[v2,0/5] drm/panthor: Misc fixes

Message

Boris Brezillon April 1, 2025, 6:23 p.m. UTC

Hello,

This is a collection of fixes for bugs found while working on adding
JM support to panthor. Those are not particularly tied to JM support
and are worth having regardless.

Note that the last two don't have Fixes tag because they fix issues
we can't really hit with the current implementation (no fault
handling, and no shared irq line).

Changelog available in each patch if you're interested.

Regards,

Boris
