* patch: kernel: rockchip-dev: Handle more resolutions with HDMI (β) The added patch add more PLL configurations, in order to satisfy more HDMI frequencies requirements. This should allow users to benefit from more resolutions. However, this is fairly untested. I only tested it on my 1080p screen and, yeah, it works but so does the kernel without this patch.

Anyway : The added patch add more PLL configurations, in order to satisfy more HDMI frequencies requirements. This should allow users to benefit from more resolutions. However, this is fairly untested. I only tested it on my 1080p screen and, yeah, it works but it also does without this patch. So could anyone test this with the following configurations ? * [ ] A HDMI 4K screen * [ ] A HDMI 1366x768 screen resolution * [ ] A VGA screen with a VGA to HDMI adapter * [ ] A DVI screen with a DVI to HDMI adapter Signed-off-by: Miouyouyou (Myy) <myy@miouyouyou.fr> * Using the patches provided by @Kwiboo for HDMI This provides me way more resolutions, including interlaced modes. I don't see 4K modes, though the screen attached can't do it, so I still don't know if that can help provided 4K modes on mainline kernels. Signed-off-by: Miouyouyou (Myy) <myy@miouyouyou.fr> * Support for 4K screens Using fixes provided by @czak Tested and approved by @czak too ! Signed-off-by: Miouyouyou (Myy) <myy@miouyouyou.fr>
