[PATCH v5 0/2] pinctrl: nuvoton: add driver for NPCM7xx

From: Tomer Maimon
Date: Mon Aug 06 2018 - 11:24:44 EST


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.
