Hi,

These are a few trivial fixes and cleanups from playing with the
panfrost kernel driver on an Arm Juno board. Not that anyone has ever
cared much about the built-in GPU on Juno, but it's at least a somewhat
interesting platform from the kernel driver perspective for having
I/O coherency, RAM above 4GB, and DVFS abstracted behind a firmware
interface.

Robin.


Robin Murphy (4):
  drm/panfrost: Set DMA masks earlier
  drm/panfrost: Disable PM on probe failure
  drm/panfrost: Don't scream about deferred probe
  drm/panfrost: Show stored feature registers
