Having removed one re-lock cycle on the entity->lock in a patch titled
"drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit
larger refactoring we can do the same optimisation on the rq->lock.
(Currently both drm_sched_rq_add_entity() and
drm_sched_rq_update_fifo_locked() take and release the same lock.)
To achieve this we make drm_sched_rq_update_fifo_locked() and
drm_sched_rq_add_entity() expect the rq->lock to be held.
We also align drm_sched_rq_update_fifo_locked(),
drm_sched_rq_add_entity() and
drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a
parameter to the latter.
v2:
* Fix after rebase of the series.
* Avoid naming inconsistency between drm_sched_rq_add/remove. (Christian)

When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:
spin_lock(&entity->rq_lock);
spin_lock(&entity->rq->lock);
Rename drm_sched_entity.rq_lock to improve readability. While at it,
re-order that struct's members to make it more obvious what the lock
protects.
v2:
* Rename some rq_lock straddlers in kerneldoc, improve commit text. (Philipp)

Current kerneldoc for struct drm_sched_rq incompletely documents what
fields are protected by the lock.
This is not good because it is misleading.
Lets fix it by listing all the elements which are protected by the lock.
While at it, lets also re-order the members so all protected by the lock
are in a single group.
v2:
* Refer variables by kerneldoc syntax, more verbose commit text. (Philipp)

It does not seem there is a need to set the current entity in FIFO mode
since ot only serves as being a "cursor" in round-robin mode. Even if
scheduling mode is changed at runtime the change in behaviour is simply
to restart from the first entity, instead of continuing in RR mode from
where FIFO left it, and that sounds completely fine.

In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.
We can avoid that design inelegance, and also have a miniscule
efficiency improvement on the submit from idle path, by introducing a new
drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to
its callers.
v2:
* Remove drm_sched_rq_update_fifo() altogether. (Christian)
v3:
* Improved commit message. (Philipp)

DRM's aperture functions have long been implemented as helpers
under drivers/video/ for use with fbdev. Avoid the DRM wrappers by
calling the video functions directly.

Add basic support for the new AIC080 product. The PCIe Device ID is
0xa080. AIC080 is a lower cost, lower performance SKU variant of AIC100.
From the qaic perspective, it is the same as AIC100.

The ipc_router channel allows AF_QIPCRTR clients and services to
communicate with the AIC100 device. The ipc_router MHI transport layer
expects the channel to be named exactly "IPCR".

Although I don't hold expertise on the display side of VC4, I'd like to
help reviewing patches that are related to the 3D side of the VC4 driver.
As V3D maintainer, I hold some expertise with Broadcom GPUs and I'm
constantly testing kernels on RPi 3-5.

Use new HDMI Connector helpers in the Lontium LT9611 bridge driver.
Program InfoFrames using the helper's callbacks. Also use TMDS char rate
validation callback to filter out modes, instead of hardcoding 4k@30.
The Audio InfoFrame isn't yet handled by these helpers, it requires
additional drm_bridge interface changes.

When a display controller driver uses DRM_BRIDGE_ATTACH_NO_CONNECTOR,
tc358767 will behave properly and skip the creation of the connector.
However, tc_get_display_props(), which is used to find out about the DP
monitor and link, is only called from two places: .atomic_enable() and
tc_connector_get_modes(). The latter is only used when tc358767 creates
its own connector, i.e. when DRM_BRIDGE_ATTACH_NO_CONNECTOR is _not_
set.
Thus, the driver never finds out the link properties before get_edid()
is called. With num_lanes of 0 and link_rate of 0 there are not many
valid modes...
Fix this by adding tc_get_display_props() call at the beginning of
get_edid(), so that we have up to date information before looking at the
modes.

Currently vmwgfx uses the dev_private opaque pointer in drm_device to store
driver data in vmw_private struct. Using dev_private is deprecated, and the
recommendation is to embed struct drm_device in the larger per-device
structure.
The vmwgfx driver already embeds struct drm_device in its struct
vmw_private, so switch to using that exclusively and stop using
dev_private.
