9f2231795b drm/omap: drop omapdss-boot-init
The table of compatible values needed to be prefixed with "omapdss,"
is empty, so all of this code is doing nothing now. Let's drop it.

e4869b048d drm/omap: dsi: drop custom panel capability support
Due to previous changes the DSI encoder gets the capabilities
via DSI client's mode_flags and no longer needs the omapdss
specific caps. The core code now checks if the DSI encoder
is actually configured into command mode instead of just checking
the panel capabilities.

e290c812eb drm/omap: dsi: Reverse direction of the DSS device enable/disable operations
Complete the direction reversal of the DSS device enable/disable
operations started by commit 19b4200d8f ("drm/omap: Reverse direction
of the DSS device enable/disable operations").

This effectively drops the requirement of calling DSS specific
code from the DSI panel driver moving it a bit further to a
standard drm_panel driver.

28d72874f8 drm/omap: dsi: drop virtual channel logic
This drops the virtual channel logic. Afterwards DSI clients
request their channel number and get the virtual channel with
the same number or -EBUSY if already in use.

The change here is not strictly speaking correct, as it combines the VC
(DSI's "configuration block") and virtual channel ID (the ID sent in the
DSI packets). But as we currently only support a single DSI command mode
panel, this works fine: we always use VC0, and VC ID 0.

This needs more work to support video mode panels, but that can be done
after moving to DRM bridge and panel model, after which we can do that
work with the proper APIs.

We can simplify this by making the core handle it automatically.

Move the drm_atomic_helper_legacy_gamma_set() functionality into
drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use
drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.

c67e62790f drm/prime: split array import functions v4
Mapping the imported pages of a DMA-buf into an userspace process
doesn't work as expected.

But we have reoccurring requests on this approach, so split the
functions for this and  document that dma_buf_mmap() needs to be used
instead.

v2: split it into two functions
v3: rebased on latest changes
v4: update commit message a bit

fd4e788e97 drm/omap: sdi: fix bridge enable/disable
When the SDI output was converted to DRM bridge, the atomic versions of
enable and disable funcs were used. This was not intended, as that would
require implementing other atomic funcs too. This leads to:

WARNING: CPU: 0 PID: 18 at drivers/gpu/drm/drm_bridge.c:708 drm_atomic_helper_commit_modeset_enables+0x134/0x268

and display not working.

Fix this by using the legacy enable/disable funcs.

a5d704d332 drm/omap: Fix runtime PM imbalance on error
pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of its
direct wrappers in omapdrm assume that PM usage counter will
not change on error. Thus a pairing decrement is needed on
the error handling path for these wrappers to keep the counter
balanced.

1b409fda60 drm: omapdrm: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.
