Unlike the existing driver (gpio-rtd.c) which uses shared bank registers, the RTD1625 features a per-pin register architecture where each GPIO line is managed by its own dedicated 32-bit control register. This distinct hardware design requires a new, separate driver. To accommodate this, we extend the gpio-regmap core framework to handle per-pin register operations, write-enable mechanisms, and add custom set_config callback. Best Regards, Yu-Chun Lin --- Changes in v3: patch 1 (gpio: Replace "default y" with "default ARCH_REATLEK" in Kconfig): - Chang "remove default y" to "replace it with default ARCH_REALTEK". patch 2 (gpio: regmap: add gpio_regmap_get_gpiochip() accessor): - New patch patch 3 (gpio: regmap: Add gpio_regmap_operation and write-enable support): - New patch - Update all drivers utilizing the gpio-regmap framework to accommodate the new reg_mask_xlate function signature. patch 4 (gpio: regmap: Add set_config callback): - New patch patch 5 (dt-bindings: gpio: realtek: Add realtek,rtd1625-gpio): - Remove description for reg. - Add Reviewed-by tag from Krzysztof. patch 6 (gpio: realtek: Add driver for Realtek DHC RTD1625 SoC): - Refactor to utilize the gpio-regmap framework. - Create a custom irqdomain. patch 7(arm64: dts: realtek: Add GPIO support for RTD1625): - Add Reviewed-by tag from Bartosz. v2: https://lore.kernel.org/lkml/20260408025243.1155482-1-eleanor.lin@realtek.com/ v1: https://lore.kernel.org/lkml/20260331113835.3510341-1-eleanor.lin@realtek.com/ Tzuyi Chang (2): dt-bindings: gpio: realtek: Add realtek,rtd1625-gpio gpio: realtek: Add driver for Realtek DHC RTD1625 SoC Yu-Chun Lin (5): gpio: Replace "default y" with "default ARCH_REALTEK" in Kconfig gpio: regmap: add gpio_regmap_get_gpiochip() accessor gpio: regmap: Add gpio_regmap_operation and write-enable support gpio: regmap: Add set_config callback arm64: dts: realtek: Add GPIO support for RTD1625 .../bindings/gpio/realtek,rtd1625-gpio.yaml | 71 ++ arch/arm64/boot/dts/realtek/kent.dtsi | 39 ++ drivers/gpio/Kconfig | 15 +- drivers/gpio/Makefile | 1 + drivers/gpio/gpio-104-idi-48.c | 18 +- drivers/gpio/gpio-i8255.c | 13 +- drivers/gpio/gpio-idio-16.c | 16 +- drivers/gpio/gpio-max7360.c | 10 + drivers/gpio/gpio-pcie-idio-24.c | 15 +- drivers/gpio/gpio-regmap.c | 80 ++- drivers/gpio/gpio-rtd1625.c | 608 ++++++++++++++++++ drivers/iio/adc/ad7173.c | 32 +- drivers/iio/addac/stx104.c | 17 +- drivers/pinctrl/bcm/pinctrl-bcm63xx.c | 12 +- drivers/pinctrl/pinctrl-tps6594.c | 10 + include/linux/gpio/regmap.h | 51 +- 16 files changed, 963 insertions(+), 45 deletions(-) create mode 100644 Documentation/devicetree/bindings/gpio/realtek,rtd1625-gpio.yaml create mode 100644 drivers/gpio/gpio-rtd1625.c -- 2.34.1
