[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 While the driver's hardware is obsolete, the cirrus driver is still one of the go-to modules to learn about writing a DRM driver.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
