From: Laurent Pinchart Date: Wed, 31 Aug 2011 14:57:12 +0000 (-0300) Subject: [media] omap3isp: video: Split format info bpp field into width and bpp X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1697e49a0b8c0ced14015b3f830cdd90c79c75b4;p=openwrt%2Fstaging%2Fblogic.git [media] omap3isp: video: Split format info bpp field into width and bpp The bpp field currently stores the sample width and is aligned to the next multiple of 8 bits when computing data size in memory. This won't work anymore for YUYV8_2X8 formats. Split the bpp field into a sample width and a bytes per pixel value.
