Hi,
Here is another round of the DSI command mode panel patchset
integrating the feedback from PATCHv5. The patches are based
on Tomi's omapdrm-5.2 tag. It does not contain the patches
required for OMAP3 support (it needs a workaround for a hardware
bug) and for automatic display rotation. They should get their
own series, once this patchset has landed. Also it does not
yet use the DRM panel/bridge things, but IMHO should be merged
before. Having this helps means 'git bisect' can be used while
converting DSI support to DRM panel/bridge style.
Tested on Droid 4:
* Framebuffer Console, updated at 1Hz due to blinking cursor
* Display blanking
* Xorg 1.19 with modesetting driver
* Weston 5.0 with DRM backend
* kmstest (static image)
* No updates send when nothing needs to be sent
Known issues:
* OMAP3 is untested and most likely broken due to missing
workaround(s) for hardware bugs.
* Weston 5.0 with fbdev backend does not work, since it
uses neither page flip nor dirty ioctl. You need to use
the drm backend.
Changes since PATCHv5:
* Rebased to Tomi's omapdrm-5.2 tag
* Simplified omap_framebuffer_dirty() by using
drm_for_each_crtc()
Changes since PATCHv4:
* Apply Acked-/Tested-by received from Tony and Pavel
* Fix spelling/optimize commit messages
* Use proper multi-line comments
* Restructure patch 4: move the whole HDMI block into a
static subfunction, that is only called when output
type is HDMI. Also drop the incorrect check for DVI.
Changes since PATCHv3:
* Drop all Tested/Acked-by tags
* Drop the rotation patches for now
* Rebase to 4.20-rc1 + fixes from Laurent and Tony
* Add fixes for DSI regressions introduced in 4.20-rc1
* Store info update manual update mode in omap_crtc_state
* Lock modesetting in omap_framebuffer_dirty
* Directly loop through CRTCs instead of connectors in dirty function
* Properly refresh display during page flips and get Weston working
* Add more comments about implementation details
Changes since PATCHv2:
* Drop omap3 quirk patch (OMAP3 should get its own mini-series)
* Rebase to current linux-next
* Use existing 'rotation' DT property to set DRM orientation hint
* Add Tested-by from Tony
Changes since PATCHv1:
* Drop patches, that were queued by Tomi
* Rebase to current master
* Rework the omap3 workaround patch to only affect omap3
* Add orientation DRM property support
