Subject: [PATCH v4 8/8] powerpc/pmem: Initialize pmem device on newer hardware
Date: Fri, 29 May 2020 10:58:20 +0530 [thread overview]
Message-ID: <20200529052820.151651-9-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20200529052820.151651-1-aneesh.kumar@linux.ibm.com>
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"
