Merge v5.16-rc5 into drm-next

2021-12-14T09:24:28Z

Thomas Zimmermann requested a fixes backmerge, specifically also for 96c5f82ef0a1 ("drm/vc4: fix error code in vc4_create_object()") Just a bunch of adjacent changes conflicts, even the big pile of them in vc4. Signed-off-by: Daniel Vetter

treewide: Add missing includes masked by cgroup -> bpf dependency

2021-12-03T18:58:13Z

cgroup.h (therefore swap.h, therefore half of the universe) includes bpf.h which in turn includes module.h and slab.h. Since we're about to get rid of that dependency we need to clean things up. v2: drop the cpu.h include from cacheinfo.h, it's not necessary and it makes riscv sensitive to ordering of include files.

drm/lima: Clean up redundant pdev pointer

There's no point explicitly tracking the platform device when it can be trivially derived from the regular device pointer in the couple of places it's ever used.

drm/lima: Clean up IRQ warnings

2020-04-24T12:47:00Z

Use the optional form of platform_get_irq() for blocks that legitimately may not be present, to avoid getting an annoying barrage of spurious warnings for non-existent PPs on configurations like Mali-450 MP2.

drm/lima: Add optional devfreq and cooling device support

2020-03-28T08:29:46Z

Most platforms with a Mali-400 or Mali-450 GPU also have support for changing the GPU clock frequency. Add devfreq support so the GPU clock rate is updated based on the actual GPU usage when the "operating-points-v2" property is present in the board.dts. The actual devfreq code is taken from panfrost_devfreq.c and modified so it matches what the lima hardware needs: - a call to dev_pm_opp_set_clkname() during initialization because there are two clocks on Mali-4x0 IPs. "core" is the one that actually clocks the GPU so we need to control it using devfreq. - locking when reading or writing the devfreq statistics because (unlike than panfrost) we have multiple PP and GP IRQs which may finish jobs concurrently.
