[PATCH v3 0/4] drm/vc4: Add a load tracker

[Paul Kocialkowski <paul.kocialkowski@bootlin.com>]

Hi,

Here is a third iteration of the VC4 load tracking series, which was
initially developed by Boris Brezillon and that I have now taken over.

This new version aggregates a standalone patch adding a debugfs entry,
which was updated since its last revision. A new preliminary patch is
also introduced, which fixes underrun reports when reconfiguring the
display pipeline.

A detailed changelog is available on each patch when applicable.

Cheers,

Paul
