[PATCH v3 0/9] drm/msm/dpu: be more friendly to X.org

[Dmitry Baryshkov]

Unlike other compositors X.org allocates a single framebuffer covering
the whole screen space. This is not an issue with the single screens,
but with the multi-monitor setup 5120x4096 becomes a limiting factor.
Check the hardware-bound limitations and lift the FB max size to
16383x16383.
