Support for odd resolutions / display timings
I have a bit of an odd display whose performance I've been trying to benchmark on different systems.
Its resolution is only 2560x1600 but I believe its EDID is inaccurate.
In testing with a Raspberry Pi, I have been able to find a set of hdmi_timings values that can be manually set in config.txt.
I have tried replicating these values with fbset on the RK3328-CC, but I got an error.
I am wondering if anyone has had success manually configuring an HDMI device, or could point me to the place where the different HDMI DMT modes are set?
I don't mind having to recompile the kernel to add support, but if that isn't necessary I would obviously prefer not to.
