[PATCH v7 7/7] powerpc/pmem: Initialize pmem device on newer hardware

From: Aneesh Kumar K.V <hidden>
Date: 2020-07-01 07:38:47
Also in: nvdimm
Subsystem: libnvdimm: devicetree bindings, libnvdimm: non-volatile memory device subsystem, linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Oliver O'Halloran, Dan Williams, Vishal Verma, Dave Jiang, Alison Schofield, Madhavan Srinivasan, Linus Torvalds

With kernel now supporting new pmem flush/sync instructions, we can now
enable the kernel to initialize the device. On P10 these devices would
appear with a new compatible string. For PAPR device we have

compatible       "ibm,pmemory-v2"

and for OF pmem device we have

compatible       "pmem-region-v2"
