This patchset is the follow-up the v4 patchset from Benoit Parrot at [1]. This patch series adds virtual-plane support to omapdrm driver to allow the use of display wider than 2048 pixels. In order to do so we introduce the concept of hw_overlay which can then be dynamically allocated to a plane. When the requested output width exceed what be supported by one overlay a second is then allocated if possible to handle display wider then 2048. This series replaces an earlier series which was DT based and using statically allocated resources. This implementation is inspired from the work done in msm/disp/mdp5 driver.
I think this looks good. I'll apply this to my work tree to see if I see any issues during my daily work, and if not, I'll push to drm-misc-next.
Have you tested this with other platforms than x15? I'm mostly thinking about omap3/4, as the DSS is somewhat different on those platforms.
