From: Manjunath Hadli Date: Wed, 28 Nov 2012 05:06:17 +0000 (-0300) Subject: [media] davinci: vpfe: dm365: add IPIPEIF driver based on media framework X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f7fa454dc1771155a2ceaf490e1dec9d4c2613bd;p=linux-beck.git [media] davinci: vpfe: dm365: add IPIPEIF driver based on media framework add support for dm365 IPIPEIF driver based on media framework. The IPIPEIF is exposed as a subdev, and it supports features like fault pixel correction, dark frame subtraction and other necessary hardware setup.
