2013-12-11[media] v4l: vsp1: Supply frames to the DU continuouslyLaurent Pinchart
When operating in DU output mode (deep pipeline to the DU through the LIF), the VSP1 needs to constantly supply frames to the display.

2013-12-11[media] v4l: omap4iss: Cancel streaming when a fatal error occursLaurent Pinchart
When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued. Implement this behaviour with a new omap4iss_pipeline_cancel_stream() function that can be used by submodules to cancel streaming.

2013-12-11[media] v4l: omap4iss: csi2: Replace manual if statement with a subclk fieldLaurent Pinchart
Instead of manually checking whether the CSI2 module is CSI2a or CSI2b in order to select the right subclock to enable/disable, add a subclk field to the iss_csi2 structure, initialize it with the corresponding subclock value and use it at runtime.

2013-12-11[media] v4l: omap4iss: Reset the ISS when the pipeline can't be stoppedLaurent Pinchart
When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISS. However, as other users can be using a different pipeline with other modules, the ISS can't be reset synchronously with the error detection. Keep track of modules that have failed to stop, and reset the ISS accordingly when the last user releases the last reference to the ISS. Refuse to start streaming on a pipeline that contains a crashed module, as the hardware wouldn't work anyway. Modify the omap4iss_pipeline_set_stream() function to record the new ISS pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

2013-12-11[media] v4l: omap4iss: Enable/disabling the ISP interrupts globallyLaurent Pinchart
ISP interrupts are enabled/disabled when starting/stopping the IPIPEIF or resizer. This doesn't permit using the two modules in separate pipelines. Fix it by enabling/disabling the ISP interrupts at the same time as the ISS interrupts, in the ISS device get/put operations.

2013-12-11[media] v4l: omap4iss: resizer: Stop the whole resizer to avoid FIFO overflowsLaurent Pinchart
When stopping the resizer due to a buffer underrun, disabling RZA only produces input FIFO overflows, most probably when the next frame is received.

2013-12-11[media] v4l: omap4iss: isif: Ignore VD0 interrupts when no buffer is availableLaurent Pinchart
The ISIF generates VD0 interrupts even when writes are disabled. Disabling the ISIF when no buffer is available is thus not be enough, we need to handle the situation explicitly.

2013-12-10[media] v4l: ti-vpe: make sure VPDMA line stride constraints are metArchit Taneja
When VPDMA fetches or writes to an image buffer, the line stride must be a multiple of 16 bytes. If it isn't, VPDMA HW will write/fetch until the next 16 byte boundry. This causes VPE to work incorrectly for source or destination widths which don't satisfy the above alignment requirement. In order to prevent this, we now make sure that when we set pix format for the input and output buffers, the VPE source and destination image line strides are 16 byte aligned. Also, the motion vector buffers for the de-interlacer are allocated in such a way that it ensures the same alignment.

2013-12-10[media] v4l: ti-vpe: Fix the data_type value for UYVY VPDMA formatArchit Taneja
The data_type value to be programmed in the data descriptors to fetch/write a UYVY buffer was not mentioned correctly in the older DRA7x documentation. This caused VPE to fail with UYVY color formats. Update the data_type value to fix functionality when UYVY format is used.

2013-12-10[media] em28xx: add support for the SpeedLink Vicious And Devine Laplace webcamsFrank Schaefer
The SpeedLink Vicious And Devine Laplace webcam is using an EM2765 bridge and an OV2640 sensor. It has a built-in microphone (USB standard device class) and provides 3 buttons (snapshot, illumination, mute) and 2 LEDs (capturing/mute and illumination/flash). It is also equipped with an eeprom. The device is available in two colors: white (1ae7:9003) and black (1ae7:9004). For further details see http://linuxtv.org/wiki/index.php/VAD_Laplace. Please note the following limitations that need to be addressed later: - resolution limited to 640x480 (sensor supports 1600x1200) - picture quality needs to be improved - AV-mute button doesn't work yet Signed-off-by: Frank Schäfer <fschaefer.oss@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2013-12-10[media] em28xx: add support for illumination button and LEDFrank Schaefer

2013-12-10[media] em28xx: add debouncing mechanism for GPI-connected buttonsFrank Schaefer
So far, the driver only supports a snapshot button which is assigned to register 0x0c bit 5. This special port has a built-in debouncing mechanism. For buttons connected to ordinary GPI ports, this patch implements a software debouncing mechanism.

2013-12-10[media] em28xx: extend the support for device buttonsFrank Schaefer
The current code supports only a single snapshot button assigned to register 0x0c bit 5. But devices may be equipped with multiple buttons with different functionalities and they can also be assigned to the various GPI-ports. Extend the em28xx-input code to handle multiple buttons assigned to different GPI-ports / register addresses and bits. Also make easier to extend the code with further button types.
