Date: Thu, 8 Dec 2011 09:15:42 +0100 From: Lothar Waßmann <LW@...O-electronics.de> To: Vinod Koul <vinod.koul@...el.com> Cc: Huang Shijie <b32955@...escale.com>, Wolfram Sang <w.sang@...gutronix.de>, linux-kernel@...r.kernel.org, Lothar Waßmann <LW@...O-electronics.de> Subject: [PATCH 2/4] dma: mxs-dma: Always leave mxs_dma_init() with the clock disabled. There is no need to have the clock enabled all the time the driver is loaded. It will be enabled anyway in mxs_dma_alloc_chan_resources() when a channel is actually going to be used.
