Christophe JAILLET a5bc63f28a [media] soc-camera: Fix a return value in case of error
If 'ov9640_reg_read()' does not return 0, then 'val' is left unmodified.
As it is not initialized either, the return value can be anything.

It is likely that returning the error code was expected here.

Mauro Carvalho Chehab 8f44c39251 [media] soc_camera: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.

As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.

So, join those continuation lines.

The patch was generated via the script below, and manually
adjusted if needed.

</script>
use Text::Tabs;
while (<>) {
	if ($next ne "") {
		$c=$_;
		if ($c =~ /^\s+\"(.*)/) {
			$c2=$1;
			$next =~ s/\"\n$//;
			$n = expand($next);
			$funpos = index($n, '(');
			$pos = index($c2, '",');
			if ($funpos && $pos > 0) {
				$s1 = substr $c2, 0, $pos + 2;
				$s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2;
				$s2 =~ s/^\s+//;

				$s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne "");

				print unexpand("$next$s1\n");
				print unexpand("$s2\n") if ($s2 ne "");
			} else {
				print "$next$c2\n";
			}
			$next="";
			next;
		} else {
			print $next;
		}
		$next="";
	} else {
		if (m/\"$/) {
			if (!m/\\n\"$/) {
				$next=$_;
				next;
			}
		}
	}
	print $_;
}

Robert Jarzmik 5d7cc01b20 [media] media: mt9m111: make a standalone v4l2 subdevice
Remove the soc_camera adherence. Mostly the change removes the power
manipulation provided by soc_camera, and instead :
 - powers on the sensor when the s_power control is activated
 - powers on the sensor in initial probe
 - enables and disables the MCLK provided to it in power on/off

This patch also drops support for inverters on synchronisation and clock
lines. It is assumed, if any board ever needs such inverters, support
for them can be added in the future

Mauro Carvalho Chehab d647f0b70c [media] include/media: move driver interface headers to a separate dir
Let's not mix headers used by the core with those headers that
are needed by some driver-specific interface header.

The headers used on drivers were manually moved using:
    mkdir include/media/drv-intf/
    git mv include/media/cx2341x.h include/media/cx25840.h \
	include/media/exynos-fimc.h include/media/msp3400.h \

	include/media/si476x.h include/media/soc_mediabus.h \
	include/media/tea575x.h include/media/drv-intf/

And the references for those headers were corrected using:

    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="drv-intf/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do

Mauro Carvalho Chehab b5dcee225c [media] include/media: split I2C headers from V4L2 core
Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.

Let's move those i2c specific files to its own subdirectory.

The files to move were produced via the following script:
	mkdir include/media/i2c
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    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;

Commit 0ba2aeb6da increased the internal control ranges

control values in a division or modulus operations since not all architectures support
those natively.

Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

Guennadi Liakhovetski 9aea470b39 [media] soc-camera: switch I2C subdevice drivers to use v4l2-clk
Instead of centrally enabling and disabling subdevice master clocks in
soc-camera core, let subdevice drivers do that themselves, using the
V4L2 clock API and soc-camera convenience wrappers.

Paul Bolle b3d9a15d9a [media] soc_camera: remove two outdated selects
Release v2.6.30 removed the MT9M001_PCA9536_SWITCH and
MT9V022_PCA9536_SWITCH Kconfig symbols, in commits
36034dc325 ("V4L/DVB (11032): mt9m001:
allow setting of bus width from board code") and
e958e27ade ("V4L/DVB (11033): mt9v022:
allow setting of bus width from board code").
These two commits removed all gpio related code from these two drivers.
But they skipped removing their two selects of GPIO_PCA953X. Remove
these now as they are outdated. Their dependencies can never evaluate to
true anyhow.

Andrei Andreyanau bff7993936 [media] mt9v022 driver: send valid HORIZONTAL_BLANKING values to mt9v024 soc camera
This patch fixes the issue that appears when mt9v024 camera is used with the
mt9v022 soc camera driver. The minimum total row time is 690 columns
(horizontal width + horizontal blanking). The minimum horizontal
blanking is 61. Thus, when the window width is set below 627, horizontal blanking must
be increased. For the mt9v024 camera the values above are correct and
for the mt9v022 camera the correct values are in the existing kernel driver.

Guennadi Liakhovetski 4a1313c447 [media] mt9m111: fix Oops - initialise context before dereferencing
A recent commit "[media] soc-camera: Push probe-time power management to
drivers" causes an Oops during mt9m111 driver probing because its .ctx
private data field is now dereferenced before it is initialised. Fix this
by initialising the field earlier.

Benoît Thébaudeau cbaa5c54cb [media] soc-camera: mt9m111: Fix auto-exposure control
Commit f9bd584365 changed V4L2_CID_EXPOSURE_AUTO
from boolean to enum, and commit af8425c54b
changed the creation of this control into a menu for the mt9m111. However,
mt9m111_set_autoexposure() is still interpreting the value set for this control
as a boolean, which also conflicts with the default value of this control set to
V4L2_EXPOSURE_AUTO (0).
This patch makes mt9m111_set_autoexposure() interpret the value set for
V4L2_CID_EXPOSURE_AUTO as defined by enum v4l2_exposure_auto_type.

Guennadi Liakhovetski ec34e1d579 [media] mt9t112: mt9t111 format set up differs from mt9t112
The original commit, adding the mt9t112 driver said, that mt9t111 and
mt9t112 had identical register layouts. This however doesn't seem to be
the case. At least pixel format selection in the mt9t111 datasheet is
different from the driver implementation. So far only the default YUYV
format has been verified to work with mt9t111. Limit the driver to only
report one supported format with mt9t111 until more formats are
implemented.
