Similar to the previous commit, convert drivers open coding OF graph
parsing to use drm_of_find_panel_or_bridge instead.
This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular
board, so we want to avoid spurious messages. Plus the kernel is not a
DT validator.

Allow the planes to use the PRG/PRE units as linear prefetchers when
possible. This improves DRAM efficiency a bit and reduces the chance
for display underflow when the memory subsystem is under load.
This does not yet support scanning out tiled buffers directly, as this
needs more work, but it already wires up the basic interaction between
imx-drm, the IPUv3 driver and the PRG and PRE drivers.

The IPUv3 can read 8-bit alpha values from a separate plane buffer using
a companion IDMAC channel driven by the Alpha Transparency Controller
(ATC) for the graphics channels. The conditional read mechanism allows
to reduce memory bandwidth by skipping reads of color data for
completely transparent bursts.

The DP (display processor) channel disable code tried to busy wait for
the DP sync flow end interrupt status bit when disabling the partial
plane without a full modeset. That never worked reliably, and it was
disabled completely by the recent "gpu: ipu-v3: remove IRQ dance on DC
channel disable" patch, causing ipu_wait_interrupt to always time out
after 50 ms, which in turn would trigger a timeout in
drm_atomic_helper_wait_for_vblanks.
This patch changes ipu_plane_atomic_disable to only queue a DP channel
register update at the next frame boundary and set a flag, which can be
done without any waiting whatsoever. The imx_drm_atomic_commit_tail then
calls a new ipu_plane_disable_deferred function that does the actual
IDMAC teardown of the planes that are flagged for deferred disabling,
after waiting for the vblank.

Less code ftw.
This converts all drivers except the tinydrm helper module. That one
needs more work, since it gets the THIS_MODULE reference from
tinydrm.ko instead of the actual driver module like it should.
Probably needs a similar trick like I used here with generating the

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Rather than compare the format u32s of two format infos, we can direclty
compare the format info pointers themselves. Noramlly all the ->format
pointers all point to somwehere in the big array, so this is a valid
way to test for equality.
Also drivers may want to point ->format at a private format info struct
instead (eg. for special compressed formats with extra planes), so
just comparing the pixel format values wouldn't necessaritly even work.
But comparing the pointers will also take care of that case.

If the DC clock is disabled before the attached IDMACs are properly
stopped the IDMACs may hang the IPU or even the whole system.
Make sure the IDMACs are in safe state by disabling the planes before
removal of the DC clock.
Also set the atomic parameter to false to stop calling the atomic_begin
hook, which does nothing useful as we immediately afterwards turn off
vblank interrupts and possibly send the pending vblank event.

drm_atomic_set_fence_for_plane() is smart and won't overwrite
plane_state->fence if the user already set an explicit fence there.

To support 4:2:2 or 4:4:4 chroma subsampling, divide the x/y offsets in

ipu_plane_atomic_set_base is called from ipu_plane_atomic_update in two
different places, depending on whether drm_atomic_crtc_needs_modeset is
true. Also depending on the same condition, this function does two
different things.
This patch removes the indirection by merging the relevant parts into
ipu_plane_atomic_update, making the actual code flow more obvious as a
result. Also remove the duplicate planar format comment, which is
already found in ipu_plane_atomic_check.

If the framebuffer pixel format is planar YUV and unchanged, but the U
or V plane offsets change, do not return an error, but request a modeset
instead.

Without this patch, after enabling the overlay plane with an RGBA
framebuffer, switching to a framebuffer without alpha channel would
cause the plane to vanish, since the pixel local alpha is constant
zero in that case. Disable local alpha again when setting an opaque
framebuffer.

Before accessing the u/v offset(aka, u/vbo for IPUv3) of the old plane state's
relevant fb, we should make sure the fb is in YU12 or YV12 pixel format(which
are the two YUV pixel formats we support only), otherwise, we are likely to
trigger BUG_ON() in drm_plane_state_to_u/vbo() since the fb's pixel format is
probably not YU12 or YV12.

We added active plane reconfiguration support by forcing a full modeset
operation. So, looking at old_plane_state->fb to determine whether we need
to set u/v offset(aka, u/vbo for IPUv3) in ipu_plane_atomic_set_base()
or not is no more correct. Instead, we should do that only when we don't
need modeset.

We added active plane reconfiguration support by forcing a full modeset

switch EBA buffer(for hardware double buffering) in ipu_plane_atomic_set_base()
or not is no more correct. Instead, we should do that only when we don't need
modeset, otherwise, we initialize the two EBA buffers with the buffer address.

The imx_drm_bind function causes a warning in linux-next when
CONFIG_DRM_FBDEV_EMULATION is not set:

drivers/gpu/drm/imx/imx-drm-core.c:441:1: error: label 'err_unbind' defined but not used [-Werror=unused-label]
I don't understand why the warning only showed up now, as the
code has not been modified recently, but there is an obvious
fix in adding another #if for the symbol.
