Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

  Summary:

   - 64-bit dma-fence seqno comparison fixes
   - move initial fb config code to core
   - gem fence array helpers for Lima
   - ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
   - lease fixes

drm/tegra: Changes for v5.2-rc1

This contains a fix for the usage of shared resets that previously
generated a WARN on boot. In addition, there's a fix for CPU cache
maintenance of GEM buffers allocated using get_pages().

(airlied: contains a merge from a shared tegra tree)

<title>drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()</title>

<content type='text'>
The allocated pages need to be invalidated in CPU caches. On ARM32 the
DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and
the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures
that the corresponding CPU cache lines are getting invalidated and nothing
more, that's exactly what is needed for a newly allocated pages.

This fixes randomly failing rendercheck tests on Tegra30 using the
Opentegra driver for tests that use small-sized pixmaps (10x10 and less,
i.e. 1-2 memory pages) because apparently CPU reads out stale data from
caches and/or that data is getting evicted to DRAM at the time of HW job
execution.

<title>drm/tegra: hdmi: Setup audio only if configured</title>

<content type='text'>
The audio configuration is only valid if the HDMI codec has been
properly set up. Do not attempt to set up audio before that happens
because it causes a division by zero.

Note that this is only problematic on Tegra20 and Tegra30. Later chips
implement the division instructions which return zero when dividing by
zero and don't throw an exception.

<title>drm/tegra: sor: Implement acquire/release for reset</title>

By implementing the acquire/release protocol, the SOR reset can be
shared with other drivers that also adhere to this protocol, such as the
PMC driver that uses the same reset as part of the powergate and -ungate
implementation using generic power domains.

Runtime PM makes sure that the operations are executed in the right
order, and the reset core has error handling and WARNs in place to make
sure the acquire/release protocol is followed.
