b79fe9abd5 drm/fbdev-dma: Implement fbdev emulation for GEM DMA helpers 
Implement fbdev emulation that is optimized for drivers that use
DMA helpers. The buffers may no tbe moveable, may not require damage
handling and have to be located in system memory. This allows fbdev
emulation to operate directly on the buffer and mmap it to userspace.

Besides those constraints, the emulation works like in the generic
code. As an internal DRM client provides, it receives hotplug, restore
and unregister events. The DRM client is independent from the fbdev
probing, which runs on the first successful hotplug event.

The emulation is part of the DMA helper module and not build unless
DMA helpers and fbdev emulation has been configured.

Tested with vc4.

03e7ac67e7 drm/cirrus: Enable damage clipping on primary plane 
Enable damage clipping on the primary plane and iterate over small
areas of reported framebuffer damage. Avoid the overhead of permanent
full-screen updates that cirrus currently implements.

This problem is indicated by the warning

  drm_plane_enable_fb_damage_clips() not called

in the kernel's log. Without damage clipping, drivers do full updates
of the screen area. This is costly as many screen updates, such as
cursor movement or command-line input, only change a small portion
of the output. Damage clipping allows renderers to inform drivers about
the changed areas.

With the damage information known, cirrus now iterates over a list of
change areas and only flushes those to the hardware's scanout buffer.

d99c028941 drm/cirrus: Convert to regular atomic helpers 
Replace simple-KMS helpers with DRM's regular helpers for atomic
modesetting. Avoids the mid-layer and the additional wrappers around
GEM's shadow-plane helpers.

Most of the simple-KMS code is just wrappers around regular atomic
helpers. The conversion is therefore equivalent to pulling the
simple-KMS helpers into cirrus and removing all the intermediate
code and data structures between the driver and the atomic helpers.
As the simple-KMS helpers lump primary plan, CRTC and encoder into a
single data structure, the conversion to regular helpers allows to
split modesetting from plane updates and handle each individually.

e049497702 drm/cirrus: Integrate connector into pipeline code 
Integrate the connector with the rest of the pipeline setup code.
Move some helpers within the file and adapt naming slightly. No
functional changes.

Done in preparation of converting cirrus to regular atomic helpers.

d2ff2ef8c0 drm/cirrus: Split cirrus_mode_set() into smaller functions 
Split cirrus_mode_set() into smaller functions that set the display
mode, color format and scnaline pitch individually. Better reflects
the design of the DRM modesetting pipeline.

Done in preparation of converting cirrus to regular atomic helpers.

2fb82d5a42 drm/cirrus: Move drm_dev_{enter, exit}() into DRM helpers 
Call drm_dev_enter() and drm_dev_exit() immediately after entering
cirrus' DRM helper functions. Remove these calls from other functions.
Each enter/exit block in the DRM helpers covers the full hardware
update. No functional changes.

cc158d0e9b drm/cirrus: Use drm_fb_blit() to update scanout buffer 
Cirrus' blit helper reimplements code from the shared blit helper

d1c0cc8d0d drm/cirrus: Compute blit destination offset in single location 
The calculation for the scanout-buffer blit offset is independent
from the color format. In the one case where the current code uses
fb->pitches[0] instead of cirrus->pitch, their values are identical.
Hence merge all into a single line.

3e853b9f89 drm/format-helper: Make conversion_buf_size() support sub-byte pixel fmts 
There are DRM fourcc formats that have pixels smaller than a byte, but the
conversion_buf_size() function assumes that pixels are a multiple of bytes
and use the struct drm_format_info .cpp field to calculate the dst_pitch.

Instead, calculate it by using the bits per pixel (bpp) and divide it by 8
to account for formats that have sub-byte pixels.

for example, the user pressing CTRL-C. That may happen if eviction
