[PATCH 00/17] cirrus: Modernize the cirrus driver
Update the cirrus driver to follow current best practices. While the
driver's hardware is obsolete, the cirrus driver is still one of the
go-to modules to learn about writing a DRM driver. So keep it in good
shape.
Patches 1 to 3 simplify blitting and convert it to the DRM's current
helpers.
Patches 4 to 8 replace simple-KMS helpers with DRM's regular atomic
helpers. The former are

[PATCH 36/59] drm/cirrus: Don't use drm_device->dev_private
Upcasting using a container_of macro is more typesafe, faster and
easier for the compiler to optimize.

[PATCH] drm/cirrus: rewrite and modernize driver.
Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by

[PATCH v4] drm/cirrus: add drm_driver.release callback.
Move final cleanups from cirrus_pci_remove() to the new callback.
Add drm_atomic_helper_shutdown() call to cirrus_pci_remove().
Use drm_dev_{enter,exit,unplug} to avoid touching hardware after
device removal.
v4: add changelog.
v3: use drm_dev*.
v2: stop touching hardware after pci_remove().

[PATCH v2] drm/cirrus: add drm_driver.release callback.
Move final cleanups from cirrus_pci_remove() to the new callback.
Add drm_atomic_helper_shutdown() call to cirrus_pci_remove().
Set pointers to NULL after iounmap() and check them before using
them to make sure we don't touch released hardware.

[PATCH 5/5] drm: Don't pass clip to drm_atomic_helper_check_plane_state()
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Move the plane clip rectangle handling into
drm_atomic_helper_check_plane_state(). Drivers no longer
have to worry about such mundane details.
v2: Convert armada, rcar, and sun4i as well

[PATCH] drm/simple-kms: Standardize arguments for callbacks
Passing the wrong type feels icky, everywhere else we use the pipe as
the first parameter. Spotted while discussing patches with Thomas

[v3 PATCH 0/3] Allow ASYNC flip with atomic helpers.
This series is a folow-up on
https://patchwork.kernel.org/patch/9501787/
The first patch makes changes to atomic helpers to allow for
drives with ASYNC flip support to use them.
Patch 2 is to use this in AMDGPU/DC.
Patch 3 is possible cleanup in nouveau/kms who seems to have to duplicate
the helper as we did to support ASYNC flips.
v2:
Resend drm/atomic: Save flip flags in drm_plane_state
