The mt8186 contains 8 GPIO physical address bases that correspond to
the 'reg-names' of the pinctrl driver. The 'reg-names' entries in
bindings are ordered incorrectly, though. The system crashes due of an
erroneous address when the regulator initializes.

We fix the 'reg-names' for the pinctrl nodes and the pinctrl-mt8186
example in bindings.

The sender's (your) signed-off-by should come last [1]. Also, what is the
participation of Guodong in this patch? If Guodong helped in writing the patch
there should also be a Co-developed-by tag for Guodong, as shown in [1].

Also, you should avoid making changes that don't have to do with the patch
itself. This patch is about fixing the reg names, so no need to touch the
formatting of addresses. It just adds noise.

Other than that,

Guodong and I consult on this patch. I will add a Co-developed-by tag
for Guodong.

Ok, no problem. I will remove unrelated part.
