From: Dominic Curran <dcurran@xxxxxx>
Subject: [OMAPZOOM][PATCH 2/3] ISP: Add CCDC offset info to board file.
Adds new enums which signal what component order CCDC input should expect:
ISPCCDC_INPUT_FMT_GR_BG
ISPCCDC_INPUT_FMT_RG_GB
ISPCCDC_INPUT_FMT_BG_GR
ISPCCDC_INPUT_FMT_GB_RG
These are set per sensor, and the setup has been moved to the board files.
This enum value is then passed to CCDC which turns it into a horiz/vert offset
that will set the register fields:
ISPCCDC_FMT_HORZ.ISPCCDC_FMT_HORZ_FMTSPH_SHIFT
ISPCCDC_FMT_VERT.ISPCCDC_FMT_VERT_FMTSLV_SHIFT
This patch causes the CCDC output component order to be consistent for all
sensors regardless of the input order.
