[PATCH 0/4] DW DMAC: update device tree
From: Eugeniy Paltsev
Date: Wed Nov 16 2016 - 08:57:31 EST
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.
