SubjectRe: [PATCH 06/15] drm/rockchip: vop: limit resolution width to 3840

could you try to send the whole series to people? I only get this patch6
of a series of 15 and that is way confusing not knowing what you want
to actually achieve.

Hence I can also just point to rk3229, rk3328, rk3368 and rk3399 that
report a max output of 4096x2160 , which would be larger than that
3840 value?
