| * media: Add registration helpers for V4L2 flash sub-devicesJacek Anaszewski2015-06-221-0/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds helper functions for registering/unregistering LED Flash class devices as V4L2 sub-devices. The functions should be called from the LED subsystem device driver. In case the support for V4L2 Flash sub-devices is disabled in the kernel config the functions' empty versions will be used.

| * v4l: async: Add a pointer to of_node to struct v4l2_subdev, match itSakari Ailus2015-06-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | V4L2 async sub-devices are currently matched (OF case) based on the struct device_node pointer in struct device. LED devices may have more than one LED, and in that case the OF node to match is not directly the device's node, but a LED's node.

* | [media] v4l2-dv-timings: add interlace support in detect cvt/gtfPrashant Laddha2015-06-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend detect_cvt/gtf API to indicate the format type (interlaced or progressive). In case of interlaced, the vertical front and back porch and vsync values for both (odd,even) fields are considered to derive image height. Populated vsync, vertical front, back porch values in bt timing structure for even and odd fields and updated the flags appropriately. Also modified the functions calling the detect_cvt/gtf(). As of now these functions are calling detect_cvt/gtf() with interlaced flag set to false.

It depends on a struct adv7842_output_format that does not exist. And besides that gcc has no support for bf609 so nobody can compile it except by installing a toolchain from ADI.

As well as updating the sysfs interface to know which wakeup protocols are allowed for encode_wakeup drivers, also ensure that the IR decoders/encoders are loaded when an encode_wakeup driver is registered.

* | [media] v4l: of: Parse variable length properties --- link-frequenciesSakari Ailus2015-04-271-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The link-frequencies property is a variable length array of link frequencies in an endpoint. The array is needed by an increasing number of drivers, so it makes sense to add it to struct v4l2_of_endpoint. However, the length of the array is variable and the size of struct v4l2_of_endpoint is fixed since it is allocated by the caller. The options here are 1. to define a fixed maximum limit of link frequencies that has to be the global maximum of all boards. This is seen as problematic since the maximum could be largish, and everyone hitting the problem would need to submit a patch to fix it, or 2. parse the property in every driver. This doesn't sound appealing as two of the three implementations submitted to linux-media were wrong, and one of them was even merged before this was noticed, or 3. change the interface so that allocating and releasing memory according to the size of the array is possible. This is what the patch does. v4l2_of_alloc_parse_endpoint() is just like v4l2_of_parse_endpoint(), but it will allocate the memory resources needed to store struct v4l2_of_endpoint and the additional arrays pointed to by this struct. A corresponding release function v4l2_of_free_endpoint() is provided to release the memory allocated by v4l2_of_alloc_parse_endpoint(). In addition to this, the link-frequencies property is parsed as well, and the result is stored to struct v4l2_of_endpoint field link_frequencies.

| * [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.

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

| * [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.
