[v1,0/4] pinctrl: mediatek: add driver support driving and resistance property on mt8192

Message

Patch 1 make driver consistent with "drive-strength" properties
  description of  pinctrl-mt8192.yaml

Patch 2 make driver consistent with "mediatek,drive-strength-adv"
  description pinctrl-mt8192.yaml, however, "mediatek,drive-strength-adv"
  description of pinctrl-mt8192.yaml needs to be synchronize a little bit.

Patch 3 Since the bias-pull-{up,down} is generic properties, make
  driver to be used for setting type {PUPD/R1/R0 , PU/PD, PU/PD/RSEL}.

Patch 4 Remove some pins definitions not support PUPD/R1/R0.

Please see the following for detailed  description 

Patch 1 provides generic driving setup, which support 2/4/6/8/10/12/14/16mA
  driving.

Patch 2 provides I2C pins specific driving setup property, can support
  0.125/0.25/0.5/1mA adjustment, and also support driving setup with
  unit microamp.

Patch 3 provides I2C pins pull up/down type which is RSEL. It can support
  RSEL define or si unit value(ohm) to set different resistance

Patch 4 Remove pin definitions that do not support the R0 & R1 pinconfig
  property

Guodong Liu (4):
  pinctrl: add generic driving setup property on mt8192
  pinctrl: add drive for I2C related pins on mt8192
  pinctrl: mediatek: add rsel setting on mt8192
  pinctrl: mediatek: fix the pinconf definition of some GPIO pins
