You do not "just" rename but you keel also the old version. I don't
agree with this approach. You have first to rename
stm32h743-pinctrl.dtsi to stm32h7-pinctrl.dtsi (keeping copyright as
they are please) and modify existing H7 boards which currently use
stm32h743-pinctrl.dtsi.
Then you create a second patch adding your pingroups.
Now regarding "st,stm32h750-pinctrl", I see a patch dealing with this
new binding but no update on driver side. Do I miss something ? what are
differences between h743 and h750 regarding pinctrl ?
Regards
Alex
