Currently the switch statement for format->cpp[0] value 4 assigns
color_index which is never read again and then falls through to the
default case and returns. This looks like a missing break statement

ef54569966 drm/ast: remove duplicate assignment of ast_crtc_funcs member
The struct member 'set_config' was assigned twice:

static const struct drm_crtc_funcs ast_crtc_funcs = {
	.reset = ast_crtc_reset,
	.set_config = drm_crtc_helper_set_config,
	......
	.set_config = drm_atomic_helper_set_config,

};

Since the second one is which we use now in fact, we can remove the
first one.

This fixes the following coccicheck warning:

f0adbc382b drm/ast: Allocate initial CRTC state of the correct size
The ast driver inherits from DRM's CRTC state, but still uses the atomic
helper for struct drm_crtc_funcs.reset, drm_atomic_helper_crtc_reset().

The helper only allocates enough memory for the core CRTC state. That
results in an out-ouf-bounds access when duplicating the initial CRTC
state. Simplified backtrace shown below:

80f7c3f776 drm/vram: Add helpers to validate a display mode's memory requirements
Devices with low amount of dedicated video memory may not be able
to use all possible display modes, as the framebuffers may not fit
into VRAM. The new helper function drm_vram_helper_mode_valid()
implements a simple test to sort out all display modes that can
not be used in any case. Drivers should call this function from
struct drm_mode_config_funcs.mode_valid.

The functionality was originally implemented by the ast driver, which
is being converted as well.

a4d46a8e26 drm/vram-helper: Remove BO device from public interface
TTM is an implementation detail of the VRAM helpers and therefore
shouldn't be exposed to the callers. There's only one correct value
for the BO device anyway, which is the one stored in the DRM device.

So remove struct ttm_bo_device from the VRAM-helper interface and
use the device's VRAM manager unconditionally. The GEM initializer
function fails if the VRAM manager has not been initialized.

3339fdf574 drm/ast: Store primary-plane format in struct ast_crtc_state
Reading the primary plane's framebuffer from the CRTC's atomic_flush()
function is fragile as the plane state or framebuffer can be NULL.
Instead, we let the plane's atomic_check() store the framebuffer format
in the CRTC state. The CRTC always receives the framebuffer format that
is currently programmed, or NULL if no mode has been set yet.

The STR is

	* wake up the display by pressing a key

CRTC modesetting depends on the new state of the CRTC and the primary
plane's framebuffer. The bugfix moves the modesetting code into the
CRTC's atomic_flush() function, where it is protected from the plane's
framebuffer being NULL.

The CRTC's atomic-enable function, which is the modesetting's original
location, still contains DPMS state handling. It's exactly the inverse
of the atomic-disable function.

v3:
	* protect modesetting from from fb == NULL
v2:
	* do an atomic check for plane
	* reject invisible primary planes

2f5989fcd1 drm/ast: Move cursor update code to ast_show_cursor()
A call to ast's show-cursor function now receives the cursor image
and updates the buffer. The change splits off image update and
base-address update into separate functions.

v3:
	* move ast_{show,hide}_cursor() in a previous patch

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  It's also pretty large in commit count and new amd header file size.
  The largest thing is four new amdgpu products (navi12/14, arcturus and
  renoir APU support).

  Otherwise it's pretty much lots of work across the board, i915 has
  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework
  (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been

8a99de3dc0 drm/ast: Replace struct ast_fbdev with generic framebuffer emulation
This patch replaces ast's framebuffer console with DRM's generic
implememtation. All respective code is being removed from the driver.

The console is set up with a shadow buffer. The actual buffer object is
not permanently pinned in video ram, but just another buffer object that
the driver moves in and out of vram as necessary. The driver's function
ast_crtc_do_set_base() used to contain special handling for the framebuffer
console. With the new generic framebuffer, the driver does not need this
code an longer.

81da87f63a drm: Replace drm_gem_vram_push_to_system() with kunmap + unpin
The push-to-system function forces a buffer out of video RAM. This decision
should rather be made by the memory manager. By replacing the function with
calls to the kunmap and unpin functions, the buffer's memory becomes available,
but the buffer remains in VRAM until it's evicted by a pin operation.

This patch replaces the remaining instances of drm_gem_vram_push_to_system()
in ast and mgag200, and removes the function from DRM.

5b24f71504 drm: Reserve/unreserve GEM VRAM BOs from within pin/unpin functions
The original bochs and vbox implementations of pin and unpin functions
automatically reserved BOs during validation. This functionality got lost
while converting the code to a generic implementation. This may result
in validating unlocked TTM BOs.

Adding the reserve and unreserve operations to GEM VRAM's pin and unpin
functions fixes the bochs and vbox drivers. Additionally the patch changes
the mgag200, ast and hibmc drivers to not reserve BOs by themselves.

376bc02da2 drm/ast: Replace ttm_bo_unref with ttm_bo_put
The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.

A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.

fcd70cd36b drm: Split out drm_probe_helper.h
Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

5478ad10e7 drm/ast: Remove existing framebuffers before loading driver
If vesafb attaches to the AST device, it configures the framebuffer memory
for uncached access by default. When ast.ko later tries to attach itself to
the device, it wants to use write-combining on the framebuffer memory, but
vesefb's existing configuration for uncached access takes precedence. This
results in reduced performance.

Removing the framebuffer's configuration before loding the AST driver fixes
the problem. Other DRM drivers already contain equivalent code.
