Current EN7581 pinctrl driver supports the following functionalities: - pin multiplexing via chip_scu syscon - pin pull-up, pull-down, open-drain, current strength, {input,output}_enable, output_{low,high} via chip_scu syscon - gpio controller - irq controller --- Changes in v4: - add 'Limitation' description in pwm driver - fix comments in pwm driver - rely on mfd->base __iomem pointer in pwm driver, modify register offsets according to it and get rid of sgpio_cfg, flash_cfg and cycle_cfg pointers - simplify register utility routines in pwm driver - use 'generator' instead of 'waveform' suffix for pwm routines - fix possible overflow calculating duty cycle in pwm driver - do not modify pwm state in free callback in pwm driver - cap the maximum period in pwm driver - do not allow inverse polarity in pwm driver - do not set of_xlate callback in the pwm driver and allow the stack to do it - fix MAINTAINERS file for airoha pinctrl driver - fix undefined reference to __ffsdi2 in pinctrl driver - simplify airoha,en7581-gpio-sysctl.yam binding - Link to v3: https://lore.kernel.org/r/20240831-en7581-pinctrl-v3-0-98eebfb4da66@kernel.org Changes in v3: - introduce airoha-mfd driver - add pwm driver to the same series - model pinctrl and pwm drivers as childs of a parent mfd driver. - access chip-scu memory region in pinctrl driver via syscon - introduce a single airoha,en7581-gpio-sysctl.yaml binding and get rid of dedicated bindings for pinctrl and pwm - add airoha,en7581-chip-scu.yaml binding do the series - Link to v2: https://lore.kernel.org/r/20240822-en7581-pinctrl-v2-0-ba1559173a7f@kernel.org Changes in v2: - Fix compilation errors - Collapse some register mappings for gpio and irq controllers - update dt-bindings according to new register mapping - fix some dt-bindings errors - Link to v1: https://lore.kernel.org/all/cover.1723392444.git.lorenzo@kernel.org/ --- Benjamin Larsson (1): pwm: airoha: Add support for EN7581 SoC Christian Marangi (2): dt-bindings: mfd: Add support for Airoha EN7581 GPIO System Controller mfd: airoha: Add support for Airoha EN7581 MFD Lorenzo Bianconi (2): dt-bindings: arm: airoha: Add the chip-scu node for EN7581 SoC pinctrl: airoha: Add support for EN7581 SoC .../bindings/arm/airoha,en7581-chip-scu.yaml | 42 + .../bindings/mfd/airoha,en7581-gpio-sysctl.yaml | 433 +++ MAINTAINERS | 7 + drivers/mfd/Kconfig | 8 + drivers/mfd/Makefile | 2 + drivers/mfd/airoha-en7581-gpio-mfd.c | 72 + drivers/pinctrl/mediatek/Kconfig | 16 +- drivers/pinctrl/mediatek/Makefile | 1 + drivers/pinctrl/mediatek/pinctrl-airoha.c | 2964 ++++++++++++++++++++ drivers/pwm/Kconfig | 10 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-airoha.c | 414 +++ include/linux/mfd/airoha-en7581-mfd.h | 9 + 13 files changed, 3978 insertions(+), 1 deletion(-) --- base-commit: 264c13114bd71ddfd7b25c7b94f6cda4587eca25 change-id: 20240818-en7581-pinctrl-1bf120154be0 prerequisite-change-id: 20240705-for-6-11-bpf-a349efc08df8:v2 Best regards,
