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. Addressed comments from:. - Linus Walleij: https://www.spinics.net/lists/devicetree/msg243012.html conversion about it with Linus Walleij: - https://www.spinics.net/lists/devicetree/msg241973.html Changes since version 4: - Use direct access read and write functions. - Modify the probe GPIO and pinctrl order. - Remove unsupported BGPIOF_INVERTED_REG_DIR flag. - dt-binding documentation haven't changed. Changes since version 3: - Remove Kconfig MFD_SYSCON dependency. - Add BGPIOF_INVERTED_REG_DIR flag. - dt-binding documentation haven't changed. Changes since version 2: - Using GPIO_GENERIC (mmio). - Add Kconfig MFD_SYSCON dependency. - Remove unnecessary code from the direction output function. - dt-binding documentation haven't changed. Changes since version 1: - Remove Kconfig MFD_SYSCON dependency. - Modify setfunc function. - Modify dt-binding documentation according Rob comments.
