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 were tested on NPCM845 evaluation board. Addressed comments from: - Andy Shevchenko: https://lkml.org/lkml/2022/7/14/1218 - Rob Herring: https://lkml.org/lkml/2022/7/18/1165 - Krzysztof Kozlowski: https://lkml.org/lkml/2022/9/19/68 https://lkml.org/lkml/2022/7/14/757 Changes since version 2: - Pin controller driver         - Modify kernel configuration.         - Adding and removing include files.         - Using the same register format size.         - Reducing lines by command combination.         - Remove unnecessary parentheses use.         - Use GENMASK and BIT macros.         - Using traditional patterns.  - Pin controller dt-binding         - Modify GPIO description.         - pintcrtl node name, Sorry, I know we have a long discussion about it.         Still, I think the best header pinctrl node name is pinctrl@f0800000.         because the pin mux is handled through the GCR. BTW, same pinctrl header name is used in the NPCM7XX pinctrl version. https://elixir.bootlin.com/linux/v6.0-rc6/source/arch/arm/boot/dts/nuvoton-common-npcm7xx.dtsi#L560 Changes since version 1: - Pin controller driver - Remove unnecessary debug prints and comments. - Use fwnode functions. - Remove Redundant 'else'. - Use switch case instead of else if. - Use GENMASK and BIT macros. - Use dev_err_probe in probe error. - Use callback GPIO range. - Add GCR phandle property. - Parameter order in reversed xmas - Pin controller dt-binding - Modify name from pin to mux. - Add phandle property.
