Subject: [PATCH V6 2/8] vfio: platform: determine reset capability
Date: Sat, 28 May 2016 18:01:12 -0400	[thread overview]
Message-ID: <1464472878-27176-3-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1464472878-27176-1-git-send-email-okaya@codeaurora.org>

Creating a new function to determine if this driver supports reset
function or not. This is an attempt to abstract device tree calls
from the rest of the code.
