drm_crtc.h has no need for linux/media-bus-format.h, so don't
include it. Avoids useless rebuilds of the entire universe when
touching linux/media-bus-format.h.
Quite a few placs do currently depend on linux/media-bus-format.h
without actually including it directly. All of those need to be
fixed up.
v2: Deal with ingenic as well
v3: Fix up mxsfb and remaining parts of imx

D1 has a TCON TOP, so its quirks are similar to those for the R40 TCONs.
While there are some register changes, the part of the TCON TV supported
by the driver matches the R40 quirks, so that quirks structure can be
reused. D1 has the first supported TCON LCD with a TCON TOP, so the TCON
LCD needs a new quirks structure.
D1's TCON LCD hardware supports LVDS; in fact it provides dual-link LVDS
from a single TCON. However, it comes with a brand new LVDS PHY. Since
this PHY has not been tested, leave out LVDS driver support for now.

Channel 1 has polarity bits for vsync and hsync signals but driver never
sets them. It turns out that with pre-HDMI2 controllers seemingly there
is no issue if polarity is not set. However, with HDMI2 controllers
(H6) there often comes to de-synchronization due to phase shift. This
causes flickering screen. It's safe to assume that similar issues might
happen also with pre-HDMI2 controllers.
Solve issue with setting vsync and hsync polarity. Note that display
stacks with tcon top have polarity bits actually in tcon0 polarity
register.

During commit 88bc4178568b ("drm: Use new
DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_*
macros have been changed to avoid ambiguity but just because of this
ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning
_SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but
instead of swapping phase values, let's adopt an easier approach Maxime
suggested:
It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to
invert DCLK polarity and this makes things really easier than before. So
let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE
as bit 26 and activating according to bus_flags the same way it is done
for all the other signals polarity.

The LVDS controller can invert the polarity / lanes of the LVDS output.
The default polarity causes some issues on some panels.
However, U-Boot has always used the opposite polarity without any reported
issue, and the only currently supported LVDS panel in-tree (the TBS A711)
seems to be able to work with both settings.
Let's just use the same polarity than U-Boot to be more consistent and
hopefully support all the panels.

In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK
to 1.") it was assumed that all TCON variants support a minimum divider
of 1 if only DCLK was used.
However, the oldest generation of hardware only supports minimum divider
of 4 if only DCLK is used. If a divider of 1 was used on this old
hardware, some scrolling artifact would appear. A divider of 2 seemed
OK, but a divider of 3 had artifacts as well.
Set the minimum divider when outputing to parallel RGB based on the
hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20)
hardware, and a minimum of 1 for the rest. A value is not set for the
TCON variants lacking channel 0.
This fixes the scrolling artifacts seen on my A13 tablet.

The datasheet of V3s (and various other chips) wrote
that TCON0_DCLK_DIV can be >= 1 if only dclk is used,
and must >= 6 if dclk1 or dclk2 is used. As currently
neither dclk1 nor dclk2 is used (no writes to these
bits), let's set minimal division to 1.
If this minimal division is 6, some common dot clock
frequencies can't be produced (e.g. 30MHz will not be
possible and will fallback to 25MHz), which is
obviously not an expected behaviour.

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

put into the places they are needed.

We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.
Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

The current code allows the TCON clock divider to have a range between 4
and 127 when feeding the DSI controller.
The only display supported so far had a display clock rate that ended up
using a divider of 4, but testing with other displays show that only 4
seems to be functional.
This also aligns with what Allwinner is doing in their BSP, so let's just
hardcode that we want a divider of 4 when using the DSI output.

When initializing clocks, a reference to the TCON channel 0 clock is
obtained. However, the clock is never prepared and enabled later.
Switching from simplefb to DRM actually disables the clock (that was
usually configured by U-Boot) because of that.
On the V3s, this results in a hang when writing to some mixer registers
when switching over to DRM from simplefb.
Fix this by preparing and enabling the clock when initializing other
clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is
apparently too late and results in the same mixer register access hang.

The A23's display pipeline is similar to the A33. Differences include:
- Display backend supports larger layers, 8192x8192 instead of 2048x2048
- TCON has DMA input
- There is no SAT module packed in the display backend
Add support for the display pipeline and its components.
As the MIPI DSI output device is not officially documented, and there
are no A23 reference devices to test it, it is not covered by this

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.

rely on the panel registered with the TCON driver. However, bridges are

Even in the case of bridges, the connector is registered with the

The hardware supports dithering on TCON channel 0 which is used for LCD
panels.
Dithering is a method of approximating a color from a mixture of other
colors when the required color isn't available. It reduces color
banding artifacts that can be observed when displaying gradients
(e.g. grayscale gradients). This may occur when the image that needs
to be displayed is 24-bit but the LCD panel is a lower bit depth and
does not perform dithering on its own.

sun4i_tcon0_mode_set_cpu() currently accepts struct mipi_dsi_device *
as its second parameter. This is derived from drm_encoder.
The DSI encoder is tied to the CPU interface mode of the TCON as a
special case. In theory, if hardware were available, we could also
support normal CPU interface modes. It is better to pass the generic
encoder instead of the specialized mipi_dsi_device, and handle the
differences inside the function.
Passing the encoder would also enable the function to pass it, or any
other data structures related to it, to other functions expecting it.
One such example would be dithering support that will be added in a
later patch, which looks at properties tied to the connector to
determine whether dithering should be enabled or not.

Till now, new way of matching engines with TCONs was reading their
respective ids and match them by those ids. However, with introduction
of TCON TOP, that might not be so straightforward anymore.
- there might be more TCONs that engines (mixers)
- TCON ids might have non-consecutive ids
Workaround that by matching mixer id with TCON index from TCON list.
For example, R40 has 2 mixers and 4 TCONs. Board designer can choose
2 outputs, which are connected to any of those 4 TCONs. As long as there
are only 2 TCONs enabled in DT, using index in list as alternative id,
will allow to match them with mixer 0 and 1.

Handle both positive and negative dclk polarity,
according to bus_flags, taking care of this:
On A20 and similar SoCs, the only way to achieve Positive Edge
(Rising Edge), is setting dclk clock phase to 2/3(240°).
By default TCON works in Negative Edge(Falling Edge), this is why phase
is set to 0 in that case.
Unfortunately there's no way to logically invert dclk through IO_POL
register.
The only acceptable way to work, triple checked with scope,
is using clock phase set to 0° for Negative Edge and set to 240° for
Positive Edge.
On A33 and similar SoCs there would be a 90° phase option, but it divides
also dclk by 2.
This patch is a way to avoid quirks all around TCON and DOTCLOCK drivers
for using A33 90° phase divided by 2 and consequently increase code
complexity.
Check if panel is used. TCON can also handle VGA DAC, then panel could
be empty.
