From d2642485d694027ad8c918844cee0e547cc11bcb Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Thu, 16 Feb 2012 14:23:54 -0300 Subject: [PATCH] [media] V4L: Add V4L2_MBUS_FMT_S5C_UYVY_JPEG_1X8 media bus format This patch adds media bus pixel code for the interleaved JPEG/UYVY image format used by S5C73MX Samsung cameras. This interleaved image data is transferred on MIPI-CSI2 bus as User Defined Byte-based Data. It also defines an experimental vendor and device specific media bus formats section and adds related DocBook documentation.
