This adds support for RZ/T2H pinctrl and gpio The basic GPIO tests have been done on the RZ/T2H Evaluation Board. More pinctrl tests will come with a further patchset that enables peripherals using pinctrl modes. - GPIO writes: (User led Green 1) gpioset P23_1=1 (User led Green 2) gpioset P32_2=1 (User led Yellow) gpioset P6_7=1 For GPIO reads, used the CN49 connector; Connect pin10 to pin11 (ground) gpioget P9_1 "P9_1"=inactive Connect pin10 to pin12 (3v3) gpioget P9_1 "P9_1"=inactive This patchset applies on top of patchset [1] [1]: https://lore.kernel.org/linux-renesas-soc/20250515141828.43444-1-thierry.bultel.yh@xxxxxxxxxxxxxx/T/#t Thierry Bultel (3): dt-bindings: pinctrl: add compatible for Renesas RZ/T2H Add the pinctrl and gpio driver for RZ/T2H arm64: dts: renesas: Add pinctrl for renesas RZ/T2H SoC .../bindings/pinctrl/renesas,pfc.yaml | 59 +- arch/arm64/boot/dts/renesas/r9a09g077.dtsi | 9 + drivers/pinctrl/renesas/Kconfig | 13 + drivers/pinctrl/renesas/Makefile | 1 + drivers/pinctrl/renesas/pinctrl-rzt2h.c | 783 ++++++++++++++++++ include/dt-bindings/pinctrl/rzt2h-pinctrl.h | 23 + 6 files changed, 871 insertions(+), 17 deletions(-) create mode 100644 drivers/pinctrl/renesas/pinctrl-rzt2h.c create mode 100644 include/dt-bindings/pinctrl/rzt2h-pinctrl.h -- 2.43.0
