This adds a pin control driver created by Emil for the T-Head TH1520 RISC-V SoC used on the Lichee Pi 4A and BeagleV Ahead boards and updates the device trees to make use of it. Changes in v3: - Add Rb from Rob for the binding - Rebase on 6.12-rc1 which enables AP_SUBSYS clock controller in dts - Update dts to use AP_SUBSYS clock controller instead of fixed clocks - Remove unneeded defines from the driver for dt unit addresses - Link to v2: https://lore.kernel.org/linux-riscv/20240914-th1520-pinctrl-v2-0-3ba67dde882c@xxxxxxxxxxxxxxx/ Changes in v2: - Add thead,pad-group device tree property - Change driver to use the thead,pad-group property instead of the unit address to identify the pad group of the pin controller being probed - Return -EINVAL if no pin group can be determined during probe. In v1, there was a bug that instead returned an unitialized variable - Link to v1: https://lore.kernel.org/r/20240902-th1520-pinctrl-v1-0-639bf83ef50a@xxxxxxxxxxxxxxx Signed-off-by: Drew Fustini <dfustini@xxxxxxxxxxxxxxx> --- Emil Renner Berthing (8): dt-bindings: pinctrl: Add thead,th1520-pinctrl bindings pinctrl: Add driver for the T-Head TH1520 SoC riscv: dts: thead: Add TH1520 pin control nodes riscv: dts: thead: Add TH1520 GPIO ranges riscv: dts: thead: Adjust TH1520 GPIO labels riscv: dts: thead: Add Lichee Pi 4M GPIO line names riscv: dts: thead: Add TH1520 pinctrl settings for UART0 riscv: dtb: thead: Add BeagleV Ahead LEDs .../bindings/pinctrl/thead,th1520-pinctrl.yaml | 176 ++++ MAINTAINERS | 2 + arch/riscv/boot/dts/thead/th1520-beaglev-ahead.dts | 87 ++ .../boot/dts/thead/th1520-lichee-module-4a.dtsi | 43 + arch/riscv/boot/dts/thead/th1520-lichee-pi-4a.dts | 28 + arch/riscv/boot/dts/thead/th1520.dtsi | 65 +- drivers/pinctrl/Kconfig | 13 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-th1520.c | 907 +++++++++++++++++++++ 9 files changed, 1306 insertions(+), 16 deletions(-) --- base-commit: 9852d85ec9d492ebef56dc5f229416c925758edc change-id: 20240930-th1520-pinctrl-d42163ea2c11 Best regards, -- Drew Fustini <dfustini@xxxxxxxxxxxxxxx>
