Subject: [PATCH v2 0/4] gpu: host1x: add runtime pm support

This patch-set series adds runtime pm support for host1x,
gr2d & dc. It retains the current behaviour if CONFIG_PM_RUNTIME
is not enabled.

For host1x & gr2d, the clocks are now enabled in .probe
and disabled on its exit. This is needed for correct
init of hardware.

Additionally for gr2d, the clocks are also enabled when
a new work is submitted and disabled when the work is done.
Due to parent->child relations between host1x->gr2d,
this scheme also ends up in enabling & disabling host1x clock

For dc, the clocks are enabled in .probe and disabled in
.remove but via runtime pm instead of direct clock APIs.
