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.

b6e075c3cb drm/atmel-hlcdc: support bus-width (12/16/18/24) in endpoint nodes
This beats the heuristic that the connector is involved in what format
should be output for cases where this fails.

E.g. if there is a bridge that changes format between the encoder and the
connector, or if some of the RGB pins between the lcd controller and the
encoder are not routed on the PCB.

This is critical for the devices that have the "conflicting output
formats" issue (SAM9N12, SAM9X5, SAMA5D3), since the most significant
RGB bits move around depending on the selected output mode. For
devices that do not have the "conflicting output formats" issue
(SAMA5D2, SAMA5D4), this is completely irrelevant.

9946a3a9db drm/atmel-hlcdc: allow selecting a higher pixel-clock than requested
But only if the highest pixel-clock frequency lower than requested
is significantly less accurate than the lowest frequency higher than
requested.

I pulled "10 times" as the discriminator out of the hat, and went with
that.

This is useful, if e.g. the target pixel-clock is 65MHz and the sys_clk
is 132MHz. In this case the highest possible pixel-clock lower than the
requested 65MHz is 52.8MHz, which is almost 20% off (and outside the
spec for the panel). The lowest possible pixel-clock higher than 65MHz
is 66MHz, which is a *much* better match, and only 1.5% off.

319711f982 drm/atmel-hlcdc: prefer a higher rate clock as pixel-clock base
If the divider used to get the pixel-clock is small, the granularity
of the frequencies possible for the pixel-clock is quite coarse. E.g.
requesting a pixel-clock of 65MHz with a sys_clk of 132MHz results
in the divider being set to 3 ending up with 44MHz.

By preferring the doubled sys_clk as base, the divider instead ends
up as 5 yielding a pixel-clock of 52.8Mhz, which is a definite
improvement.

While at it, clamp the divider so that it does not overflow in case
it gets big.

9a45d33cdf drm/atmel-hlcdc: Simplify the HLCDC layer logic
An HLCDC layers in Atmel's nomenclature is either a DRM plane or a 'Post
Processing Layer' which can be used to output the results of the HLCDC
composition in a memory buffer.

atmel_hlcdc_layer.c was designed to be generic enough to be re-usable in
both cases, but we're not exposing the post-processing layer yet, and
even if we were, I'm not sure the code would provide the necessary tools
to manipulate this kind of layer.

Moreover, the code in atmel_hlcdc_{plane,layer}.c was designed before the
atomic modesetting API, and was trying solve the
check-setting/commit-if-ok/rollback-otherwise problem, which is now
entirely solved by the existing core infrastructure.

And finally, the code in atmel_hlcdc_layer.c is over-complicated compared
to what we really need. This rework is a good excuse to simplify it. Note
that this rework solves an existing resource leak (leading to a -EBUSY
error) which I failed to clearly identify.

aca63b7661 drm: atmel-hlcdc: move output mode selection in CRTC implementation
In order to support multiple outputs we need to move the output mode
selection to the CRTC object, so that the output validity check can be
done against the drm_atomic_state.

If the connectors selected by a specific mode setting are requiring
incompatible bus format the atomic operation is aborted (->atomic_check()
returns -EINVAL).

In order to implement that, we need to define our own CRTC state and
overload default ->reset(), ->atomic_duplicate_state() and
->atomic_destroy_state() functions.

f98828769c drm: Pass 'name' to drm_crtc_init_with_planes()
Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

613d2b2721 drm/atomic: pass old crtc state to atomic_begin/flush.
In intel it's useful to keep track of some state changes with old
crtc state vs new state, for example to disable initial planes or
when a modeset's prevented during fastboot.

f026eb6e03 drm: atmel-hlcdc: use appropriate enabled flag in suspend/resume
Unfortunately we used the enabled flag in struct drm_crtc instead of the
enabled flag in struct atmel_hlcdc_crtc. This obviously leads to
discrepancies on crtc enable state.

This patch fixes the issue by using the struct atmel_hlcdc_crtc enabled
flag in PM support.

5957017db0 drm: atmel-hlcdc: add discard area support
The HLCDC IP provides a way to discard a specific area on the primary
plane (in case at least one of the overlay is activated and alpha
blending is disabled).
Doing this will reduce the amount of data to transfer from the main
memory to the Display Controller, and thus alleviate the load on the
memory bus (since this link is quite limited on such hardware,
this kind of optimization is really important).

1a396789f6 drm: add Atmel HLCDC Display Controller support
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.

This display controller supports at least one primary plane and might
provide several overlays and an hardware cursor depending on the IP
version.

At the moment, this driver only implements an RGB connector to interface
with LCD panels, but support for other kind of external devices might be
added later.
