changes since v2:

- Patch 1 Optimize commit message description.

- Patch 3 Fix careless character missing the closing '/'.

- Patch 4 Optimize commit message description.

changes since v1:

- Patch 1 Add commit only, add "mediatek:" on the commit title for this
patch, describe the patch modification in detail.

- Patch 2  Add commit only, add "mediatek:" on the commit title for this
patch, use space instead of tab before the =, Dropping E1, E0, and EN
arrays in this patch, which were used by the original advanced
drive configuration.

- Patch 3 Add commit describe the patch modification in detail,
add the missing pull type array for mt8192 to document the pull type of
each pin and prevent invalid pull type settings. use space instead of
tab after the ,.

- Patch 4 Remove the original advanced drive configuration.

- Patch 5 Remove pin definitions that do not support the R0 & R1
pinconfig property.

v1:

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
