drm/simple-kms: Add drm_simple_encoder_{init,create}()
...
This patch makes the internal encoder implementation of the simple
KMS helpers available to drivers.
These simple-encoder helpers initialize an encoder with an empty
implementation. This covers the requirements of most of the existing
DRM drivers. A call to drm_simple_encoder_create() allocates and
initializes an encoder instance, a call to drm_simple_encoder_init()
initializes a pre-allocated instance.
v3:
* remove drm_simple_encoder_create(); not required yet
* provide more precise documentation
v2:
* move simple encoder to KMS helpers
* remove name argument; simplifies implementation
* don't allocate with devm_ interfaces; unsafe with DRM

drm/panel: simple: add panel-dpi support
...
The panel-dpi compatible is a fallback that
allows the DT to specify the timing.
When matching panel-dpi expect the device tree to include the
timing information for the display-panel.
Background for this change:
There are a lot of panels and new models hits the market very often.
It is a lost cause trying to chase them all and users of new panels
will often find them in situations that the panel they ues are not
supported by the kernel.
On top of this a lot of panels are customized based on customer
specifications.
Including the panel timing in the device tree allows for a simple
way to describe the actual HW and use this description in a generic
way in the kernel.
This allows uses of proprietary panels, or panels which are not
included in the kernel, to specify the timing in the device tree
together with all the other HW descriptions.
And thus, using the device tree it is then easy to add support
for an otherwise unknown panel.
The current support expect panels that do not require any
delays for prepare/enable/disable/unprepare.
Oleksandr Suvorov replied:
I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using
panel settings from the following patch:

if no external backlight is found, we register a subdriver
for the internal backlight.

The old implementation of placing planes on the CRTC while configuring
the planes was naive and relied on the order in which the planes were
configured, enabled, and disabled. The situation where a plane's zpos
was changed on the fly was completely broken. The usual symptoms of
this problem was scrambled display and a flood of sync lost errors,
when a plane was active in two layers at the same time, or a missing
plane, in case when a layer was accidentally disabled.
The rewrite takes a more straight forward approach when HW is
concerned. The plane positioning registers are in the CRTC (or
actually OVR) register space and it is more natural to configure them
in a one go when configuring the CRTC. To do this we need make sure we
have all the planes on the updated CRTCs in the new atomic state. The
untouched planes on CRTCs that need plane position update are added to
the atomic state in tidss_atomic_check().

dma-buf: add dynamic DMA-buf handling v15
...
On the exporter side we add optional explicit pinning callbacks. Which are
called when the importer doesn't implement dynamic handling, move notification
or need the DMA-buf locked in place for its use case.
On the importer side we add an optional move_notify callback. This callback is
used by the exporter to inform the importers that their mappings should be
destroyed as soon as possible.
This allows the exporter to provide the mappings without the need to pin
the backing store.
v2: don't try to invalidate mappings when the callback is NULL,
lock the reservation obj while using the attachments,
add helper to set the callback
v3: move flag for invalidation support into the DMA-buf,
use new attach_info structure to set the callback
v4: use importer_priv field instead of mangling exporter priv.
v5: drop invalidation_supported flag
v6: squash together with pin/unpin changes
v7: pin/unpin takes an attachment now
v8: nuke dma_buf_attachment_(map|unmap)_locked,
everything is now handled backward compatible
v9: always cache when export/importer don't agree on dynamic handling
v10: minimal style cleanup
v11: drop automatically re-entry avoidance
v12: rename callback to move_notify
v13: add might_lock in appropriate places
v14: rebase on separated locking change
v15: add EXPERIMENTAL flag, some more code comments

The plan is use have both shmem and virtual "vram" running
side-by-side in virtio-gpu. It looks like we'll eventually use
struct drm_gem_object as a base class, and we'll need to convert
to shmem and vram objects on the fly. As a first step, add a
virtio_gpu_is_shmem helper. Thanks to kraxel for suggesting this
approach on Gitlab.
