Subject: [PATCH v2 2/9] drm: rcar-du: Pass the encoder DT node to rcar_du_encoder_init()
Date: Fri, 24 Oct 2014 12:58:08 +0000	[thread overview]
Message-ID: <1414155495-3979-3-git-send-email-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <1414155495-3979-1-git-send-email-laurent.pinchart+renesas@ideasonboard.com>

The encoder DT node will be needed to register an external HDMI encoder.
Pass it to the rcar_du_encoder_init() function to prepare for HDMI
support.
