Please break this out into a separate patch that I can take through my
tree.  There is no need for you to bind up changes in multiple
subsystems here.

Ok, I will separate it, thank you.

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.

Patch applied.

However I suggest you use:

unsigned int => u32
unsigned short => u16
unsigned char => u8

These kernel-specific types are more to the point,
you immediately see how many bits they use, so a
patch chaning all of the types to u32/u16/u8 would
be welcome.

This needs to go through the ARM SoC tree, or I need an ACK from
some ARM SoC maintainer if I should take it through the pinctrl
tree.

Since there is a build dependency on the header in pinctrl
ARM SoC would need to pull in some immutable branch
from my tree to take this patch.
