Subject: [PATCH RESEND 2/3] dmaengine: s3c24xx-dma: add support for the s3c2410 type of controller
Date: Fri, 11 Oct 2013 11:01:04 +0200 [thread overview]
Message-ID: <201310111101.04721.heiko@sntech.de> (raw)
In-Reply-To: <201310111059.19791.heiko@sntech.de>
The earliest variants of the dma controller did not contain support for
controlling clocks.
