From: Sylwester Nawrocki Date: Wed, 24 Aug 2011 23:35:30 +0000 (-0300) Subject: [media] s5p-fimc: Add subdev for the FIMC processing block X-Git-Tag: v3.2-rc1~112^2~196 X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=237e026559b7cd03fc575b6007cea11aef9e0aa6;p=~andy%2Flinux [media] s5p-fimc: Add subdev for the FIMC processing block Add a subdev to expose the host's scaling and composition functions. The camera frame composition onto an output buffer may be configured through set/get_crop at FIMC.{n} source pad. Additionally allow crop, composition and controls to be modified during streaming. Make sure the default format is set when opening the video capture node. Rename struct fimc_vid_cap::fmt to more relevant 'mf' to avoid confusion.
