Hi folks,

This series adds support for the Mali450 MP4 GPU found on the
hi6220 SoC from HiSilicon. It has been tested with the
lima drm/mesa driver hosted on freedesktop.org gitlab,
and validated using Weston and kmscube.

As lima drm driver has now been merged this v2 series includes
one extra patch to avoid Oops when all Mali ip blocks share the
same irq.

regards,

Peter.

Changes since v1:
* Additional drm/lima patch to avoid Oops in shared irq case (Peter Griffin)
* Squash clock and reset driver parts to avoid bisection hole (Stephen Boyd)
* Add comment as to what other driver is probing same dt node (Stephen Boyd)
* Check regmap_write error code and return individually (Philipp Zabel)
* Add Rob Herring Reviewed by tags
