For stm32h7's new board support , I guess following the stm32f7/stm32f4's style
is a reasonable way to do it, but add a little optimization。
which means :
old structure
stm32h7-pinctrl.dtsi --> stm32h743-pinctrl.dtsi (referenced by
stm32h743i-disco, -eval)
|--> stm32h750-pinctrl.dtsi
(referenced by stm32h750i-art-pi, etc)
add art-pi other board's pin definition in stm32h750-pinctrl.dtsi with
xxx_pins_a, xxx_pins_b
xxx_pins_a used for art-pi, xxx_pins_b used for other boards.
after more boards add in support, there will be more xxx_pin_c, .... defined
as the pin map is according to the hardware schematic diagram io connection.
so, why not move xxx_pin_x to a board specific place. such as
stm32h750i-art-pi.dts
new structure:
1, rename stm32h743-pinctrl.dtsi to stm32h7-pinctrl.dtsi (only
preserve gpioa...k,)
2, move xxx_pins_x from stm32h7-pinctrl.dtsi to
stm32h7xx-disco/eval/art-pi/etc.dts (as they depends on hardware
schematic)
stm32h7-pinctrl.dtsi --> stm32h743i-discon.dts
|--> stm32h743i-eval.dts
|--> stm32h750i-art-pi.dts
|--> stm32h7xxx.dts
would you agree this ?

Oh, i forget to add pin driver under drivers/pinctrl/stm32/
will add it next time.
