For RK3399, the grf clk should be enabled before writing grf registers,
otherwise the register value can not be changed.

For RK3399, the phy_cfg_clk is a required clock, if phy_cfg_clk is
disabled, MIPI phy can not work. Let's return a error if there is no
phy_cfg_clk in dts property, when the pdata match RK3399.

This was missed in Tomeu's patch. Also remove the kerneldoc for the

drm_dp_mst_allocate_vcpi() apart from setting up the vcpi structure,
also finds if there are enough slots available. This check is a duplicate
of that implemented in drm_dp_mst_find_vcpi_slots(). Let's move this check
out and reuse the existing drm_dp_mst_find_vcpi_slots() function to check
if there are enough vcpi slots before allocating them.
This brings the check to one place. Additionally drivers that will use MST
state tracking for atomic modesets can use the atomic version of
find_vcpi_slots() and reuse drm_dp_mst_allocate_vcpi()

The avail_slots member in the MST topology manager is never updated to

total slots, 63. So, let's make that check obvious and remove
avail_slots. While at it, make debug messages more descriptive.

The total vcpi time slots is always 63 and does not depend on the link BW,
remove total_slots from MST topology manager struct. The next change is to
remove total_pbn which is hardcoded to 2560. The total PBN that the
topology manager allocates from depends on the link rate and is not a
constant. So, fix this by removing the total_pbn member itself.

Allow framebuffers dimesions to be misaligned w.r.t. the subsampling
factors. No real reason the core should have to enforce this, and
it definitely starts to cause us issues with the i915 CCS support.
So let's just lift the restriction.
Let's start to round up when computing the color plane dimesions
so that we'll not end up with too low an estimate for the memory
requirements and whatnot.

This patch does following:
- Adds a new structure (drm_hdmi_info) in drm_display_info.
This structure will be used to save and indicate if sink
supports advanced HDMI 2.0 features
- Adds another structure drm_scdc within drm_hdmi_info, to
reflect scdc support and capabilities in connected HDMI 2.0 sink.
- Checks the HF-VSDB block for presence of SCDC, and marks it
in scdc structure
- If SCDC is present, checks if sink is capable of generating
SCDC read request, and marks it in scdc structure.
V2: Addressed review comments
Thierry:
- Fix typos in commit message and make abbreviation consistent
across the commit message.
- Change structure object name from hdmi_info -> hdmi
- Fix typos and abbreviations in description of structure drm_hdmi_info
end the description with a full stop.
- Create a structure drm_scdc, and keep all information related to SCDC
register set (supported, read request supported) etc in it.
Ville:
- Change rr -> read_request
- Call drm_detect_scrambling function drm_parse_hf_vsdb so that all

patches.

git://git.pengutronix.de/git/pza/linux into drm-next
imx-drm PRE/PRG support, deferred plane disabling, separate alpha support
- Initial support for the Prefetch Resolve Engine/Gasket on i.MX6QP,
improving linear scanout buffer memory bandwidth utilization. This
will in the future grow reordering support and allow direct scanout
of Vivante tiled renderbuffers from the GPU.
- Deferred plane disabling gets rid of some busy waiting in the atomic
plane disable and crtc disable paths that lead to wait_for_vblank
timeouts.
- Add support for RGBA formats with a separate alpha plane, that can
reduce memory bandwidth utilization for mostly transparent overlay
planes by skipping color reads for completely transparent regions.
- Allow moving an active overlay plane without enforcing a modeset.
- Add 8-bit and 16-bit bayer formats to ipu_cpmem_set_image.
- Set the base address in ipu_cpmem_set_image even for invalid formats
to increase robustness against errors.
- Use drm_plane_helper_check_state in plane atomic_check.
- Some cleanup.

The pointer plane is always null on the error path at label 'fail'
hence the check if it is non-null is redundant. We can therefore
remove the check and the destruction of plane as well as the fail
error path and instead just return an -ENOMEM ERR_PTR.

Geminilake also supports pooled EUs. Enable it.
It is unclear if the recommendation to disable it for 2x6 configurations
from commit e015dd69b2cf ("drm/i915/bxt: Add WaEnablePooledEuFor2x6")
should also apply to GLK, but it is applied anyway to be on the safe
side. That restriction can be lifted later if determined not to impact
performance.
The extra restriction should not impact user space either. The only user
space that uses this feature is Beignet, and it only does so for 3x6
devices. See See Beignet's commit 6901899ec90a ("Runtime: set the sub
slice according to kernel pooled EU configure.").
v2: Improve commit message. (Mika, Roy)

From commit a6508ded2a66 ("drm/i915: Use page coloring to provide the guard
page at the end of the GTT"), we no longer explicitly subtract guard page
at end for GGTT address space init, so shouldn't subtract that for vGPU
balloon too, as that will leave that end page to be available for
vGPU. Change balloon to cover full range too.
This fixes to use recent drm-intel tip kernel for guest OS. Found by GVT-g
cmd parser that guest kernel uses end page as scratch then try to run
MI_STORE_REG_MEM onto it.

The HDMI encoder IP embeds all needed blocks to output audio, with a
custom DAI called MAI moving audio between the two parts of the HDMI
core. This driver now exposes a sound card to let users stream audio
to their display.
Using the hdmi-codec driver has been considered here, but MAI meant
having to significantly rework hdmi-codec, and it would have left
little shared code with the I2S mode anyway.
The encoder requires that the audio be SPDIF-formatted frames only,
which alsalib will format-convert for us.
This patch is the combined work of Eric Anholt (initial register setup
with a separate dmaengine driver and using simple-audio-card) and
Boris Brezillon (moving it all into HDMI, massive debug to get it
actually working), and which Eric has the permission to release.
v2: Drop "-audio" from sound card name, since that's already implied
(suggestion by Boris)

When we wedge the device, we override engine->submit_request with a nop
to ensure that all in-flight requests are marked in error. However, igt
would like to unwedge the device to test -EIO handling. This requires us
to flush those in-flight requests and restore the original
engine->submit_request.
v2: Use a vfunc to unify enabling request submission to engines
v3: Split new vfunc to a separate patch.
v4: Make the wait interruptible -- the third party fences we wait upon
may be indefinitely broken, so allow the reset to be aborted.

I915_RESET_IN_PROGRESS is being used for both signaling the requirement
to i915_mutex_lock_interruptible() to avoid taking the struct_mutex and
to instruct a waiter (already holding the struct_mutex) to perform the
reset. To allow for a little more coordination, split these two meaning
into a couple of distinct flags. I915_RESET_BACKOFF tells
i915_mutex_lock_interruptible() not to acquire the mutex and
I915_RESET_HANDOFF tells the waiter to call i915_reset().
