Add the basic support for the board. (Not officially released yet) It is based on the Rockchip rk3576 SoC, so I haven't added the following devices yet: - VOP/HDMI - UFS as the support for those has not been merged yet, but are close to be and I already validated that they work. It will come with another patch set. The following devices are supported and working: - UART - SD Card - Ethernet - USB - RTC Changes since v1: - Add missing dt bindings - Remove clock-frequency in rtc node - Add line break in pmic pinctrls Detlev Casanova (1): dt-bindings: arm: rockchip: Add Radxa ROCK 4D board Stephen Chen (1): arm64: dts: rockchip: Add Radxa ROCK 4D device tree .../devicetree/bindings/arm/rockchip.yaml | 5 + arch/arm64/boot/dts/rockchip/Makefile | 1 + .../boot/dts/rockchip/rk3576-rock-4d.dts | 651 ++++++++++++++++++ 3 files changed, 657 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3576-rock-4d.dts -- 2.48.1
