66620f48cb drm/meson: drop use of drmP.h
Drop use of the deprecated drmP.h header.
While doing so used the opportunity
to clean up a little so includes are now
sorted and removed unused include files.
In a few cases added some forwards to allow header
files to built in different include order.

3b7c1237a7 drm/meson: Add G12A support for the DW-HDMI Glue
The Amlogic G12A embeds the same Synopsys DW-HDMI Controller,
but with :
- a "backport" of the HDR signaling registers from more recent
  DW-HDMI controllers, this will need a tweak since it's not
  normally present on this version of the DW-HDMI controller
- A direct mapping of TOP and DW-HDMI registers instead of an
  internal bus accessed using read/write registers
- Support for RX-SENSE, but not yet implemented
- Support for HDMI 2.1 Dynamic HDR, but not yet implemented
- Different registers mapping for the HDMI PHY setup

This patchs adds support for these changes while providing exact
same support as the previous GXBB, GXL & GXM SoCs.

3d565a21f2 drm/meson: fix TMDS clock filtering for DMT monitors
DMT monitors does not necessarely report a maximum TMDS clock
in a VSDB EDID extension.

In this case, all modes are wrongly rejected, including
the DRM fallback EDID.

This patch only rejects modes whith clock > max_tmds_clock if
the max_tmds_clock is specified. This will only reject
4:2:0 HDMI2.0 modes, who reports a clock > max_tmds_clock.

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.

ff217bc710 drm/meson: Add support for VIC alternate timings
This change is an attempt to handle the alternate clock for the CEA mode.
60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC
DRM Driver pixel clock generation.

The actual clock generation will be moved to the Common Clock framework once
all the video clock are handled by the Amlogic Meson SoC clock driver,
then these alternate timings will be handled in the same time in a cleaner
fashion.

So, fix this by enabling the fast_io option in our regmap config so that
regmap uses spinlocks for locking instead of mutexes.

3273fc63e1 drm/meson: Make DMT timings parameters and pixel clock generic
Remove the modes timings tables for DMT modes and calculate the HW
paremeters from the modes timings.

Switch the DMT modes pixel clock calculation out of the static frequency
list to a generic calculation from a range of possible PLL dividers.

This patch is an intermediate step towards usage of the Common Clock
Framwework for PLL setup, by reworking the code to have common
sel_pll() function called by the CEA (HDMI) freq setup and the generic
DMT frequencies setup, we should be able to simply call clk_set_rate()
on the PLL clock handle in a near future.

The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will
never be able to determine by itself, so there is still some work to do for
a full handoff to CCF handling the clocks.

This setup permits setting non-CEA modes like :
- 1600x900-60Hz
- 1280x1024-75Hz
- 1280x1024-60Hz
- 1440x900-60Hz
- 1366x768-60Hz
- 1280x800-60Hz
- 1152x864-75Hz
- 1024x768-75Hz
- 1024x768-70Hz
- 1024x768-60Hz
- 832x624-75Hz
- 800x600-75Hz
- 800x600-72Hz
- 800x600-60Hz
- 640x480-75Hz
- 640x480-73Hz
- 640x480-67Hz

9c936b12f1 drm/meson: Add support for DMT modes on HDMI
This patch adds support for DMT display modes over HDMI.
The modes timings configurations are from the Amlogic Vendor linux tree
and tested over multiples monitors.
Previously only a selected number of CEA modes were supported.

Only these following modes are supported with these changes:
- 640x480@60Hz
- 800x600@60Hz
- 1024x768@60Hz
- 1152x864@75Hz
- 1280x1024@60Hz
- 1600x1200@60Hz
- 1920x1080@60Hz

The associated code to handle the clock rates is also added.

drm/bridge/synopsys: dw-hdmi: don't clobber drvdata
dw_hdmi shouldn't set drvdata since some drivers might need to store
it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi
instead to store it in drvdata. This way drivers are responsible to
store and pass structure when needed.

Idea was taken from the following commit:
8242ecbd59 ("drm/bridge/synopsys: stop clobbering drvdata")

drm/bridge/synopsys: dw-hdmi: Export some PHY related functions
Parts of PHY code could be useful also for custom PHYs. For example,
Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY
with few additional memory mapped registers, so most of the Synopsys PHY
related code could be reused.

Functions exported here are actually not specific to Synopsys PHYs but
to DWC HDMI controller PHY interface. This means that even if the PHY is
completely custom, i.e. not designed by Synopsys, exported functions can
be useful.

b0febde779 drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callback
Now that we have a callback to check if bridge supports a given mode
we can use it in Synopsys Designware HDMI bridge so that we restrict
the number of probbed modes to the ones we can actually display.

Also, there is no need to use mode_fixup() callback as mode_valid()
will handle the mode validation.

NOTE: I also had to change the pdata declaration of mode_valid
custom callback so that the passed modes are const. I also changed
in the platforms I found. Not even compiled it though.
