| * [media] vb2: add allow_zero_bytesused flag to the vb2_queue structKamil Debski2015-04-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vb2: fix bytesused == 0 handling (8a75ffb) patch changed the behavior of __fill_vb2_buffer function, so that if bytesused is 0 it is set to the size of the buffer. However, bytesused set to 0 is used by older codec drivers as as indication used to mark the end of stream. To keep backward compatibility, this patch adds a flag passed to the vb2_queue_init function - allow_zero_bytesused. If the flag is set upon initialization of the queue, the videobuf2 keeps the value of bytesused intact in the OUTPUT queue and passes it to the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | V4L2 clocks, e.g. used by camera sensors for their master clock, do not have to be supplied by a different V4L2 driver, they can also be supplied by an independent source. In this case the standart kernel clock API should be used to handle such clocks. This patch adds support for such cases.

| * [media] omap3isp: Refactor device configuration structs for Device TreeSakari Ailus2015-04-021-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make omap3isp configuration data structures more suitable for consumption by the DT by separating the I2C bus information of all the sub-devices in a group and the ISP bus information from each other. The ISP bus information is made a pointer instead of being directly embedded in the struct. In the case of the DT only the sensor specific information on the ISP bus configuration is retained. The structs are renamed to reflect that. After this change the structs needed to describe device configuration can be allocated and accessed separately without those needed only in the case of platform data. The platform data related structs can be later removed once the support for platform data can be removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | The video and pad ops are duplicates, so get rid of the more limited video op. The whole point of the subdev API is to allow reuse of subdev drivers by bridge drivers. Having duplicate ops makes that much harder. We should never have allowed duplicate ops in the first place. A lesson for the future.

| * [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-231-20/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

| * [media] media: Fix DVB devnode representation at media controllerMauro Carvalho Chehab2015-02-131-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous provision for DVB media controller support were to define an ID (likely meaning the adapter number) for the DVB devnodes. This is just plain wrong. Just like V4L, DVB devices (and any other device node)) are uniquely identified via a (major, minor) tuple. This is enough to uniquely identify a devnode, no matter what API it implements. So, before we go too far, let's mark the old v4l, fb, dvb and alsa "devnode" info as deprecated, and just call it as "dev". We can latter add fields specific to each API if needed. As we don't want to break compilation on already existing apps, let's just keep the old definitions as-is, adding a note that those are deprecated at media-entity.h.

| | | | | | | | | | | | | | | | 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.
