Subject: [PATCH v5 10/10] powerpc/pmem: Initialize pmem device on newer hardware

From: "Aneesh Kumar K.V" <[email-masked]>
Date: Wed, 10 Jun 2020 11:53:43 +0530

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"
