Markus Elfring e9635133d4 drm/sti: Replace 17 seq_puts() calls by seq_putc()
Single characters should be put into a sequence at several places.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

Fabien Dessenne f766c6c810 drm/sti: use valid video mode
In atomic mode the crtc_xxx (eg crtc_hdisplay) members of the mode
structure may be unset before calling atomic_check/commit for planes.
Instead of, use xxx members which are actually set.

Benjamin Gaignard 83af0a483a drm: sti: use late_register and early_unregister callbacks
Make sti driver use register callback to move debugfs
initialization out of sub-components creation.
This will allow to convert driver .load() to
drm_dev_alloc() and drm_dev_register().

sti_compositor bring up 2 crtc but only one debugfs init is
needed so use drm_crtc_index to do it on the first one.
This can't be done in sti_drv because only sti_compositor have
access to the devices.
It is almost the same for sti_encoder which handle multiple
encoder while one only debugfs entry is needed so add a boolean
to avoid multiple debugfs initialization

Arnd Bergmann 0f3e15618d drm/sti: include linux/seq_file.h where needed
The sti drm driver has a lot of debugfs interface that cause
build errors in some configurations when seq_file.h is not
included implicitly:

drm/sti/sti_mixer.c: In function 'mixer_dbg_ctl':
drm/sti/sti_mixer.c:88:2: error: implicit declaration of function 'seq_puts' [-Werror=implicit-function-declaration]
drm/sti/sti_mixer.c:91:4: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
drm/sti/sti_gdp.c: In function 'gdp_dbg_ctl':
drm/sti/sti_gdp.c:146:2: error: implicit declaration of function 'seq_puts' [-Werror=implicit-function-declaration]
drm/sti/sti_gdp.c:149:4: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
drm/sti/sti_gdp.c: In function 'gdp_dbg_show':
drm/sti/sti_gdp.c:208:32: error: dereferencing pointer to incomplete type 'struct seq_file'

This adds an explicit #include statement in all of the affected files.

Vincent Abriou 29d1dc62e1 drm/sti: atomic crtc/plane update
Better fit STI hardware structure.
Planes are no more responsible of updating mixer information such
as z-order and status. It is now up to the CRTC atomic flush to
do it. Plane actions (enable or disable) are performed atomically.
Disabling of a plane is synchronize with the vsync event.

Vincent Abriou 871bcdfea6 drm/sti: code clean up
Purpose is to simplify the STI driver:
- remove layer structure
- consider video subdev as part of the compositor (like mixer subdev)
- remove useless STI_VID0 and STI_VID1 enum

Benjamin Gaignard cfd8d744fe drm: sti: add VID layer
VIDeo plug are one of the compositor input sub-devices.
VID are dedicated to video inputs like YUV plans.

Like GDP, VID are part of Compositor hardware block
and use sti_layer structure to provide an abstraction for
Compositor calls.
