Hi Vinod,

Thanks for having a look and providing the comments.

Is the .compatible documented, Documentation patch should come before
the driver use patch in a series

Yes, this new compatible string is documented in patch (05/10).
I would make it as a patch (1/10).

 static int owl_dma_probe(struct platform_device *pdev)
 {
      struct device_node *np = pdev->dev.of_node;
      struct owl_dma *od;
      int ret, i, nr_channels, nr_requests;
+     const struct of_device_id *of_id =
+                             of_match_device(owl_dma_match, &pdev->dev);

You care about driver_data rather than of_id, so using
of_device_get_match_data() would be better..

Okay. would take care of it in next version.

      if (!od)

Funny casts, I dont think you need uintptr_t!

But without this cast, clang compiler emits following warning:

warning: cast to smaller integer type 'enum owl_dma_id' from 'const void *'
          [-Wvoid-pointer-to-enum-cast]

Thanks
