[PATCH v4 0/2] pinctrl: nuvoton: add driver for NPCM7xx

[Tomer Maimon]

This patch set adds pinmux and GPIO controller for the Nuvoton
NPCM750/730/715/705 Baseboard Management Controller (BMC).

The Nuvoton BMC NPCM750/730/715/705 Pinmux functions accessible
only for pin groups and pinconf parameters available only for 
individual pins.

The Nuvoton BMC NPCM750/730/715/705 has eight identical GPIO 
modules, each module has 32 GPIO ports.

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

The NPCM7xx pinctrl and GPIO driver tested on NPCM750 evaluation board.

this patch set depend on 
gpio: mmio: add inverted direction get_set io support approval.

without adding BGPIOF_INVERTED_REG_DIR to include/linux/gpio/driver.h
the build will failed.
