In MDP5 Layer Mixer HW, the blender output is only the blended color
components (i.e R, G and B, or COLOR0/1/2 in MDP5 HW terminology). This
is fed to the BG input of the next blender. We also need to provide an
alpha (COLOR3) value for the BG input at the next stage.
This is configured via using the REG_MDP5_LM_BLEND_COLOR_OUT register.
For each stage, we can propagate either the BG or FG alpha to the next
stage.
The approach taken by the driver is to propagate FG alpha, if the plane
staged on that blender has an alpha. If it doesn't, we try to propagate
the base layer's alpha.
This is borrowed from downstream MDP5 kernel driver. Without this, we
don't see any cursor plane content.

The MDP5 plane's atomic_check ops doesn't perform clipping tests.
This didn't hurt us much in the past, but clipping becomes important
with cursor planes.
Use drm_plane_helper_check_state, the way rockchip/intel/mtk drivers
already do. Use these drivers as reference.
Clipping requires knowledge of the crtc width and height. This requires
us to call drm_atomic_helper_check_modeset before
drm_atomic_helper_check_planes in the driver's atomic_check op, because
check_modetest will populate the mode for the crtc, needed to populate
the clip rectangle.
We update the plane_enabled(state) local helper to use state->visible,
since state->visible and 'state->fb && state->crtc' represent the same
thing.
One issue with the existing code is that we don't have a way to disable
the plane when it's completely clipped out. Until there isn't an update
on the crtc (which would de-stage the plane), we would still see the
plane in its last 'visible' configuration.

Use SSPP_NONE in mdp5_plane_pipe() if there is now hwpipe allocated for
the drm_plane. Returning '0' means we are returning VIG0 pipe.
Also, use the mdp5_pipe enum to pass around the stage array. Initialize
the stage to SSPP_NONE by default.
We do the above because 1) Cursor plane has to be staged at the topmost
blender of the LM, which can result in empty stages in between 2) In
the future, when we support multiple LMs per CRTC. We could have stages
which don't have any pipe assigned to them.

We currently create CRTCs equaling to the # of Layer Mixer blocks we
have on the MDP5 HW. This number is generally more than the # of encoders
(INTFs) we have in the MDSS HW. The number of encoders connected to
displays on the platform (as described by DT) would be even lesser.
Create only N drm_crtcs, where N is the number of drm_encoders
successfully registered. To do this, we call modeset_init_intf() before
we init the drm_crtcs and drm_planes.
Because of this change, setting encoder->possible_crtcs needs to be moved
from construct_encoder() to a later point when we know how many CRTCs we
have.

For the DSI interfaces, the mdp5_kms core creates 2 encoders for video
and command modes.
Create only a single encoder per interface. When creating the encoder, set
the interface type to MDP5_INTF_MODE_NONE. It's the bridge (DSI/HDMI/eDP)
driver's responsibility to set a different interface type. It can use the
the kms func op set_encoder_mode to change the mode of operation, which
in turn would configure the interface type for the INTF.
In mdp5_cmd_encoder.c, we remove the redundant code, and make the commmand
mode funcs as helpers that are used in mdp5_encoder.c

The mdp5 kms driver currently sets up multiple encoders per interface
(INTF), one for each kind of mode of operation it supports.
We create 2 drm_encoders for DSI, one for Video Mode and the other
for Command Mode operation. The reason behind this approach could have
been that we aren't aware of the DSI device's mode of operation when
we create the encoders.
This makes things a bit complicated, since these encoders have to
be further attached to the same DSI bridge. The easier way out is
to create a single encoder, and make the DSI driver set its mode
of operation when we know what the DSI device's mode flags are.
Start with providing a way to set the mdp5_intf_mode using a kms
func that sets the encoder's mode of operation. When constructing
a DSI encoder, we set the mode of operation to Video Mode as
default. When the DSI device is attached to the host, we probe the
DSI mode flags and set the corresponding mode of operation.

We currently create 2 encoders for DSI interfaces, one for command
mode and other for video mode operation. This isn't needed as we
can't really use both the encoders at the same time. It also makes
connecting bridges harder.
Switch to creating a single encoder. For now, we assume that the
encoder is configured only in video mode. Later, the same encoder
would be usable in both modes.

The commit "drm: bridge: Link encoder and bridge in core code" updated
the drm_bridge_attach() API to also include the drm_encoder pointer
the bridge attaches to.
The func msm_dsi_manager_bridge_init() now relies on the drm_encoder
pointer stored in msm_dsi->encoders to pass the encoder to the bridge
API.
msm_dsi->encoders is unfortunately set after this function is called,
resulting in us passing a NULL pointer to drm_brigde_attach. This
results in an error and the DSI driver probe fails.
Move the initialization of msm_dsi->encoders[] a bit up. Also, don't
try to set the encoder's bridge. That's now managed by the bridge
API.

To be consistent with the recent change to enable hotplug detection
early on GEN9 platforms do the same on all non-GMCH platforms starting
from GEN5. On GMCH platforms enabling detection without interrupts isn't
trivial, since AUX and HPD have a shared interrupt line. It could be
done there too by using a SW interrupt mask, but I punt on that for now.

drm/i915/lspcon: Add workaround for resuming in PCON mode
The workaround was added without considering that HPD is low during
the failed AUX transfers the WA fixed. Since the previous patch we
wait for HPD to get asserted. My tests also show that this happens
_after_ the DPCD reads start to return correct values. This
suggests that we don't need this WA any more, let's try to remove

For LSPCON resume time initialization we need to sample the

HPD interrupts which is too late, so bring the enabling of detection
earlier.
This is needed by the next patch.

The drm_mm range manager (within i915_address_space) uses a special
drm_mm_node that excludes the unavailable range (beyond the end of the
drm_mm). However, we play games with the global GTT to use the head_node
to exclude the tail page but tell ourselves that the whole range is
available. This causes an issue when we try to evict using the full
range of the global GTT which is wider than the drm_mm, resulting in
complete confusion and catastrophe. One way to resolve this would be to
use a reserved node to exclude the guard page, or we can treat the
drm_mm's head_node as our guard page and assign it the appropriate
colour.

Allows using atomic flip helpers for drivers
using ASYNC flip.
Remove ASYNC_FLIP restriction in helpers and
caches the page flip flags in drm_crtc_state
to be used in the low level drivers.
v2:
Resending the patch since the original was broken.
v3:
Save flag in crtc_state instead of plane_state
v4:
Reset the flag before using again.
v5:
Fix type in header.
Rename the field to pageflip_flags.
Remove unrelated hunk.

We now have partial VMA support to break large objects into fence sized
regions and no longer have to restrict tiling to small objects on gen2/3

The current tail breaks the pattern of if (check) return false, which
can catch the reader out. If we move the gen2/3 power-of-two test into
the earlier gen2/3 branch, we can eliminate the contrary tail.

The audio chicken bit (register offset 0x62f38) seems required to make
DP audio working on some machines. At least, on Dell Wyse 3040, I
failed to get the audio unless this bit is set once.
Strangely, the bit seems necessary only once, and it persists after
that, even some power-off cycles. The register is supposedly
write-only, so it's no evidence whether the bit keeps effect
persistently. But, judging from the experiment, it looks enough to
set it up once at the device initialization.
The patch is basically a cut from the original patch by Pierre-Louis
Bossart.
v1->v2: drop read since it's a write-only reg.

In commit 957870f93412 ("drm/i915: Split out i915_gem_object_set_tiling()"),
I swapped an alignment check for IS_ALIGNED and in the process removed
the less-than check. That check turns out to be important as it was the
only rejection for stride == 0. Tvrtko did spot it, but I was
overconfident in the IS_ALIGNED() conversion.
