drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference
[ Upstream commit 935a92a1c400285545198ca2800a4c6c519c650a ]

[ Upstream commit 935a92a1c400285545198ca2800a4c6c519c650a ]
In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is assigned to mhdp_state->current_mode, and there is a dereference of it in drm_mode_set_name(), which will lead to a NULL pointer dereference on failure of drm_mode_duplicate().
Fix this bug add a check of mhdp_state->current_mode.

When CONFIG_IO is disabled, above two variables are not used, since the place where it is used is inclueded in the macro CONFIG_OF.
Even for drivers that do not depend on CONFIG_OF, it's almost always better to leave out the of_match_ptr(), since the only thing it can possibly do is to save a few bytes of .text if a driver can be used both with and without it. Hence we remove all of_match_ptr() used in other places.

drm: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

drm/bridge: cdns-mhdp8546: Fix the interrupt enable/disable
When removing the tidss driver, there is a warning reported by kernel about an unhandled interrupt for mhdp driver.
[ 43.238895] irq 31: nobody cared (try booting with the "irqpoll" option) ... [snipped backtrace] [ 43.330735] handlers: [ 43.333020] [<000000005367c4f9>] irq_default_primary_handler threaded [<000000007e02b601>] cdns_mhdp_irq_handler [cdns_mhdp8546] [ 43.344607] Disabling IRQ #31
This happens because as part of cdns_mhdp_bridge_hpd_disable, driver tries to disable the interrupts. While disabling the SW_EVENT interrupts, it accidentally enables the MBOX interrupts, which are not handled by the driver.
Fix this with a read-modify-write to update only required bits. Use the enable / disable function as required in other places.

gpu/drm/bridge/cadence: avoid flush_scheduled_work() usage
Like commit c4f135d643823a86 ("workqueue: Wrap flush_workqueue() using a macro") says, flush_scheduled_work() is dangerous and will be forbidden. We are on the way for removing all flush_scheduled_work() callers from the kernel, and this patch is for removing flush_scheduled_work() call from cadence driver.
Since cdns-mhdp8546 driver uses 4 works
mhdp->modeset_retry_work mhdp->hpd_work mhdp->hdcp.check_work mhdp->hdcp.prop_work
I assume that flush_scheduled_work() in cdns_mhdp_remove() needs to wait for only these 4 works.
Since mhdp->modeset_retry_work already uses cancel_work_sync(), I assume that flush_scheduled_work() needs to wait for only 3 works. But I came to wonder whether mhdp->hdcp.check_work should be flushed or cancelled.
While flush_scheduled_work() waits for completion of works which were already queued to system_wq, mhdp->hdcp.check_work is a delayed work. That is, this work won't be queued to system_wq unless timeout expires.
Current code will wait for mhdp->hdcp.check_work only if timeout already expired. If timeout is not expired yet, flush_scheduled_work() will fail to cancel mhdp->hdcp.check_work, and cdns_mhdp_hdcp_check_work() which is triggered by mhdp->hdcp.check_work will schedule hdcp->check_work, which is too late for flush_scheduled_work() to wait for completion of cdns_mhdp_hdcp_prop_work().
But since I couldn't get comments on how do we want to handle this race window [1], this patch chose "do nothing" for mhdp->hdcp.check_work and mhdp->hdcp.prop_work. That is, I assume that flush_scheduled_work() in cdns_mhdp_remove() needs to wait for only mhdp->hpd_work work.

Quite a few placs do currently depend on linux/media-bus-format.h without actually including it directly. All of those need to be fixed up.

Rename dp/ to display/ to account for additional display-related helpers, such as HDMI. Update all related include statements. No functional changes.
Various drivers, such as i915 and amdgpu, use similar naming scheme by putting code for video-output standards into a local display/ directory. The new directory's name is aligned with this convention.

drm/dp: Add backpointer to drm_device in drm_dp_aux
This is something that we've wanted for a while now: the ability to actually look up the respective drm_device for a given drm_dp_aux struct. This will also allow us to transition over to using the drm_dbg_*() helpers for debug message printing, as we'll finally have a drm_device to reference for doing so.
Note that there is one limitation with this - because some DP AUX adapters exist as platform devices which are initialized independently of their respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be non-NULL until drm_dp_aux_register() has been called. We make sure to point this out in the documentation for struct drm_dp_aux.
v3: * Add WARN_ON_ONCE() to drm_dp_aux_register() if drm_dev isn't filled out
