Subject: Re: [PATCH 1/2] pinctrl: mediatek: add pinctrl support for MT7629 SoC
Hi, Ryder
The driver follows the new core and looks really clean to me. The only
thing should be pointed out here, that is, should we add new groups
and functions for these wifi used pins?

if "wf0_5g" and "wf0_2g" are groups dedicated for wifi, creating a new
group and function "wifi" would make sense and be more intuitive.

it looks like these pins are used to coexist with an external
bluetooth device or other radio.

"ext" doesn't clearly mean a function. it should be worth a name
allowing us to understand easily these pin groups belong to what
funciton.
