Hi,

There are several patches in this series, and they should go to
different trees. Will it be easier for maintainers if we rearrange
patches in the following order?

  dt-bindings: mediatek: Modify pinctrl bindings for mt6397.
  pinctrl: dt bindings: mt6397: Add pinfunc header file for mt6397.
  pinctrl: mediatek: data struct optimize and remove unused member
  pinctrl: mediatek: add mtk_pctrl_spec_pull_set_samereg common code
  pinctrl: mediatek: add ies/smt control to common code.
  pinctrl: mediatek: add Pinctrl/GPIO driver for mt6397.
  pinctrl: mediatek: add pinctrl/GPIO/EINT driver for mt8127
  mfd: mediatek: add GPIO sub module support into mfd.
  ARM: dts: mt8127: add pinctrl/GPIO/EINT node for mt8127
  arm64: dts: mt8173-evb: add pinctrl/GPIO node for mt6397.
  ARM: dts: mt8135-evbp1: add pinctrl/GPIO node for mt6397.

To avoid build fail, the last 2 should not be merged until the second
one is merged into mainline.
