[PATCHv5 0/6] omapdrm: DSI command mode panel support

[Sebastian Reichel]

Hi,

Here is another round of the DSI command mode panel patchset
integrating the feedback from PATCHv4. The patches are based
on 4.20-rc1 + fixes from Laurent and Tony. I dropped the patches
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.

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 PATCHv4:
 * Apply Acked-/Tested-by received from Tony and Pavel
 * Fix spelling/wording in commit messagess
 * Use proper multi-line comments
 * Restructure patch 4: move the whole HDMI block into a
   static sub-function, 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
