[PATCH v2 0/3] drm/panfrost: Fix poweroff and sync IRQs for suspend

[AngeloGioacchino Del Regno]

This series contains a fast fix for the basic GPU poweroff functionality
and goes further by implementing interrupt masking and synchronization
before suspend.

For more information, please look at the conversation at [1], which
explains the regression seen with the poweroff commit and the initial
approaches taken to solve that.

Cheers!
