There are some notable differences, however: - The addresses of GPIO banks are not physical addresses but simple indices (0 to 7), because the GPIO registers are not laid out in convenient blocks. - Pinmux settings can explicitly specify that the GPIO mode is used. Certain pins support blink patterns in hardware. This is currently not modelled in the DT binding.

Notable differences: - WPCM450, the GPIO registers are not organized in multiple banks, but rather placed continually into the same register block. This affects how register offsets are computed. - Pinmux nodes can explicitly select GPIO mode, whereas, in the npcm7xx driver, this happens automatically when a GPIO is requested. Some functionality implemented in the hardware was (for now) left unused in the driver, specifically blinking and pull-up/down. Signed-off-by: Jonathan Neuschäfer --- This patch now depends on gpio/for-next, specifically these patches: - gpiolib: improve coding style for local variables - gpiolib: allow to specify the firmware node in struct gpio_chip - gpiolib: of: make fwnode take precedence in struct gpio_chip This patch has a few checkpatch warnings, which are inherited from the pinctrl-npcm7xx driver. I decided to ignore those. Specifically: (1) WPCM450_GRPS is an unwrapped list; (2) use of -ENOTSUPP is discouraged. v3: - make gc the first member of struct wpcm450_gpio, to simplify pointer arithmetic - Add empty line between includes and includes - Add a comment explaining wpcm450_gpio_fix_evpol - Use generic_handle_domain_irq - Rename struct fwnode_handle *np to child - Convert instances of dev_err() to dev_err_probe() and simplify return - Use device_for_each_child_node loop - Remove gpio->gc.parent assignment (already done in bgpio_init) - Move gpiochip_add_pin_range() to .add_pin_ranges callback - Use GENMASK in calculation of IRQ bitmask - I decided to keep using __assign_bit throughout the driver, because it keeps the code short - Remove nuvoton,interrupt-map again, to simplify the binding - Use gpio_chip->fwnode - I decided against using the bitmap_* API in(place of) wpcm450_gpio_irq_bitnum, etc., because I find the current solution clear enough, even though the mapping functions are somewhat verbose. v2: - https://lore.kernel.org/lkml/20211207210823.1975632-6-j.neuschaefer@gmx.net/ - Adjust to binding change which put each GPIO bank into its own node - Use generic GPIO support - Make it possible to set pinmux to GPIO explicitly - Allow building the driver as a module - Fix spelling of "spin lock" in text - Include - Move linux/pinctrl/* headers to the end of the #include block - Remove/rework comments and printk messages - Switch to fwnode API - Remove comma after sentinel {} - Use dev_err_probe - Improve Kconfig help message - Declare for_each_set_bit iterator as unsigned int - Use __assign_bit - Set parent irq handler in set_irq_type callback - Use struct group_desc - Don't hide sysfs bind attributes - Remove unnecessary check for gpio-controller property - Use module_platform_driver() v1: - https://lore.kernel.org/lkml/20210602120329.2444672-6-j.neuschaefer@gmx.net/ --- MAINTAINERS | 1 + drivers/pinctrl/Makefile | 2 +- drivers/pinctrl/nuvoton/Kconfig | 18 + drivers/pinctrl/nuvoton/Makefile | 1 + drivers/pinctrl/nuvoton/pinctrl-wpcm450.c | 1132 +++++++++++++++++++++ 5 files changed, 1153 insertions(+), 1 deletion(-) create mode 100644 drivers/pinctrl/nuvoton/pinctrl-wpcm450.c -- 2.30.2 diff --git a/MAINTAINERS b/MAINTAINERS index 123c967936785..cd66185163da5 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -2352,6 +2352,7 @@ S: Maintained F: Documentation/devicetree/bindings/*/*wpcm* F: arch/arm/boot/dts/nuvoton-wpcm450* F: arch/arm/mach-npcm/wpcm450.c +F: drivers/*/*/*wpcm* F: drivers/*/*wpcm* ARM/NXP S32G ARCHITECTURE diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile index 5e63de2ffcf41..823ff12847ed3 100644 --- a/drivers/pinctrl/Makefile +++ b/drivers/pinctrl/Makefile @@ -58,7 +58,7 @@ obj-y += freescale/ obj-$(CONFIG_X86) += intel/ obj-y += mvebu/ obj-y += nomadik/ -obj-$(CONFIG_ARCH_NPCM7XX) += nuvoton/ +obj-y += nuvoton/ obj-$(CONFIG_PINCTRL_PXA) += pxa/ obj-$(CONFIG_ARCH_QCOM) += qcom/ obj-$(CONFIG_PINCTRL_RALINK) += ralink/ diff --git a/drivers/pinctrl/nuvoton/Kconfig b/drivers/pinctrl/nuvoton/Kconfig index 48ba0469edda6..6a3c6f2a73f2d 100644 --- a/drivers/pinctrl/nuvoton/Kconfig +++ b/drivers/pinctrl/nuvoton/Kconfig @@ -1,4 +1,22 @@ # SPDX-License-Identifier: GPL-2.0-only + +config PINCTRL_WPCM450 + tristate "Pinctrl and GPIO driver for Nuvoton WPCM450" + depends on ARCH_WPCM450 || COMPILE_TEST + select PINMUX + select PINCONF + select GENERIC_PINCONF + select GPIOLIB + select GPIO_GENERIC + select GPIOLIB_IRQCHIP + help + Say Y or M here to enable pin controller and GPIO support for + the Nuvoton WPCM450 SoC.
