c8da819478 drm/stm: move enable/disable_vblank to crtc 
enable/disable_vblank() functions at drm_driver level
are deprecated. Move them to the ltdc drm_crtc_funcs
structure.

879659bb87 drm/stm: check pitch and size calculations even if !CONFIG_MMU 
In all cases we have to check pitch and size calculations to speed up
data transfer.

21f815bf77 drm/stm: drv: Improve data transfers 
To optimize data transfers, align pitch on 128 bytes & height
on 4 bytes. This optimization is not applicable on hw without MMU.

068b393c1a drm/stm: Use drm_fb_cma_fbdev_init/fini() 
Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on
the fact that drm_device holds a pointer to the drm_fb_helper structure.
This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.
Remove duplicate ldev assignment.

4930a4334e drm/stm: Use drm_gem_fb_create() 
drm_fb_cma_create() is just a wrapper around drm_gem_fb_create() now,
so use the function directly.

58ba9aabb8 drm/stm: Use .dumb_map_offset and .dumb_destroy defaults 
This driver can use the drm_driver.dumb_destroy and
drm_driver.dumb_map_offset defaults, so no need to set them.

af5125de7a drm/stm: drv: Rename platform driver name 
Rename the platform driver name from "stm" to "stm32-display"
for a better readability in /sys/bus/platform/drivers entries.

Note: We keep "stm" as drm_driver.name because it is better
when using "modetest -M stm ..." (even if recent modetest patch
avoids using -M).
