Switch all media platform drivers to call v4l2_async_notifier_add_subdev() to add asd's to a notifier, in place of referencing the notifier->subdevs[] array. These drivers also must now call v4l2_async_notifier_init() before adding asd's to their notifiers. There may still be cases where a platform driver maintains a list of asd's that is a duplicate of the notifier asd_list, in which case its possible the platform driver list can be removed, and can reference the notifier asd_list instead. One example of where a duplicate list has been removed in this patch is xilinx-vipp.c. If there are such cases remaining, those drivers should be optimized to remove the duplicate platform driver asd lists. None of the changes to the platform drivers in this patch have been tested. Verify that the async subdevices needed by the platform are bound at load time, and that the driver unloads and reloads correctly with no memory leaking of asd objects.

When the subdevice doesn't provide s_power core ops callback, the v4l2_subdev_call for s_power returns -ENOIOCTLCMD. If the subdevice doesn't have the special handling for its power saving mode, the s_power isn't required. So -ENOIOCTLCMD from the v4l2_subdev_call should be ignored. Actually the -ENOIOCTLCMD is ignored in this driver's suspend/resume, but the others treat the -ENOIOCTLCMD as an error. This prepares a wrapper function to ignore -ENOIOCTLCMD and replaces all s_power calls with it. This also adds warning message when s_power() is failed.

Akinobu Mita authored
The open() operation for the pxa_camera driver always calls s_power() operation to put its subdevice sensor in normal operation mode, and the release() operation always call s_power() operation to put the subdevice in power saving mode. This requires the subdevice sensor driver to keep track of its power state in order to avoid putting the subdevice in power saving mode while the device is still opened by some users. Many subdevice drivers handle it by the boilerplate code that increments and decrements an internal counter in s_power() like below: /* * If the power count is modified from 0 to != 0 or from != 0 to 0, * update the power state. */ if (sensor->power_count == !on) { ret = ov5640_set_power(sensor, !!on); if (ret) goto out; } /* Update the power count. */ sensor->power_count += on ? 1 : -1; However, some subdevice drivers don't handle it and may cause a problem with the pxa_camera driver if the video device is opened by more than two users at the same time. Instead of propagating the boilerplate code for each subdevice driver that implement s_power, this introduces an trick that many V4L2 drivers are using with v4l2_fh_is_singular_file().

The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME match criteria requires just a device name. So, it doesn't make sense to enclose those into structs, as the criteria can go directly into the union. That makes easier to document it, as we don't need to document weird senseless structs. At drivers, this makes even clearer about the match criteria.

The async subdev notifier .bound(), .unbind() and .complete() operations are function pointers stored directly in the v4l2_async_subdev structure. As the structure isn't immutable, this creates a potential security risk as the function pointers are mutable. To fix this, move the function pointers to a new v4l2_async_subdev_operations structure that can be made const in drivers.

In 'commit 295ab497 ("[media] media: platform: pxa_camera: make printk consistent")' a pointer to the device structure in mclk_get_divisor() was changed to pcdev_to_dev(pcdev). The pointer used by pcdev_to_dev() is still uninitialized during the call to mclk_get_divisor() as it happens in v4l2_device_register() at the end of the probe.

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.

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>

This patch removes the soc_camera API dependency from pxa_camera. In the current status : - all previously captures are working the same on pxa270 - the s_crop() call was removed, judged not working (see what happens soc_camera_s_crop() when get_crop() == NULL) - if the pixel clock is provided by then sensor, ie. not MCLK, the dual stage change is not handled yet. => there is no in-tree user of this, so I'll let it that way - the MCLK is not yet finished, it's as in the legacy way, ie. activated at video device opening and closed at video device closing. In a subsequence patch pxa_camera_mclk_ops should be used, and platform data MCLK ignored. It will be the sensor's duty to request the clock and enable it, which will end in pxa_camera_mclk_ops.

This is to be seen as a regression as the set_selection (former set_crop) function is removed. This is a temporary situation in the v4l2 porting, and will have to be added later.
