Add support for H96 Max V58: a compact TV box based on Rockchip RK3588 SoC [1] that ships with Android by default. Note that there is no publicly available hardware documentation, nor vendor sources to be used as a reference, so this implementation is best effort based on poking around my board and staring at the decompiled stock DTB. It works for me, but improvement suggestions are very much welcome. HDMI output is not tested, but expected to work. Auxiliary LED display is not enabled (no mainline driver available). The controller used is FD6551 connected to GPIO3 RK_PC7 (clk) and GPIO3 RK_PD0 (data), which happen to be the right pins for i2c5m0_xfer pinctrl config, and thus might potentially be used with the hardware I2C5 controller (to be verified). Out of tree drivers are available at [2] and another newer alternative at [3] SPDIF output tested using a 2-channel digital to analog converter box (higher channel counts not tested, but expected to work) [1] https://www.h96tvbox.com/product/h96max-v58/ [2] https://github.com/arthur-liberman/linux_openvfd/blob/master/driver/controllers/fd650.c [3] https://github.com/jefflessard/tm16xx-display Signed-off-by: Alexey Charkov <alchark@xxxxxxxxx> --- Changes in v2: - Added SPDIF support in SoC .dtsi files and board .dts - Fixed DT warnings found by Rob's bot - Reworded commit messages following Krzysztof's suggestion and collected his A-b - Link to v1: https://lore.kernel.org/r/20250106-rk3588-h96-max-v58-v1-0-d25255f851fc@xxxxxxxxx --- Alexey Charkov (3): dt-bindings: arm: rockchip: Add H96 Max V58 TV box arm64: dts: rockchip: Add SPDIF nodes to RK3588(s) device trees arm64: dts: rockchip: Add H96 Max V58 TV Box based on RK3588 SoC .../devicetree/bindings/arm/rockchip.yaml | 5 + arch/arm64/boot/dts/rockchip/Makefile | 1 + arch/arm64/boot/dts/rockchip/rk3588-base.dtsi | 64 ++ arch/arm64/boot/dts/rockchip/rk3588-extra.dtsi | 30 + .../arm64/boot/dts/rockchip/rk3588-h96-max-v58.dts | 826 +++++++++++++++++++++ 5 files changed, 926 insertions(+) --- base-commit: af349ca4d3f8659d84abc667125c826fda155109 change-id: 20240618-rk3588-h96-max-v58-c2c1bf8e6996 Best regards, -- Alexey Charkov <alchark@xxxxxxxxx>
