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

Boris Brezillon (5):
  drm/panthor: Fix GPU_COHERENCY_ACE[_LITE] definitions
  drm/panthor: Call panthor_gpu_coherency_init() after PM resume()
  drm/panthor: Update panthor_mmu::irq::mask when needed
  drm/panthor: Let IRQ handlers clear the interrupts themselves
  drm/panthor: Don't update MMU_INT_MASK in panthor_mmu_irq_handler()
