Changes since v5:
- Add Add Reviewed-by: from Rob Herring <robh@kernel.org> and
  Benoit Parrot <bparrot@ti.com> to binding patches
- Color property changes and fixes to the driver implementation patch
  - Check CTM and gamma support from dispc_features when creating crtc
  - Implement CTM support for k2g and fix k3 CTM implementation
  - Remove gamma property persistence and always write color properties
    in a new modeset

Changes since v4:
- itemize named resource property descriptions in dt binding
- fix wp to wb in the ti,j721e-dss reg property description
- remove fifo underflow irq handling, it is not an error and
  it should be used for debug purposes only
- memory tuning, prefetch plane fifo up to high-threshold value to
  minimize possibility of underflows.

Changes since v3:
- Add descriptions some yaml binding properites
- Remove redundant minItems directives from yaml bindings
- Remove ports node from ti,k2g-dss yaml binding
- no change to MAINTAINERS or to the driver code

Changes since v2:
- Add version history to commit messages
- Fix yaml bindings now that got dt_binding_check dtbs_check working propery
- Move tidss entry in MAINTAINERS after omapdrm and add "T: git
  git://anongit.freedesktop.org/drm/drm-misc"
- no change to driver code

Changes since the first version of the patch series [2]:
- "drm/tidss: New driver for TI Keystone platform Display SubSystem"
 - rebased on top of drm-next-2019-11-27
 - sort all include lines in all files
 - remove all include <drm/drmP.h>
 - remove select "select VIDEOMODE_HELPERS"
 - call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no
   to call it in new modeset case as it is also called in vp_enable())
 - change probe sequence and drm_device allocation (follow example in drm_drv.c)
 - use __maybe_unused instead of #ifdef for pm functions
 - remove "struct drm_fbdev_cma *fbdev;" from driver data
 - check panel connector type before connecting it
- No change to binding or MAINTAINERS patches

There was couple of attempts upstream an earlier version of this
driver about a year ago [1]. Back then I needed to stop my efforts to
implement support for next Keystone DSS version, so now the driver
supports three different Keystone DSS version on three different SoCs.

I am starting the patch series versioning from the beginning because it
has been over a year since the previous patch set and the structure of
the driver has evolved quite a bit. However, all the earlier comments
should be addressed in this series.
