[PATCH linux dev-5.15 v1 0/2] pinctrl: nuvoton: add pinmux and GPIO driver for NPCM8XX

[Tomer Maimon]

This patch set adds pinmux and GPIO controller for the Arbel NPCM8XX 
Baseboard Management Controller (BMC).

Arbel BMC NPCM8XX pinctrl driver based on Poleg NPCM7XX, except the
pin mux mapping difference the NPCM8XX GPIO supports adjust debounce
period time.

Arbel BMC NPCM8XX Pinmux functions accessible only for pin groups 
and pin configuration parameters available only for individual pins.

Arbel BMC NPCM8XX has eight identical GPIO modules,
each module has 32 GPIO ports.

Most of the GPIO ports are multiplexed with other system functions.

The NPCM8XX pinctrl and GPIO driver was tested on the Arbel NPCM8XX evaluation 
board that running Arbel OpenBMC.

This patchset is based on the Arbel NPCM8XX pinctrl and GPIO 5.19 kernel patchset.
