The current driver calls drm_bridge_add(), to add the dsi bridge
to the global bridge list, in dw_mipi_dsi_host_attach().
Thus, it relies on the probing of panel or bridge sub-nodes to
trigger the execution of dsi host attach() that will, in turn,
call dw_mipi_dsi_host_attach().
This causes an

The panel is able to receive commands in LP. The current hack to
force backlight commands in HS was due to workaround an incorrect

video out was active.

No driver implements FBIOSCURSOR, so this function has no purpose
and can be removed. Apparently it was added in linux-2.1.44 to handle
compatibility for drivers/sbus/char/sunfb.c but lost its purpose when
that driver got rewritten in linux-2.5.63.

The fbdev code uses compat_alloc_user_space in a few of its

The big change is device_add so that device_del can auto-cleanup
devres resources. This allows us to use devm_drm_dev_alloc, which
removes the last user of drm_dev_init.

v3: use devres_open/release_group so we can use devm without real

Just some prep work before we rework the lifetime handling, which

Currently a null pointer check on pointer mode is passing mode to
function drm_mode_vrefresh and this causes a null pointer dereference

When we swapout/in a BO we try to change the caching
attributes of the pages before/after doing the copy.
On x86 this is done by calling set_pages_uc(),
set_memory_wc() or set_pages_wb() for not highmem pages
to update the linear mapping of the page.
On all other platforms we do exactly nothing.
map_page_into_agp() and unmap_page_from_agp() are only defined on x86.
On all other platforms they are defined as noops. So this code doesn't has any
effect at all.
