Subject: Re: [PATCH v2 1/5] pinctrl: mediatek: add generic driving
setup property on mt8192

Hi Guodong,

please see comments below.

2/4/6/8/10/12/14/16mA driving, original driver just set raw data
setup setting when use drive-strength property.

This commit message is a bit confusing, I suggest using the following
commit
message instead:

The dt-binding expects the drive-strength arguments to be passed in mA,
but the
driver was using callbacks that expect raw values instead. Change the
callbacks
for the ones that operate on mA values, so that the driver is in
accordance to
the dt-binding.

The drive-strength property requiring values in mA is the standard and
other
MediaTek SoCs of the same generation already do the same, so this
change avoids
mt8192 having a non-standard property.

There are no current upstream users of this driver, so this change
doesn't cause
any regression.

Fixed in next patch, thanks!
