[PATCH] pinctrl: polarfire: restore GENERIC_PINCONF dependency

[PATCH] pinctrl: polarfire: restore GENERIC_PINCONF dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Changing over to the new CONFIG_GENERIC_PINCTRL dropped the GENERIC_PINCONF
option, causing a build failure:

WARNING: unmet direct dependencies detected for GENERIC_PINCTRL
  Depends on [n]: PINCTRL [=y] && GENERIC_PINCONF [=y] && GENERIC_PINCTRL_GROUPS [=n] && GENERIC_PINMUX_FUNCTIONS [=n]
  Selected by [y]:
  - PINCTRL_POLARFIRE_SOC [=y] && PINCTRL [=y] && (ARCH_MICROCHIP [=y] || COMPILE_TEST [=y]) && OF [=y]
drivers/pinctrl/microchip/pinctrl-mpfs-mssio.c:296:29: error: 'pinctrl_generic_get_group_count' undeclared here (not in a function)

      |                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Select both GENERIC_PINCTRL and GENERIC_PINCONF to address this.

Does this show up with
https://lore.kernel.org/all/20260130-stoop-gleeful-29f2c525bd48@spud/
applied?
I considered what you have here, went with what I linked cos it matches
the other pinctrl core options.

I'm sure that's fine as well.

Same here, I also thought about both options, but picked the other one ;-)

Looking at both again, I agree that your version is better, so
feel free to add

to that one.

I've applied this one now.
