Hey Heiko, I have tested your series and it successfully fixes the problem with the 2nd camera when HDMI is connected at boot. Besides that the patch looks good and my tests have confirmed that both cameras have the same output quality when I exchange the connected ISP instances.

The rk3399 has two ISPs and right now only the first one is usable. The second ISP is connected to the TXRX dphy on the soc. The phy of ISP1 is only accessible through the DSI controller's io-memory, so this series adds support for simply using the dsi controller is a phy if needed. That solution is needed at least on rk3399 and rk3288 but no-one has looked at camera support on rk3288 at all, so right now only implement the rk3399 specifics. changes in v2: - enable grf-clock also for init callback to not break if for example hdmi is connected on boot and disabled the grf clock during its probe - add Sebastian's Tested-by - add Rob's Ack for the phy-cells property Heiko Stuebner (6): drm/rockchip: dsi: add own additional pclk handling dt-bindings: display: rockchip-dsi: add optional #phy-cells property drm/rockchip: dsi: add ability to work as a phy instead of full dsi arm64: dts: rockchip: add #phy-cells to mipi-dsi1 arm64: dts: rockchip: add cif clk-control pinctrl for rk3399 arm64: dts: rockchip: add isp1 node on rk3399 .../display/rockchip/dw_mipi_dsi_rockchip.txt | 1 + arch/arm64/boot/dts/rockchip/rk3399.dtsi | 39 ++ drivers/gpu/drm/rockchip/Kconfig | 2 + .../gpu/drm/rockchip/dw-mipi-dsi-rockchip.c | 349 ++++++++++++++++++ 4 files changed, 391 insertions(+) -- 2.29.2
