[media] omap3isp: Platform data could be NULL

2015-04-02T19:39:14+00:00

Only check for call platform data callback functions if there's platform data. Also take care of a few other cases where the NULL pdata pointer could have been accessed, and remove the check for NULL dev->platform_data pointer. Removing the check for NULL dev->platform_data isn't strictly needed by the DT support but there's no harm from that either: the device now can be used without sensors, for instance.

[media] media: omap3isp: video: Use v4l2_get_timestamp()

Replace the open-coded copy by a function call. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] media: omap3isp: video: drop setting of vb2 buffer state to VB2_BUF_STATE_ACTIVE

2015-04-02T19:32:32+00:00

There isn't a need to assign the state of vb2_buffer to active as this is already done by the core. Signed-off-by: Lad, Prabhakar Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] media: omap3isp: video: Don't call vb2 mmap with queue lock held

2015-04-02T19:31:14+00:00

videobuf2 has long been subject to AB-BA style deadlocks due to the queue lock and mmap_sem being taken in different orders for the mmap operation. The problem has been fixed by making this operation callable without taking the queue lock, using an mmap_lock internal to videobuf2. The omap3isp driver still calls the mmap operation with the queue lock held, resulting in a potential deadlock. As the operation can now be called without locking the queue, fix it.

[media] omap3isp: Correctly set QUERYCAP capabilities

2015-01-21T23:09:11+00:00

device_caps in struct v4l2_capability were inadequately set in VIDIOC_QUERYCAP. Fix this. Without this a WARN_ON in the v4l2 core is triggered. This WARN_ON was added for kernel 3.19 exactly to detect these situations. Signed-off-by: Sakari Ailus Acked-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] platform: Make use of media_bus_format enum

2014-11-14T19:54:08+00:00

In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

[media] omap3isp: ccdc: Support the interlaced field orders at the CCDC output

The CCDC can interleave fields into a single buffer when writing to memory. Support it. Signed-off-by: Laurent Pinchart Tested-by: Enrico Butera Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: video: Validate the video node field order

[media] omap3isp: Default to progressive field order when setting the format

If the requested field order is not supported default to progressive as we can't guess how the user will configure the pipeline later on. Signed-off-by: Laurent Pinchart Tested-by: Enrico Butera Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
