2017-06-06[media] pxa_camera: Fix incorrect test in the image size generationPetr Cvek
During the transfer from the soc_camera a test in pxa_mbus_image_size() got removed. Without it any PXA_MBUS_LAYOUT_PACKED format causes either the return of a wrong value (PXA_MBUS_PACKING_2X8_PADHI doubles the correct value) or EINVAL (PXA_MBUS_PACKING_NONE and PXA_MBUS_PACKING_EXTEND16). This was observed in an error from the ffmpeg (for some of the YUYV subvariants). This patch re-adds the same test as in soc_camera version.

2017-06-06[media] pxa_camera: Add remaining Bayer 8 formatsPetr Cvek
This patch adds Bayer 8 GBRG and RGGB support and move GRBG definition close to BGGR (so all Bayer 8 variants are together). No other changes are needed as the driver handles them as RAW data stream. The RGGB variant was tested in a modified OV9640 driver.

2017-05-18[media] pxa_camera: fix module remove codepath for v4l2 clockPetr Cvek
The conversion from soc_camera omitted a correct handling of the clock gating for a sensor. When the pxa_camera driver module was removed it tried to unregister clk, but this caused a similar warning: WARNING: CPU: 0 PID: 6740 at drivers/media/v4l2-core/v4l2-clk.c:278 v4l2_clk_unregister(): Refusing to unregister ref-counted 0-0030 clock! The clock was at time still refcounted by the sensor driver. Before the removing of the pxa_camera the clock must be dropped by the sensor driver. This should be triggered by v4l2_async_notifier_unregister() call which removes sensor driver module too, calls unbind() function and then tries to probe sensor driver again. Inside unbind() we can safely unregister the v4l2 clock as the sensor driver got removed. The original v4l2_clk_unregister() should be put inside test as the clock can be already unregistered from unbind(). If there was not any bound sensor the clock is still present. The codepath is practically a copy from the old soc_camera. The bug was tested with a pxa_camera+ov9640 combination during the conversion of the ov9640 from the soc_camera.

2016-10-24[media] media: platform: pxa_camera: add missing sensor power onRobert Jarzmik
During sensors binding, there is a window where the sensor is switched off, while there is a call it to set a new format, which can end up in an access to the sensor, especially an I2C based sensor. Remove this window by activating the sensor. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-10-21[media] platform: don't break long linesMauro Carvalho Chehab
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 $_; } </script> Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
