Subject: [PATCH v5 10/10] powerpc/pmem: Initialize pmem device on newer hardware
Date: Wed, 10 Jun 2020 11:53:43 +0530 [thread overview]
Message-ID: <20200610062343.492293-11-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20200610062343.492293-1-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"
