From: Sylwester Nawrocki Date: Fri, 27 May 2011 16:12:23 +0000 (-0300) Subject: [media] s5p-fimc: Adjust pixel height alignments according to the IP revision X-Git-Tag: v3.2-rc7~4^2~21 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9c63afcb02b4313838d83c3660e45544d9fc9976;p=platform%2Fupstream%2Fkernel-adaptation-pc.git [media] s5p-fimc: Adjust pixel height alignments according to the IP revision Minimum vertical pixel size alignment for input and output DMA and the scaler depend on color format, rotation, the IP instance and revision. Make vertical pixel size of format and crop better fit for each SoC revision and the IP instance by adding min_vsize_align attribute to the FIMC variant data structure. It's now common for the DMA engines and the scaler.
