updated mt7986 pinctrl releated dt-bindig,
    updated mt7986 pinctrl driver according to reviewers's suggestion
    fixed wrong clock ID in mt7986-clock-IDs
    added Acked-by tag in some patches
v2: updated mt7986 clock releated IDs, dt-binding, and driver
    updated mt7986 clock releated dt-binding and driver
    updated device tree of mt7986a and mt7986b

Sam Shih (9):
  dt-bindings: clock: mediatek: document clk bindings for mediatek
    mt7986 SoC
  clk: mediatek: add mt7986 clock IDs
  clk: mediatek: add mt7986 clock support
  pinctrl: mediatek: moore: check if pin_desc is valid before use
  dt-bindings: pinctrl: update bindings for MT7986 SoC
  pinctrl: mediatek: add support for MT7986 SoC
  dt-bindings: arm64: dts: mediatek: Add mt7986 series
  arm64: dts: mediatek: add mt7986a support
  arm64: dts: mediatek: add mt7986b support
