* [media] r820t: add support for R828DAntti Palosaari2013-10-311-9/+13
| | | | | | | | | | | | | | | | Small changes in order to support tuner version R828D @ 16 MHz clock. There was 'vco_fine_tune' check, which seems to adjust synthesizer output divider (mixer dix / LO div / Rout) by one. R828D seems to return vco_fine_tune=1 every time and that condition causes tuning fail as output divider was increased by one. Resolve problem by skipping whole condition in case of R828D tuner. Just to mention, other tuner, R820T, seems to return 2 here. Synthesizer maximum frequency check was hard coded to check synthesizer N and thus worked correctly only for clock frequencies around 30 MHz. As whole test is quite useless in any case, I removed it totally. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] V4L2: em28xx: tell the ov2640 driver to balance clock enabling ↵Guennadi Liakhovetski2013-10-311-0/+1
| | | | | | | | | | | | | | | internally The em28xx driver only calls subdevices' .s_power() method to power them down, relying on the hardware to wake up automatically, which is usually the case with tuners. This was acceptable with the old .standby() method, but is wrong with .s_power(). Fixing the driver would be difficult due to a broad supported hardware base. Instead this patch makes use of the unbalanced_power soc-camera subdevice flag to tell the ov2640 driver to balance calls to v4l2_clk_enable() and v4l2_clk_disable() internally.

* [media] V4L2: soc-camera: work around unbalanced calls to .s_power()Guennadi Liakhovetski2013-10-312-6/+30
| | | | | | | | | | | | | | | | | | | | Some non soc-camera drivers, e.g. em28xx, use subdevice drivers, originally written for soc-camera, which use soc_camera_power_on() and soc_camera_power_off() helpers to implement their .s_power() methods. Those helpers in turn can enable and disable a clock, if it is supplied to them as a parameter. This works well when camera host drivers balance their calls to subdevices' .s_power() methods. However, some such drivers fail to do that, which leads to unbalanced calls to v4l2_clk_enable() / v4l2_clk_disable(), which then in turn produce kernel warnings. Such behaviour is wrong and should be fixed, however, sometimes it is difficult, because some of those drivers are rather old and use lots of subdevices, which all should be tested after such a fix. To support such drivers this patch adds a work-around, allowing host drivers or platforms to set a flag, in which case soc-camera helpers will only enable the clock, if it is disabled, and disable it only once on the first call to .s_power(0).

| | | | | | | | | | | To obtain a clock reference consumers supply their device object to the V4L2 clock framework. The latter then uses the consumer device name to find a matching clock.

* [media] s5p-mfc: call wake_up_dev if in suspend modePrathyush K2013-10-281-4/+6
| | | | | | | | | | | | | | | | | | | If a frame is still decoding when system enters suspend mode, we wait on the device queue for a interrupt condition. This sometimes leads to a timeout because the device queue might not be woken up everytime. Usually, the context queue gets woken up when that context's frame gets decoded. This patch adds a condition to wake up the device queue along with the context queue when the system is in suspend mode. Since the device queue is now woken up, we don't have to check the context's int_cond flag while waiting. Also, we can skip calling try_run after waking up the device queue to ensure that we don't have to wait for more than one frame to be processed.

| | | | | | | | | | | | | | | | | | | | | | | When the current context is running, 1] If release() or streamoff() is called on the current context, it waits until the job is aborted or finished. 2] If the job is finished, driver will call the v4l2_m2m_job_finish(). 3] If the job is aborted inside device_run callback, then driver has to inform the v4l2 mem2mem framework about the same by calling v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR. The current code doesn't call v4l2_m2m_job_finish() in the case, where the job is aborted from the device_run callback. This scenerio is producing a hang as the other queued contexts are not getting scheduled. By adding the ABORT state, driver can understand the current job is aborted and not finished. By checking this flag, driver can call v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR.

| | | | | | | | | | v4l2_m2m_streamoff drops the list of ready buffers but failed to reset the num_rdy counter to zero.

* [media] v4l: ti-vpe: Add de-interlacer support in VPEArchit Taneja2013-10-281-34/+358
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the de-interlacer block in VPE. For de-interlacer to work, we need to enable 2 more sets of VPE input ports which fetch data from the 'last' and 'last to last' fields of the interlaced video. Apart from that, we need to enable the Motion vector output and input ports, and also allocate DMA buffers for them. We need to make sure that two most recent fields in the source queue are available and in the 'READY' state. Once a mem2mem context gets access to the VPE HW(in device_run), it extracts the addresses of the 3 buffers, and provides it to the data descriptors for the 3 sets of input ports((LUMA1, CHROMA1), (LUMA2, CHROMA2), and (LUMA3, CHROMA3)) respectively for the 3 consecutive fields. The motion vector and output port descriptors are configured and the list is submitted to VPDMA. Once the transaction is done, the v4l2 buffer corresponding to the oldest field(the 3rd one) is changed to the state 'DONE', and the buffers corresponding to 1st and 2nd fields become the 2nd and 3rd field for the next de-interlace operation. This way, for each deinterlace operation, we have the 3 most recent fields. After each transaction, we also swap the motion vector buffers, the new input motion vector buffer contains the resultant motion information of all the previous frames, and the new output motion vector buffer will be used to hold the updated motion vector to capture the motion changes in the next field. The motion vector buffers are allocated using the DMA allocation API. The de-interlacer is removed from bypass mode, it requires some extra default configurations which are now added. The chrominance upsampler coefficients are added for interlaced frames. Some VPDMA parameters like frame start event and line mode are configured for the 2 extra sets of input ports.

* [media] v4l: ti-vpe: Add VPE mem to mem driverArchit Taneja2013-10-286-0/+2298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VPE is a block which consists of a single memory to memory path which can perform chrominance up/down sampling, de-interlacing, scaling, and color space conversion of raster or tiled YUV420 coplanar, YUV422 coplanar or YUV422 interleaved video formats. We create a mem2mem driver based primarily on the mem2mem-testdev example. The de-interlacer, scaler and color space converter are all bypassed for now to keep the driver simple. Chroma up/down sampler blocks are implemented, so conversion beteen different YUV formats is possible. Each mem2mem context allocates a buffer for VPE MMR values which it will use when it gets access to the VPE HW via the mem2mem queue, it also allocates a VPDMA descriptor list to which configuration and data descriptors are added. Based on the information received via v4l2 ioctls for the source and destination queues, the driver configures the values for the MMRs, and stores them in the buffer. There are also some VPDMA parameters like frame start and line mode which needs to be configured, these are configured by direct register writes via the VPDMA helper functions. The driver's device_run() mem2mem op will add each descriptor based on how the source and destination queues are set up for the given ctx, once the list is prepared, it's submitted to VPDMA, these descriptors when parsed by VPDMA will upload MMR registers, start DMA of video buffers on the various input and output clients/ports. When the list is parsed completely(and the DMAs on all the output ports done), an interrupt is generated which we use to notify that the source and destination buffers are done. The rest of the driver is quite similar to other mem2mem drivers, we use the multiplane v4l2 ioctls as the HW support coplanar formats.
