Subject: [PATCH v6 8/8] powerpc/pmem: Initialize pmem device on newer hardware
Date: Mon, 29 Jun 2020 19:27:22 +0530 [thread overview]
Message-ID: <20200629135722.73558-9-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20200629135722.73558-1-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"
Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com>
