fe5040f284
dt-bindings: sun6i-dsi: Document A64 MIPI-DSI controller 
The MIPI DSI controller in Allwinner A64 is similar to A33.

But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to have separate compatible for A64 on the same driver.

DSI_SCLK uses mod clock-names on dt-bindings, so the same
is not required for A64.

On that note
- A64 require minimum of 1 clock like the bus clock
- A33 require minimum of 2 clocks like both bus, mod clocks

So, update dt-bindings so-that it can document both A33,
A64 bindings requirements.

  next for a while outside of my tree so shouldn't cause any unexpected
  issues, it has some OCMEM support in drivers/soc that is acked by
  other maintainers as it's outside my tree.

  Otherwise it's a usual fixes pull, i915, amdgpu, the main ones, with
  some tegra, omap, mgag200 and one core fix.

  Summary:

  msm-next:
   - OCMEM support for a3xx and a4xx GPUs.
   - a510 support + display support

  core:
   - mst payload deletion fix

  i915:
   - uapi alignment fix
   - fix for power usage regression due to security fixes
   - change default preemption timeout to 640ms from 100ms
   - EHL voltage level display fixes
   - TGL DGL PHY fix
   - gvt - MI_ATOMIC cmd parser fix, CFL non-priv warning
   - CI spotted deadlock fix
   - EHL port D programming fix

  amdgpu:
   - VRAM lost fixes on BACO for CI/VI
   - navi14 DC fixes
   - misc SR-IOV, gfx10 fixes
   - XGMI fixes for arcturus
   - SRIOV fixes

  amdkfd:
   - KFD on ppc64le enabled
   - page table optimisations

  radeon:
   - fix for r1xx/2xx register checker.

  tegra:

Here is the "big" tty and serial driver patches for 5.5-rc1.  It's a bit
 later in the merge window than normal as I wanted to make sure some
 last-minute patches applied to it were all sane.  They seem to be :)
 
 There's a lot of little stuff in here, for the tty core, and for lots of
 serial drivers:
 	- reverts of uartlite serial driver patches that were wrong
 	- msm-serial driver fixes
 	- serial core updates and fixes
 	- tty core fixes
 	- serial driver dma mapping api changes
 	- lots of other tiny fixes and updates for serial drivers
 
 All of these have been in linux-next for a while with no reported

Pull irq updates from Ingo Molnar:
 "Most of the IRQ subsystem changes in this cycle were irq-chip driver
  updates:

   - Qualcomm PDC wakeup interrupt support

   - Layerscape external IRQ support

   - Broadcom bcm7038 PM and wakeup support

   - Ingenic driver cleanup and modernization

   - GICv3 ITS preparation for GICv4.1 updates

   - GICv4 fixes

  There's also the series from Frederic Weisbecker that fixes memory
  ordering bugs for the irq-work logic, whose primary fix is to turn
  work->irq_work.flags into an atomic variable and then convert the
  complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a
  much simpler atomic_fetch_or() call.

  There are also various smaller cleanups"

 NCR5380, lpfc, qla2xxx, smartpqi, hisi_sas, target, mpt3sas, pm80xx
 plus a whole load of minor updates and fixes.  The two major core

937d6eefc7 Here's the main documentation changes for 5.5: 
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

1daa56bcfd IOMMU Updates for Linux v5.5 
Including:
 
 	- Conversion of the AMD IOMMU driver to use the dma-iommu code
 	  for imlementing the DMA-API. This gets rid of quite some code
 	  in the driver itself, but also has some potential for
 	  regressions (non are known at the moment).
 
 	- Support for the Qualcomm SMMUv2 implementation in the SDM845
 	  SoC.  This also includes some firmware interface changes, but
 	  those are acked by the respective maintainers.
 
 	- Preparatory work to support two distinct page-tables per
 	  domain in the ARM-SMMU driver
 
 	- Power management improvements for the ARM SMMUv2
 
 	- Custom PASID allocator support
 
 	- Multiple PCI DMA alias support for the AMD IOMMU driver
 
 	- Adaption of the Mediatek driver to the changed IO/TLB flush
 	  interface of the IOMMU core code.
 
 	- Preparatory patches for the Renesas IOMMU driver to support
 	  future hardware.

Merge tag 'iommu-updates-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates from Joerg Roedel:

 - Conversion of the AMD IOMMU driver to use the dma-iommu code for
   imlementing the DMA-API. This gets rid of quite some code in the
   driver itself, but also has some potential for regressions (non are
   known at the moment).

 - Support for the Qualcomm SMMUv2 implementation in the SDM845 SoC.
   This also includes some firmware interface changes, but those are
   acked by the respective maintainers.

 - Preparatory work to support two distinct page-tables per domain in
   the ARM-SMMU driver

 - Power management improvements for the ARM SMMUv2

 - Custom PASID allocator support

 - Multiple PCI DMA alias support for the AMD IOMMU driver

 - Adaption of the Mediatek driver to the changed IO/TLB flush interface
   of the IOMMU core code.

 - Preparatory patches for the Renesas IOMMU driver to support future
   hardware.
