Subject: [PATCH v2 0/4] Add support for mt6878 pinctrl

Hi all,

This patchset adds support for the pin controller found in the MediaTek
MT6878 SoC. This SoC has 9 pinctrl groups, and 4 EINT controller
instances.

This SoC also uses the new "eh" bit for controlling i2c driving, support
for which is also added here.

Changes in V2:
- (Krzysztof) Move over the pinfunc macro header to dts directory
- (Angelo) Drop useless eh bit commit
- (Angelo) Fix s-o-b on debounce times
- (Angelo) Massively simplify pinctrl driver, use PIN_FIELD macro,
  change eh to drv_adv

Kind regards,
Igor
