[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driver's hardware is obsolete, the cirrus driver is still one of the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
