This series implements a set of drivers allowing to support the Maxim Integrated MAX7360 device. The MAX7360 is an I2C key-switch and led controller, with following functionalities: - Keypad controller for a key matrix of up to 8 rows and 8 columns. - Rotary encoder support, for a single rotary encoder. - Up to 8 PWM outputs. - Up to 8 GPIOs with support for interrupts and 6 GPOs. Chipset pins are shared between all functionalities, so all cannot be used at the same time. Signed-off-by: Mathieu Dubois-Briand <mathieu.dubois-briand@xxxxxxxxxxx> --- Changes in v5: - Add pinctrl driver to replace the previous use of request()/free() callbacks for PORT pins. - Remove ngpios property from GPIO device tree bindings. - Use GPIO valid_mask to mark unusable keypad columns GPOs, instead of changing ngpios. - Drop patches adding support for request()/free() callbacks in GPIO regmap and gpio_regmap_get_ngpio(). - Allow gpio_regmap_register() to create the associated regmap IRQ. - Various fixes in MFD, PWM, GPIO and KEYPAD drivers. - Link to v4: https://lore.kernel.org/r/20250214-mdb-max7360-support-v4-0-8a35c6dbb966@xxxxxxxxxxx Changes in v4: - Modified the GPIO driver to use gpio-regmap and regmap-irq. - Add support for request()/free() callbacks in gpio-regmap. - Add support for status_is_level in regmap-irq. - Switched the PWM driver to waveform callbacks. - Various small fixes in MFD, PWM, GPIO drivers and dt bindings. - Rebased on v6.14-rc2. - Link to v3: https://lore.kernel.org/r/20250113-mdb-max7360-support-v3-0-9519b4acb0b1@xxxxxxxxxxx Changes in v3: - Fix MFD device tree binding to add gpio child nodes. - Fix various small issues in device tree bindings. - Add missing line returns in error messages. - Use dev_err_probe() when possible. - Link to v2: https://lore.kernel.org/r/20241223-mdb-max7360-support-v2-0-37a8d22c36ed@xxxxxxxxxxx Changes in v2: - Removing device tree subnodes for keypad, rotary encoder and pwm functionalities. - Fixed dt-bindings syntax and naming. - Fixed missing handling of requested period in PWM driver. - Cleanup of the code - Link to v1: https://lore.kernel.org/r/20241219-mdb-max7360-support-v1-0-8e8317584121@xxxxxxxxxxx --- Kamel Bouhara (2): mfd: Add max7360 support pwm: max7360: Add MAX7360 PWM support Mathieu Dubois-Briand (9): dt-bindings: mfd: gpio: Add MAX7360 pinctrl: Add MAX7360 pinctrl driver regmap: irq: Add support for chips without separate IRQ status gpio: regmap: Allow to allocate regmap-irq device gpio: regmap: Allow to provide init_valid_mask callback gpio: max7360: Add MAX7360 gpio support input: keyboard: Add support for MAX7360 keypad input: misc: Add support for MAX7360 rotary MAINTAINERS: Add entry on MAX7360 driver .../bindings/gpio/maxim,max7360-gpio.yaml | 83 +++++++ .../devicetree/bindings/mfd/maxim,max7360.yaml | 170 +++++++++++++ MAINTAINERS | 13 + drivers/base/regmap/regmap-irq.c | 97 +++++--- drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-max7360.c | 246 +++++++++++++++++++ drivers/gpio/gpio-regmap.c | 26 +- drivers/input/keyboard/Kconfig | 12 + drivers/input/keyboard/Makefile | 1 + drivers/input/keyboard/max7360-keypad.c | 264 +++++++++++++++++++++ drivers/input/misc/Kconfig | 11 + drivers/input/misc/Makefile | 1 + drivers/input/misc/max7360-rotary.c | 161 +++++++++++++ drivers/mfd/Kconfig | 14 ++ drivers/mfd/Makefile | 1 + drivers/mfd/max7360.c | 185 +++++++++++++++ drivers/pinctrl/Kconfig | 11 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-max7360.c | 195 +++++++++++++++ drivers/pwm/Kconfig | 11 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-max7360.c | 194 +++++++++++++++ include/linux/gpio/regmap.h | 22 ++ include/linux/mfd/max7360.h | 112 +++++++++ include/linux/regmap.h | 3 + 26 files changed, 1813 insertions(+), 35 deletions(-) --- base-commit: a64dcfb451e254085a7daee5fe51bf22959d52d3 change-id: 20241219-mdb-max7360-support-223a8ce45ba3 Best regards, -- Mathieu Dubois-Briand <mathieu.dubois-briand@xxxxxxxxxxx>
