From: Fabio Estevam Date: Fri, 28 Jun 2013 16:55:30 +0000 (-0300) Subject: imx-drm: ipu-dp: Introduce IPUV3_NUM_FLOWS X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6fe9a899edc8c145e6ba6d8217f95cf23932f999;p=openwrt%2Fstaging%2Fblogic.git imx-drm: ipu-dp: Introduce IPUV3_NUM_FLOWS IPUv3 has a total of 3 flows (one synchronous flow and 2 asynchronous flows). Let's add a definition for such number in order to let the code easier to understand.
