37256335bd dt-bindings: dmaengine: dma-common: Fix the dma-channel-mask property
The commit b37e3534ac ("dt-bindings: dmaengine: Add YAML schemas
for the generic DMA bindings") changed the property from
dma-channel-mask to dma-channel-masks. So, this patch fixes it.

Rename the device tree bindings for renesas "Type-AXI" NBPFAXI* DMA
controllers from nbpfaxi.txt to renesas,nbpfaxi.txt.

Renesas IP blocks consistently, in line with the compat strings they

edd14218bd dt-bindings: dmaengine: Convert Allwinner A31 and A64 DMA to a schema
The newer Allwinner SoCs have a DMA controller supported in Linux, with a

Now that we have the DT validation in place, let's convert the device tree

af6af87d7e ARM: Device-tree updates
We continue to see a lot of new material. I've highlighted some of it
 below, but there's been more beyond that as well.
 
 One of the sweeping changes is that many boards have seen their ARM Mali
 GPU devices added to device trees, since the DRM drivers have now been
 merged.
 
 So, with the caveat that I have surely missed several great
 contributions, here's a collection of the material this time around:
 
 New SoCs:
 
  - Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
 
  - TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
 
  - Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
 
 New Boards / platforms:
 
  - Aspeed BMC support for a number of new server platforms
 
  - Kontron SMARC SoM (several i.MX6 versions)
 
  - Novtech's Meerkat96 (i.MX7)
 
  - ST Micro Avenger96 board
 
  - Hardkernel ODROID-N2 (Amlogic G12B)
 
  - Purism Librem5 devkit (i.MX8MQ)
 
  - Google Cheza (Qualcomm SDM845)
 
  - Qualcomm Dragonboard 845c (Qualcomm SDM845)
 
  - Hugsun X99 TV Box (Rockchip RK3399)
 
  - Khadas Edge/Edge-V/Captain (Rockchip RK3399)
 
 Updated / expanded boards and platforms:
 
  - Renesas r7s9210 has a lot of new peripherals added
 
  - Polish and fixes for Rockchip-based Chromebooks
 
  - Amlogic G12A has a lot of peripherals added
 
  - Nvidia Jetson Nano sees various fixes and improvements, and is now at
    feature parity with TX1

For Spreadtrum DMA engine, all channels are equal, which means slave can

Thus we can remove the channel id from device tree to assign the channel
dynamically, moreover we should add the slave id in device tree.

The commit a9ddb575d6

   ("dmaengine: dw_dmac: Enhance device tree support")

introduces is_private property in uncertain understanding what does it mean.

First of all, documentation defines DMA_PRIVATE capability as

Documentation/crypto/async-tx-api.txt:
  The DMA_PRIVATE capability flag is used to tag dma devices that should not be
  used by the general-purpose allocator. It can be set at initialization time
  if it is known that a channel will always be private. Alternatively,
  it is set when dma_request_channel() finds an unused "public" channel.

  A couple caveats to note when implementing a driver and consumer:
  1/ Once a channel has been privately allocated it will no longer be
     considered by the general-purpose allocator even after a call to
     dma_release_channel().
  2/ Since capabilities are specified at the device level a dma_device with
     multiple channels will either have all channels public, or all channels
     private.

Documentation/driver-api/dmaengine/provider.rst:
  - DMA_PRIVATE
    The devices only supports slave transfers, and as such isn't available
    for async transfers.

The capability had been introduced by the commit 59b5ec2144

  ("dmaengine: introduce dma_request_channel and private channels")

and some code didn't changed from that times ever.

Taking into consideration above and the fact that on all known platforms
Synopsys DesignWare DMA engine is attached to serve slave transfers,
the DMA_PRIVATE capability must be enabled for this device unconditionally.
Otherwise, as rightfully noticed in drivers/dma/at_xdmac.c:
  /*
   * Without DMA_PRIVATE the driver is not able to allocate more than
   * one channel, second allocation fails in private_candidate.
   */
because of of a caveats mentioned in above documentation excerpts.

So, remove conditional around DMA_PRIVATE followed by removal leftovers.

If someone wonders, DMA_PRIVATE can be not used if and only if the all channels
of the DMA controller are supposed to serve memory-to-memory like operations.
For example, EP93xx has two controllers, one of which can only perform
memory-to-memory transfers

Note, this change doesn't affect dmatest to be able to test such controllers.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.
