[RESEND PATCH] dmaengine: dw-edma: Add HDMA NATIVE map check

Posted by Devendra K Verma 9 months, 2 weeks ago

The HDMA IP supports the HDMA_NATIVE map format as part of Vendor-Specific
Extended Capability. Added the check for HDMA_NATIVE map format.
The check for map format enables the IP specific function invocation
during the DMA ops.

You also need to update the 'Debug info' part in dw_edma_pcie_probe().
