Add Nuvoton BMC NPCM845 Pinmux and Pinconf support.
Signed-off-by: Stanley Chu yschu@nuvoton.com --- v5: - lower-case hex consistently - use uint type for pin list in the group_config struct v4: - correct the pin flags, add slew rate control suuport for rgmii pins v3: - separate group names and function names in different tables to allow for adding additional functions v2: - drop the WDnRCRB/CORSTCB register access, it is not for GPIO modules reset control --- drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/nuvoton/Kconfig | 12 + drivers/pinctrl/nuvoton/Makefile | 1 + drivers/pinctrl/nuvoton/pinctrl-npcm8xx.c | 1185 +++++++++++++++++++++ 5 files changed, 1200 insertions(+) create mode 100644 drivers/pinctrl/nuvoton/Kconfig create mode 100644 drivers/pinctrl/nuvoton/Makefile create mode 100644 drivers/pinctrl/nuvoton/pinctrl-npcm8xx.c
