Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

"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

In commit fe64ba5c63 ("drm/rockchip: Resume DP early") we moved
resume to be early but left suspend at its normal time. This seems
like it could be OK, but casues problems if a suspend gets interrupted
partway through. The OS only balances matching suspend/resume levels.
...so if suspend was called then resume will be called. If suspend
late was called then resume early will be called. ...but if suspend
was called resume early might not get called. This leads to an
unbalance in the clock enables / disables.
Lets take the simple fix and just move suspend to be late to match.
This makes the PM core take proper care in keeping things balanced.

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.

Currently both rockchip_drm_psr_activate() and _deactivate() only set the
boolean "active" flag without actually making sure that hardware state
complies with it.
Since we are going to extend the usage of this API to properly lock PSR
for the duration of atomic commits, we change the semantics in following
way:
- a counter is used to track the number of inhibit requests,
- PSR is actually disabled in hardware on first inhibit request,
- PSR enable work is scheduled on last allow request.
The above allows using the API as a way to deterministically synchronize
PSR state changes with other DRM events, i.e. atomic commits and cursor
updates. As a nice side effect, the naming is sorted out and we have
"inhibit" for stopping the software logic and "enable" for hardware
state.

Specifically we can't start doing PSR work until _after_ the whole

The driver that instantiates the bridge should own the drvdata, as all
driver model callbacks (probe, remove, shutdown, PM ops, etc.) are also
owned by its driver struct. Moreover, storing two different pointer
types in driver data depending on driver initialization status is barely
a good practice and in fact has led to many bugs in this driver.
Let's clean up this mess and change Analogix entry points to simply
accept some opaque struct pointer, adjusting their users at the same
time to avoid breaking the compilation.

Force vop output mode on encoder driver seem not a good idea,
EDP, HDMI, DisplayPort all have 10bit input on rk3399,
On non-10bit vop, vop 8bit output bit[0-7] connect to the
encoder high 8bit [2-9].
So force RGB10 to RGB888 on vop driver would be better.
And another problem, EDP check crtc id on atomic_check,
but encoder maybe NULL, so out_mode configure would fail,
it cause edp no display.

We need to set vop config done after update line flag config, it's a

Similar to the previous commit, convert drivers open coding OF graph
parsing to use drm_of_find_panel_or_bridge instead.
This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular
board, so we want to avoid spurious messages. Plus the kernel is not a
DT validator.

There's no point in enabling PSR when the panel doesn't support it.
This also avoids a problem when PSR gets enabled when a CRTC is being
disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR
interrupt on which we wait will never arrive. This was observed on
RK3288 with a panel without PSR (veyron-jaq Chromebook).
It's very easy to reproduce by running the kms_rmfb test in IGT a few
times.

before eventually succeeding:

Remove the delayed worker, opting instead for the non-delayed
variety. Also introduce a lock to ensure we don't have races
with the worker and psr_state. Finally, cancel and wait for
the worker to finish when disabling the bridge.

The DP needs to have resumed once the DRM driver calls
drm_atomic_helper_resume, otherwise the DP clock is still disabled when
the DRM core enables the DP bridge.
Would be nice to use device_pm_wait_for_dev to synchronize these
devices, but the DRM device doesn't know what specific implementation
this bridge has.
