Some SoC without MMU have display driver where a drm/kms driver
could be implemented.
Before doing such kind of thing drm/kms must allow to use mmuless devices.
This patch propose to remove MMU configuration flag and add a cma helper
function to help implementing mmuless display driver
version 4:
- add documentation about drm_gem_cma_get_unmapped_area()
- stub it MMU case

Backmerge the docs-next branch from Jon into drm-misc so that we can
apply the dma-buf documentation cleanup patches. Git found a conflict
where there was none because both drm-misc and docs had identical
patches to clean up file rename issues in the rst include directives.

Adds files and directories to debugfs for controlling and reading frame
CRCs, per CRTC:
dri/0/crtc-0/crc
dri/0/crtc-0/crc/control
dri/0/crtc-0/crc/data
Drivers can implement the set_crc_source callback() in drm_crtc_funcs to
start and stop generating frame CRCs and can add entries to the output
by calling drm_crtc_add_crc_entry.
v2:
- Lots of good fixes suggested by Thierry.
- Added documentation.
- Changed the debugfs layout.
- Moved to allocate the entries circular queue once when frame
generation gets enabled for the first time.
v3:
- Use the control file just to select the source, and start and stop
capture when the data file is opened and closed, respectively.
- Make variable the number of CRC values per entry, per source.
- Allocate entries queue each time we start capturing as now there
isn't a fixed number of CRC values per entry.
- Store the frame counter in the data file as a 8-digit hex number.
- For sources that cannot provide useful frame numbers, place
XXXXXXXX in the frame field.
v4:
- Build only if CONFIG_DEBUG_FS is enabled.
- Use memdup_user_nul.
- Consolidate calculation of the size of an entry in a helper.
- Add 0x prefix to hex numbers in the data file.
- Remove unnecessary snprintf and strlen usage in read callback.
v5:
- Made the crcs array in drm_crtc_crc_entry fixed-size
- Lots of other smaller improvements suggested by Emil Velikov
v7:
- Move definition of drm_debugfs_crtc_crc_add to drm_internal.h
v8:
- Call debugfs_remove_recursive when we fail to create the minor
device
v9:
- Register the debugfs directory for a crtc from
drm_crtc_register_all()
v10:
- Don't let debugfs failures interrupt CRTC registration (Emil
Velikov)
v11:
- Remove extra brace that broke compilation. Sorry!

drm: Reject page_flip for !DRIVER_MODESET
so as a result of moving the page_flip ioctl, this fix has
been rolled into this patch.
Signed-off-by: Sean Paul <seanpaul@chromium.org>
Just for the struct drm_mode_object base class. The header file was
already partially extracted to help untangle the include loops.
v2:
- Also move the generic get/set property ioctls. At first this seemed
like a bad idea since it requires making drm_mode_crtc_set_obj_prop
non-static. But eventually that will get split away too (like
the connector version already is) for both crtc and planes. Hence I
reconsidered.
- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
renaming the drm_modeset.h header I already started building up.
This is more consistent (matches the name of the main structure),
and I want to be able to use drm_modeset.[hc] for the basic modeset
init/cleanup functionality like drm_mode_config_init.
