It includes updates to the mmio gpio driver, the addition of device tree bindings, the HDP driver, and updates to the device tree files for STM32MP13, STM32MP15, and STM32MP25 SoCs. The series also updates the MAINTAINERS file to include myself as the maintainer for the STM32 HDP driver and adds the necessary pinmux configurations for HDP pins on STM32MP157C-DK2 as example. Signed-off-by: Clément Le Goffic --- Changes in v4: - 's/Add/add/g' in MAINTAINERS commit message. - Fix the (wrong) status update for the thermal node in stm32mp131.dtsi file. - Do not enable HDP by default during compile testing. - Change the bindings file name: 's/st,stm32-pinctrl-hdp.yaml/st,stm32-hdp.yaml/g' - Add Krzysztof Kozlowski's 'Reviewd-by' trailer on bindings. - Link to v3: https://lore.kernel.org/r/20250523-hdp-upstream-v3-0-bd6ca199466a@foss.st.com Changes in v3: - Use `bgpio_init()` function: - Add add patch to create the `BGPIOF_NO_INPUT` flag needed for the `bgpio_setup_direction()` used in `bgpio_init()` - Remove `stm32_hdp_gpio_get` and `stm32_hdp_gpio_set` - Use `static` pm ops - Update bindings: - add pattern instruction for pin values - remove function's maxItems to use `function: true` - fix the compatible in the exemples - Link to v2: https://lore.kernel.org/r/20250520-hdp-upstream-v2-0-53f6b8b5ffc8@foss.st.com Changes in v2: - Remove bindings header files with function name as #define - Add match_data with function name for three compatible: "st,stm32mp131-hdp", "st,stm32mp151-hdp" and "st,stm32mp251-hdp". - Rework a bit the driver to use match_data. - Remove the use of `dev_err_probe(` in the resume ops. - Remove `MODULE_ALIAS(`. - Remove the vertical bar in bindings description paragraph. - Fix an error in the `pinctrl-0` parameter of the binding example, it was refering a node that wasn't existing. - Use uppercase pin names. - Link to v1: https://lore.kernel.org/r/20250225-hdp-upstream-v1-0-9d049c65330a@foss.st.com --- Clément Le Goffic (9): gpio: mmio: add BGPIOF_NO_INPUT flag for GPO gpiochip dt-bindings: pinctrl: stm32: Introduce HDP pinctrl: stm32: Introduce HDP driver MAINTAINERS: add Clément Le Goffic as STM32 HDP maintainer ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp13 ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp15 ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp25 ARM: dts: stm32: add alternate pinmux for HDP pin and add HDP pinctrl node ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp157c-dk2 board .../devicetree/bindings/pinctrl/st,stm32-hdp.yaml | 187 ++++++ MAINTAINERS | 6 + arch/arm/boot/dts/st/stm32mp131.dtsi | 7 + arch/arm/boot/dts/st/stm32mp15-pinctrl.dtsi | 25 + arch/arm/boot/dts/st/stm32mp151.dtsi | 7 + arch/arm/boot/dts/st/stm32mp157c-dk2.dts | 6 + arch/arm64/boot/dts/st/stm32mp251.dtsi | 7 + drivers/gpio/gpio-mmio.c | 11 +- drivers/pinctrl/stm32/Kconfig | 14 + drivers/pinctrl/stm32/Makefile | 1 + drivers/pinctrl/stm32/pinctrl-stm32-hdp.c | 720 +++++++++++++++++++++ include/linux/gpio/driver.h | 1 + 12 files changed, 991 insertions(+), 1 deletion(-) --- base-commit: a08b2b34239e63bd839078de98911d3653cdab83 change-id: 20250224-hdp-upstream-622e5da14a9f Best regards, -- Clément Le Goffic
