From 05ad6fc1d54f106d5b8c598e2f9b59b12f3fb476 Mon Sep 17 00:00:00 2001 From: Manjunath Hadli Date: Thu, 18 Oct 2012 07:58:02 -0300 Subject: [PATCH] [media] v4l2: add new pixel formats supported on dm365 add new macro V4L2_PIX_FMT_SGRBG10ALAW8 and associated formats to represent Bayer format frames compressed by A-LAW algorithm, add V4L2_PIX_FMT_UV8 to represent storage of CbCr data (UV interleaved) only.
