0c1f528cb1 drm: handle HDMI 2.0 VICs in AVI info-frames
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).

This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.

This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.

In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

0b20a0f8c3 drm: Add old state pointer to CRTC .enable() helper function
The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.

While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

5ac5895a84 drm/mediatek: separate color module to fixup error memory reallocation
Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different
hardware settings) calls devm_kfree() and then devm_kzalloc() to
reallocate color module data structure.  But this reallocation cannnot
guarantee the new address is unchanged, but the caller will use the
old address, which is wrong.

Fix it by separate color module from general components, this patch
separate color module to independent files, like mtk_disp_ovl.c and
mtk_disp_rdma.c do

instead of parsing the endpoint node and then getting the remote device
node. Now drivers can just specify the device node and which

of the graph binding are nicely abstracted into the core OF graph code.

3bb80f2495 drm: bridge: Link encoder and bridge in core code
Instead of linking encoders and bridges in every driver (and getting it
wrong half of the time, as many drivers forget to set the drm_bridge
encoder pointer), do so in core code. The drm_bridge_attach() function
needs the encoder and optional previous bridge to perform that task,
update all the callers.

Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e.
Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP
mode, those signals will cause h-time larger than normal and reduce FPS.
So need to multiply a coefficient to offset the extra signal's effect.
  coefficient = ((htotal*bpp/lane_number)+Tlpx+Ths_prep+Ths_zero+
		 Ths_trail+Ths_exit)/(htotal*bpp/lane_number)

0853695c3b drm: Add reference counting to drm_atomic_state
drm_atomic_state has a complicated single owner model that tracks the
single reference from allocation through to destruction on another
thread - or perhaps on a local error path. We can simplify this tracking
by using reference counting (at a cost of a few more atomics). This is
even more beneficial when the lifetime of the state becomes more
convoluted than being passed to a single worker thread for the commit.

2b58e98d42 drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.

7216436420 drm/mediatek: set mt8173 dithering function
Some panels only accept bpc (bit per color) 6-bit.
But, the default bpc in mt8173 display data path is 8-bit.
If we didn't enable dithering function to convert bpc,
display cannot show the smooth grayscale image.

In mt8173, the dithering function in OD (OverDrive) and
GAMMA module, we have to config them with
connector->display_mode.bpc when CRTC initial.

1. Clear the default value at *_DITHER_5 and *_DITHER_7 register.
2. Calculate the LSB_ERR_SHIFT bits and ADD_LSHIFT bits two values.
i.e. Input bpc of OD is 10 bits, we assume the bpc of panel is 6-bit,
so, we need to set 4-bit to LSB_ERR_SHIFT and ADD_LSHIFT bits respectively.
3. Then, set the OD or GAMMA to dithering mode depends on path-1 or path-2.

ac08500c1b drm/mediatek: Fix mtk_atomic_complete for runtime_pm
To properly implement atomic w/ runtime pm, we move
drm_atomic_helper_commit_modeset_enables() above
drm_atomic_helper_commit_planes() to ensure CRTCs are enabled before
modifying plane registers, and set active_only to true to filter out
plane update notifications when the CRTC is disabled.

According to the document from linux kernel:
Set the active_only parameters to true in order not to receive plane
update notifications related to a disabled CRTC. This avoids the need
to manually ignore plane updates in driver code when the driver and/or
hardware can't or just don't need to deal with updates on disabled
CRTCs, for example when supporting runtime PM.

0e4faf679e drm/mediatek: Use drm_plane_helper_check_state()
Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.

This also eliminates the double clipping the driver was doing
in both check and commit phases). And it should fix src coordinate
addr adjustement. Previously the driver was expecting negative dst
coordinates after clipping, which is not going happen, so any clipping
induced addr adjustment simply didn't happen. Neither did the driver
respect any user configured src coordinates, so panning and such would
have been totally broken. It should be all good now.

00085f1efa dma-mapping: use unsigned long for dma_attrs
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer.  Thus the pointer can point to const data.
However the attributes do not have to be a bitfield.  Instead unsigned
long will do fine:

1. This is just simpler.  Both in terms of reading the code and setting
   attributes.  Instead of initializing local attributes on the stack
   and passing pointer to it to dma_set_attr(), just set the bits.

2. It brings safeness and checking for const correctness because the
   attributes are passed by value.

Semantic patches for this change (at least most of them):

a742946a1b drm: Don't call drm_dev_set_unique from platform drivers
Since

commit e112e593b2
Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
Date:   Fri Dec 11 11:20:28 2015 +0100

    drm: use dev_name as default unique name in drm_dev_alloc()

we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name

v2: Rebase on top of mediatek.

e06a44c127 drm/mediatek: Remove IOMMU_DMA select
We get a harmless build warning when trying to use the mediatek DRM
driver with IOMMU support disabled:

	warning: (DRM_MEDIATEK) selects IOMMU_DMA which has unmet direct dependencies (IOMMU_SUPPORT)

However, the IOMMU_DMA symbol is not meant to be used by drivers at all,
and this driver doesn't seem to have a strict dependency on it other
than using the mediatek IOMMU driver that does.

Since we also want to be able to do compile tests with the driver on
other platforms, the IOMMU_DMA symbol should not be selected here.

6c62c98fa4 drm/mediatek: Remove redundant calls to drm_connector_register_all()
Up to now, the recommendation was for drivers to call drm_dev_register()
followed by drm_connector_register_all(). Now that
drm_connector_register() is safe against multiple invocations, we can
move drm_connector_register_all() to drm_dev_register() and not suffer
from any backwards compatibility issues with drivers not following the
more rigorous init ordering.

9b8b013dde drm: Deal with rotation in drm_plane_helper_check_update()
drm_plane_helper_check_update() needs to account for the plane rotation
for correct clipping/scaling calculations. Do so.

There was an earlier attempt [1] to add this into
intel_check_primary_plane() but I requested that it'd be put into the
helper instead. An updated patch never materialized AFAICS, so I went
ahead and cooked one up myself.

v2: Deal with new drm_plane_helper_check_update() callers

56ba355d6b drm/mediatek: enable hdmi output control bit
MT8173 HDMI hardware has a output control bit to enable/disable HDMI
output. Because of security reason, so this bit can ONLY be controlled
in ARM supervisor mode. Now the only way to enter ARM supervisor is the
ARM trusted firmware. So atf provides a API for HDMI driver to call to
setup this HDMI control bit to enable HDMI output in supervisor mode.

This patch adds drivers for the HDMI bridge connected to the DPI0
display subsystem function block, for the HDMI DDC block, and for
the HDMI PHY to support HDMI output.
This includes an interface to the generic hdmi-codec driver to start
or stop audio playback and to retrieve ELD (EDID like data) to limit the
supported audio formats to the HDMI sink capabilities.
