2011-09-21[media] mt9t001: Aptina (Micron) MT9T001 3MP sensor driverLaurent Pinchart3-0/+843
The MT9T001 is a parallel 3MP sensor from Aptina (formerly Micron) controlled through I2C. The driver creates a V4L2 subdevice. It currently supports binning and cropping, and the gain, exposure, test pattern and black level controls.

2011-09-21[media] omap3isp: video: Avoid crashes when pipeline set stream operation failsLaurent Pinchart1-0/+8
If streaming can't be enabled on the pipeline, the DMA buffers queue is not emptied. If the buffers then get freed the queue will end up referencing free memory. This is usually not an issue, as the DMA queue will be reinitialized the next time streaming is enabled, before enabling the hardware. However, if the sensor connected at the pipeline input is free-running, the CCDC will start generating interrupts as soon as it gets powered up, before the streaming gets enabled on the hardware. This will make the CCDC interrupt handler access freed memory, causing a crash. Reinitialize the DMA buffers queue in isp_video_streamon() if the error path to make sure this situation won't happen.

2011-09-21[media] imon: don't parse scancodes until intf configuredJarod Wilson1-4/+6
The imon devices have either 1 or 2 usb interfaces on them, each wired up to its own urb callback. The interface 0 urb callback is wired up before the imon context's rc_dev pointer is filled in, which is necessary for imon 0xffdc device auto-detection to work properly, but we need to make sure we don't actually run the callback routines until we've entirely filled in the necessary bits for each given interface, lest we wind up oopsing. Technically, any imon device could have hit this, but the issue is exacerbated on the 0xffdc devices, which send a constant stream of interrupts, even when they have no valid key data.

2011-09-21[media] STV0288 frontend provide wider carrier search and DVB-S2 drop out. resendtvboxspy1-8/+21
The following patch provides wider carrier search. As with existing code search starts at MSB aligned. The boundary is widened to start at -9. In order to save time, if no carrier is detected at the start it advances to the next alignment until carrier is found. The stv0288 will detect a DVB-S2 carrier on all steps , a time out of 11 steps is introduced to drop out of the loop. In stv0288_set_symbol carrier and timing loops are restored to default values (inittab) before setting the symbol rate on each tune. A slight drift was noticed with full scan in the higher IF frequencies of each band. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-09-21[media] noon010pc30: Conversion to the media controller APISylwester Nawrocki2-69/+154
Replace g/s_mbus_fmt ops with the pad level get/set_fmt operations. Add media entity initialization and set subdev flags so the host driver creates a subdev device node for the driver. A mutex was added for serializing the subdev operations. When setting format is attempted during streaming an (EBUSY) error will be returned. After the device is powered up it will now remain in "power sleep" mode until s_stream(1) is called. The "power sleep" mode is used to suspend/resume frame generation at the sensor's output through s_stream op.

2011-09-21[media] v4l2-ctrls: implement new volatile autocluster schemeHans Verkuil1-8/+66
The problem tackled in this patch is how to handle volatile autoclusters correctly. A volatile autocluster is a cluster of related controls where one control is the control that toggles between manual and auto mode and the other controls are the values for the manual mode. For example autogain and gain, autoexposure and exposure, etc. If the hardware lets you read out the automatically calculated manual values while in automode, then those manual controls should be marked volatile. gain value as calculated by the autogain circuitry, then you would mark the gain control as volatile (i.e. continuously changing). The question in such use cases is what to do when switching from the auto mode to the manual mode. Should we switch to the last set manual values or should the volatile values be copied and used as the initial manual values. For example: suppose the mode is manual gain and gain is set to 5. Then autogain is turned on and the gain is set by the hardware to 2. Finally the user switches back to manual gain. What should the gain be? 2 or 5? After a long discussion the decisions was made to keep the last value as calculated by the auto mode (so 2 in the example above). The reason is that webcams that do such things will adapt themselves to the current light conditions and when you switch back to manual mode you expect that you keep the same picture. If you would switch back to old manual values, then that would give you a suddenly different picture, which is jarring for the user. Additionally, this would be difficult to implement in applications that store and restore the control values at application exit and start. If you want to keep the old manual values when you switch from auto to manual, then there would have to be a way for applications to get hold of those old values while in auto mode, but there isn't. So this patch will do all the heavy lifting in v4l2-ctrls.c: if you go from auto mode to manual mode and the manual controls are volatile, then g_volatile_ctrl will be called to get the current values for the manual controls before switching to manual mode.
