Subject: [PATCH 8/9] drm/imx: enable/disable PRG on CRTC enable/disable
Date: Fri, 17 Feb 2017 19:28:29 +0100 [thread overview]
Message-ID: <20170217182830.32618-9-l.stach@pengutronix.de> (raw)
In-Reply-To: <20170217182830.32618-1-l.stach-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>
On i.MX6 QuadPlus the PRG needs to be clocked in order to pass
through the data access requests from the IDMAC. This call is a
no-op for other all other SoCs.
