HW I’m using is vontar rk3528 tvbox. So far - on mainline 6.10 kernel - I got working: clocks, pin control, uart, sdcard, eth, usb. I started to work on dw hdmi and got to stage with correct mode sets by dw-hdmi but I stuck with vop3 support. Generally - I was back porting code from bsp but rockchip bsp is too divergent from mainline to my back porting skills :-( If anybody can help with vop3 - then we can have quite good initial support of rk3528 in mainline (the, sdcard, usb, eth, hdmi) gpu, hdmi audio should be probably easy… My rk3528 enablements: Bindings: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1100-dt-bindings-clock-add-rk3528-clock-definitions.patch Clocks: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1101-clk-rockchip-add-clock-controller-for-the-RK3528.patch Pincontrol: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1102-pinctrl-rockchip-add-rk3528-support.patch Power domain bindings: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1103-dt-bindings-power-add-RK3528-SoCs-header-for-idle.patch Ethernet support: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1104-ethernet-stmmac-dwmac-rk3528-add-GMAC-support.patch Power domains support: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1105-soc-rockchip-power-domain-add-rk3528-support.patch usb: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1106-phy-rockchip-inno-usb2-add-phy-support-for-rk3528.patch SoC power domains: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1108-soc-rockchip-power-domain-add-rk3528-support.patch Thermal: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1108-thermal-rockchip-add-support-for-rk3528.patch Naneng phy: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1109-phy-rockchip-naneng-combphy-add-support-for-rk3528.patch dw hdmi: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1110-phy-rockchip-inno-hdmi-add-support-for-rk3528.patch Inno hdmi: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1111-drm-rockchip-dw_hdmi-add-support-for-rk3528.patch Nvmem: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1113-nvmem-rockchip-otp-add-support-for-rk3528.patch Sound soc: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1114-sound-soc-codecs-add-rk3528-support.patch rk3528 dtsi: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1150-arm64-dtsi-rockchip-add-3528.dtsi.patch: Vontar tvbox dts: https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.10/files/1151-arm64-dts-rockchip-add-dts-for-vontar_r3.patch It may happen that above patches will not apply clean on vanilla 6.10 as I’m patching kernel for s905/s912/sm1/g12/rpi3/rpi4/rpi5/3328/3399//3566/3568/3588/3528 and rk3528 patches are after applied s905/s912/sm1/g12/rpi3/rpi4/rpi5/3328/3399/3566/3568/3588 patches.
