Subject: [PATCH v2 6/6] cxlflash: Enable device id for future IBM CXL adapter
Date: Mon, 14 Dec 2015 15:07:43 -0600	[thread overview]
Message-ID: <1450127263-48261-1-git-send-email-ukrishn@linux.vnet.ibm.com> (raw)
In-Reply-To: <1450126293-47440-1-git-send-email-ukrishn@linux.vnet.ibm.com>

From: Manoj Kumar <manoj@linux.vnet.ibm.com>

This drop enables a future card with a device id
of 0x0600 to be recognized by the cxlflash driver.

As per the design, the Accelerator Function Unit (AFU)
for this new IBM CXL Flash Adapter retains the same
host interface as the previous generation. For the early
prototypes of the new card, the driver with this change
behaves exactly as the driver prior to this behaved with
the earlier generation card. Therefore, no card specific
programming has been added. These card specific changes
can be staged in later if needed.
