Daniel Vetter 0424fdaf88 drm/prime: Actually remove DRIVER_PRIME everywhere
Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous
patches already.

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.

Douglas Anderson 527e4ca3b6 drm/rockchip: Base adjustments of the mode based on prev adjustments
In vop_crtc_mode_fixup() we fixup the mode to show what we actually
will be able to achieve.  However we should base our adjustments on
any previous adjustments that were made.

As an example, the dw_hdmi driver may wish to make some small
adjustments to clock rates in its atomic_check() function.  If it
does, it will update the adjusted_mode.  We shouldn't throw away those
adjustments.

NOTE: the version of the dw_hdmi driver upstream doesn't _actually_
make such adjustments, but downstream in Chrome OS it does.  It is
plausible that one day we'll figure out how to cleanly make that
happen in an upstream-friendly way, so we should prepare by using the
right mode.

Douglas Anderson 99b9683f21 drm/rockchip: Properly adjust to a true clock in adjusted_mode
When fixing up the clock in vop_crtc_mode_fixup() we're not doing it
quite correctly.  Specifically if we've got the true clock 266666667 Hz,
we'll perform this calculation:
   266666667 / 1000 => 266666

Later when we try to set the clock we'll do clk_set_rate(266666 *
1000).  The common clock framework won't actually pick the proper clock
in this case since it always wants clocks <= the specified one.

Let's solve this by using DIV_ROUND_UP.

Sandor Yu de85ec271a drm/rockchip: cdn-dp: correct rate in the struct drm_dp_link assignment
The value stored in the rate field of struct drm_dp_link should
be the actual link-rate and not the bw_code.

Right now the driver stores the code and converts it to the rate.
So fixup the driver to store the rate itself.

Douglas Anderson 27c9130bae drm/rockchip: dw_hdmi: Handle suspend/resume
On Rockchip rk3288-based Chromebooks when you do a suspend/resume
cycle:

1. You lose the ability to detect an HDMI device being plugged in.

2. If you're using the i2c bus built in to dw_hdmi then it stops
working.

Let's call the core dw-hdmi's suspend/resume functions to restore
things.

NOTE: in downstream Chrome OS (based on kernel 3.14) we used the
"late/early" versions of suspend/resume because we found that the VOP
was sometimes resuming before dw_hdmi and then calling into us before
we were fully resumed.  For now I have gone back to the normal
suspend/resume because I can't reproduce the problems.

Helen Koike d985a35332 drm/rockchip: fix fb references in async update
In the case of async update, modifications are done in place, i.e. in the
current plane state, so the new_state is prepared and the new_state is
cleaned up (instead of the old_state, unlike what happens in a
normal sync update).
To cleanup the old_fb properly, it needs to be placed in the new_state
in the end of async_update, so cleanup call will unreference the old_fb
correctly.

Also, the previous code had a:

	plane_state = plane->funcs->atomic_duplicate_state(plane);
	...
	swap(plane_state, plane->state);

	if (plane->state->fb && plane->state->fb != new_state->fb) {
	...
	}

Which was wrong, as the fb were just assigned to be equal, so this if
statement nevers evaluates to true.

Another details is that the function drm_crtc_vblank_get() can only be
called when vop->is_enabled is true, otherwise it has no effect and
trows a WARN_ON().

Calling drm_atomic_set_fb_for_plane() (which get a referent of the new
fb and pus the old fb) is not required, as it is taken care by
drm_mode_cursor_universal() when calling
drm_atomic_helper_update_plane().

drm: Remove users of drm_format_info_plane_cpp
drm_format_info_plane_cpp() basically just returns the cpp array content
found in the drm_format_info structure.

Since it's pretty trivial, let's remove the function and have the users use
the array directly

drm/fourcc: Pass the format_info pointer to drm_format_plane_cpp
So far, the drm_format_plane_cpp function was operating on the format's
fourcc and was doing a lookup to retrieve the drm_format_info structure and
return the cpp.

However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.

Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent. In order to be extra consistent, also rename that
function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

drm: Remove users of drm_format_(horz|vert)_chroma_subsampling
drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.

Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.

Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

The Rockchip VOP driver has a function, scl_vop_cal_scl_fac, that will

However, its only caller already derefences the drm_format_info structure

As explained by Robin Murphy:
> the IOMMU shutdown disables paging, so if the VOP is still
> scanning out then that will result in whatever IOVAs it was using now going
> straight out onto the bus as physical addresses.

We had a more radical approach before in commit
7f3ef5dedb ("drm/rockchip: Allow driver to be shutdown on reboot/kexec")
but that resulted in new warnings and oopses on shutdown on rk3399
chromeos devices.

So second try is resurrecting Vicentes shutdown change which should
achieve the same result but in a less drastic way.

Daniel Vetter 8782c647ae drm/fbdev: Make skip_vt_switch the default
KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.

Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.

But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".

Jonas Karlman e9abc611a9 drm/rockchip: vop: reset scale mode when win is disabled
NV12 framebuffers produced by the VPU shows distorted on RK3288
after win has been disabled when scaling is active.

This issue can be reproduced using a 1080p modeset by:
- Scale a 1280x720 NV12 framebuffer to 1920x1080 on win0
- Disable win0
- Display a 1920x1080 NV12 framebuffer without scaling on win0
- Output will now show the framebuffer distorted

And by:
- Scale a 1280x720 NV12 framebuffer to 1920x1080
- Change to a 720p modeset (win gets disabled and scaling reset to none)
- Output will now show the framebuffer distorted

Fix this by setting scale mode to none when win is disabled.

Heiko Stuebner ce6912b407 drm/rockchip: check yuv2yuv existence before assigning window data
Before assigning window data, we should check if the yuv2yuv vop-data
is set at all, because it looks like it can otherwise reference something
wrong, as I saw on my rk3188 today which ended up in a null pointer
dereference in vop_plane_atomic_update when accessing the yuv2yuv data.

Daniel Vetter 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.

Mark Yao f4a6de855e drm: rockchip: vop: add rk3066 vop definitions
This patch adds the rk3066 VOP definitions.

The VOP or LCD Controller serves as interface between
framebuffer memory and a display device (LCD panel or TV set).

This SOC has two symmetrical LCDC's for a dual panel application.

A LCDC has 5 display layers.
Only 3 are used here.

- Video layer 0 (Win0)
- Video layer 1 (Win1)
- OSD layer     (Win2)

Win0 and Win1 are exchangeable.
Maximum resolution is 1920x1080.

The LCDC0 output is connected to:
- LCDC0 IO (without IOMUX)
- HDMI TX video input

The LCDC1 output is connected to:
- LCDC1 IO (with IOMUX)
- HDMI TX video input

The HDMI TX input can switch between LCDC0 and LCDC1.

Daniele Castagna 677e8bbc0e drm/rockchip: Add reflection properties
Add the KMS plane rotation property to the DRM rockchip driver,
for SoCs RK3328, RK3368 and RK3399.

RK3288 only supports rotation at the display level (i.e. CRTC),
but for now we are only interested in plane rotation.

This commit only adds support for the value of reflect-y
and reflect-x (i.e. mirroring).

Note that y-mirroring is not compatible with YUV.

The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.

X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17

Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33

XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49

This commit splits the registers for RK3288 from those
for RK3328, RK3368 and RK3399. It seems RK3288 does not
support plane x-y-mirroring, and so in order to support this
for the other SoCs, we need to have separate set of registers
for win0 and win1.

Fix a small typo in the macros VOP argument. The macro argument
is currently wrongly named "x", and then never used. The code
built fine almost by accident, as the macros are always used
in a context where a proper "vop" symbol exists.

This fix is almost cosmetic, as the resulting code shouldn't change.

Daniele Castagna 1c21aa8f2b drm/rockchip: Fix YUV buffers color rendering
Currently, YUV hardware overlays are converted to RGB using
a color space conversion different than BT.601.

The result is that colors of e.g. NV12 buffers don't match
colors of YUV hardware overlays.

In order to fix this, enable YUV2YUV and set appropriate coefficients
for formats such as NV12 to be displayed correctly.

This commit was tested using modetest, gstreamer and chromeos (hardware
accelerated video playback). Before the commit, tests rendering
with NV12 format resulted in colors not displayed correctly.

Test examples (Tested on RK3399 and RK3288 boards
connected to HDMI monitor):

  $ modetest 39@32:1920x1080@NV12
  $ gst-launch-1.0 videotestrc ! video/x-raw,format=NV12 ! kmssink
