Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.
The headers were moved with:
mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/
And the references fixed with this script:
MAIN_DIR="linux/platform_data/"
PREV_DIR="media/"
DIRS="media/"
echo "Checking affected files" >&2
for i in $DIRS; do
for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
n=`basename $j`
git grep -l $n
done
done|sort|uniq >files && (
echo "Handling files..." >&2;
echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
(
cd include/$MAIN_DIR;
for j in $DIRS; do
for i in $(ls $j); do
echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
done;
done;
echo "cat > a && mv a \$i; done";
);
echo "Handling documentation..." >&2;
echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
(
cd include/$MAIN_DIR;
for j in $DIRS; do
for i in $(ls $j); do
echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
done;
done;
echo "cat > a && mv a \$i; done"
);
) >script && . ./script

OMAP4 ISS Driver
|
|
================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
|
|
Which contains several components that can be categorized in 3 big groups:
|
|
|
|
- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
|
|
- ISP (Image Signal Processor)
|
|
- SIMCOP (Still Image Coprocessor)
|
|
|
|
For more information, please look in [1] for latest version of:
|
|
"OMAP4430 Multimedia Device Silicon Revision 2.x"
|
|
|
|
As of Revision AB, the ISS is described in detail in section 8.
|
|
|
|
This driver is supporting _only_ the CSI2-A/B interfaces for now.
|
|
|
|
It makes use of the Media Controller framework [2], and inherited most of the
|
|
code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*),
|
|
except that it doesn't need an IOMMU now for ISS buffers memory mapping.
|
|
|
|
Supports usage of MMAP buffers only (for now).
|
|
|
|
Tested platforms
|
|
----------------
|
|
|
|
- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
|
|
which only the last one is supported, outputting YUV422 frames).
|
|
|
|
- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
|
|
which only the OV5650 are supported, outputting RAW10 frames).
|
|
|
|
- PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with
|
|
following sensors:
|
|
* OV5640
|
|
* OV5650
|
|
|
|
- Tested on mainline kernel:
