Earlier kernels showed a corrupt image on hdmi, on v4.16 things work fine at resolutions up to 1920x1080. On v4.17-rc2 two fixes are pending for hdmi to work: 1) "iommu/rockchip: make clock handling optional" https://patchwork.kernel.org/patch/10344875/ 2) Add missing enable_irq in rockchip_drm_vop.c http://lists.infradead.org/pipermail/linux-rockchip/2018-April/020427.html These should get merged soon, so I think it's time to enable the hdmi output in our dts.
