Why add a new if based on direction?
You can use the one below, from line 765.

…resses The DMAC has the same view of the address space as the HOST. As such, the source and destination addresses need to be converted to HOST-relative addresses before attempting to perform a DMA transfer. This is only relevant for platforms for which the DSP and HOST have different views of the address space (e.g: i.MX8ULP). Also, if a platform doesn't define the `local_to_host` macro (used for converting DSP local address to HOST-relative address) we assume that the HOST and the DSP have the same view of the address space. As such, we also add a definition of `local_to_host` which will just return the passed address. Signed-off-by: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>
