From: Oliver O'Halloran <oohall@gmail.com> To: linuxppc-dev@lists.ozlabs.org Cc: linux-nvdimm@lists.01.org Subject: [RFC 1/4] libnvdimm: add to_{nvdimm,nd_region}_dev() Date: Tue, 27 Jun 2017 20:28:48 +1000 [thread overview] Message-ID: <20170627102851.15484-1-oohall@gmail.com> (raw) struct device contains the ->of_node pointer so that devices can be assoicated with the device-tree node that created them on DT platforms. libnvdimm hides the struct device for regions and nvdimm devices inside of an opaque structure so this patch adds accessors for each to allow the of_nvdimm driver to set the of_node pointer.
