"A bunch of new support and few updates to drivers:
New support:
- DMA_MEMCPY_SG support is bought back as we have a user in Xilinx
driver
- Support for TI J721S2 SoC in k3-udma driver
- Support for Ingenic MDMA and BDMA in the JZ4760
- Support for Renesas r8a779f0 dmac
Updates:
- We are finally getting rid of slave_id, so this brings in the
changes across tree for that
- updates for idxd driver
- at_xdmac driver cleanup"

The JZ4760 and JZ4760B SoCs have two additional DMA controllers: the
MDMA, which only supports memcpy operations, and the BDMA which is
mostly used for transfer between memories and the BCH controller.
The JZ4770 also features the same BDMA as in the JZ4760B, but does not
seem to have a MDMA.

The TI k3-bcdma and k3-pktdma both use 'ti,sci' and 'ti,sci-dev-id'
properties defined in ti,k3-sci-common.yaml. When 'unevaluatedProperties'
support is enabled, the follow warning is generated:
Documentation/devicetree/bindings/dma/ti/k3-bcdma.example.dt.yaml: dma-controller@485c0100: Unevaluated properties are not allowed ('ti,sci', 'ti,sci-dev-id' were unexpected)

Add a reference to ti,k3-sci-common.yaml to fix this.

In some configurations, the BAM DMA controller is set up by a remote
processor and the local processor can simply start making use of it
without setting up the BAM. This is already supported using the
"qcom,controlled-remotely" property.
However, for some reason another possible configuration is that the
remote processor is responsible for powering up the BAM, but we are
still responsible for initializing it (e.g. resetting it etc). Add
a "qcom,powered-remotely" property to describe that configuration.

Default REQ/ACK protocol consists in maintaining ACK signal up to the
removal of REQuest and the transfer completion.
In case of alternative REQ/ACK protocol, ACK de-assertion does not wait the
removal of the REQuest, but only the transfer completion.
Due to a possible DMA stream lock when transferring data to/from STM32
USART/UART, this new bindings allow to select this alternative protocol in
device tree, especially for STM32 USART/UART nodes.
