Subject: [PATCH 10/11] drm/sun4i: Add backend pointer to sun4i_layer
Date: Thu, 23 Feb 2017 16:05:42 +0800	[thread overview]
Message-ID: <20170223080543.6659-11-wens@csie.org> (raw)
In-Reply-To: <20170223080543.6659-1-wens@csie.org>

sun4i_layer only controls the backend hardware block of the display
pipeline. Instead of getting a pointer to the underlying backend
through the drm_device structure, leave one in itself.

Also drop the drm_device pointer, since it is no longer needed.

The next step forward would be to pass the pointer in through
sun4i_layers_init as a parameter. This would make it easier to support
multiple display pipelines layer on.
