It wasn't possible to enable some features like memory-to-memory transfers or multi block transfers via DT. It is fixed by these patches. * Rename is_private to is-private as ordered by DT policy. (just for cleanup) The change leaves the support for the old format. * Add is-memcpu property, so it is possible to enable memory-to-memory transfers support via DT. * Add hw-llp property, so it is possible to enable hardware multi block transfers support via DT. * Update DW DMAC device tree documentation.
