The existing APIs for requesting TX and RX DMA channels rely on parsing a device-tree node to obtain the Channel/Thread IDs from their names. However, it is possible to know the thread IDs by alternative means such as being informed by Firmware on a remote core regarding the allocated TX/RX DMA channel IDs. Thus, add APIs to support such use cases. Series is based on linux-next tagged next-20231110. Regards, Siddharth.
