[PATCH V2 0/5] dmaengine: xilinx_dma: MCDMA descriptor and metadata handling improvements

[Srinivas Neeli <srinivas.neeli@amd.com>]

This series improves the Xilinx AXI MCDMA driver's descriptor handling
and metadata reporting. It fixes direction specific descriptor field
usage, ensures completion is based on the hardware completion bit
(important with delay interrupts), and extends metadata handling so APP
fields are used when the AXI4-Stream status/control interface is enabled.
When APP fields are unavailable, the series still reports transferred byte
count via the status field, enabling clients to track progress in both
configurations. Device tree bindings are updated to expose the
status/control stream presence with a dedicated property, distinct from
stream connectivity.

Changes in V2:
- Rebased on the AXI DMA binding YAML conversion.
- Added xlnx,include-stscntrl-strm in the YAML binding.
- Clarified cover letter to reflect metadata behavior with and without
  APP fields.
