Subject: [PATCH v3 6/6] drm/komeda: Expose side_by_side by sysfs/config_id
Date: Thu, 14 Nov 2019 08:37:58 +0000 [thread overview]
Message-ID: <20191114083658.27237-7-james.qian.wang@arm.com> (raw)
In-Reply-To: <20191114083658.27237-1-james.qian.wang@arm.com>
There are some restrictions if HW works on side_by_side, expose it via
config_id to user.
