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.
Changes since v4 at [1]:
- rebased on v5.15-rc2
What is this based on? Doesn't apply to v5.15-rc2, and "error: sha1 information is lacking or useless".
Indeed the sha1 info is useless, it's based on v5.15-rc2 on top of "HACK: drm/omap: increase DSS5 max tv pclk to 192MHz"
in order to validate on 2k monitors.
I'm personally fine with removing the HACK from that, and applying it
too. I used the patch for a long time without any issues. However, I
never found anyone to confirm that 192MHz is fine (or that it's not
fine). Too old HW for finding HW engineers to look at it =).
