Length of H.264 headers is variable and thus it might not be aligned for the coda to append the encoded frame. This causes the first frame to overwrite part of the H.264 PPS. In order to solve that, a filler NAL must be added between the headers and the first frame to preserve alignment.

Since rc_unregister_device() frees its argument there's no need to subsequently call rc_free_device() on the same variable - in fact it's a double free bug. Easily fixed by just removing the rc_free_device() call. Signed-off-by:

At the 'err_request_irq' label, rc_unregister_device(rcdev) frees its argument. So when we fall through to the 'err_gpio_request' label further down and call rc_free_device(rcdev) then that's a double free. Fix that by moving 'rcdev = NULL' from after the call to rc_free_device() to after rc_unregister_device(). That fixes the problem since rc_free_device() just does nothing if passed NULL and there's no further use of 'rcdev' after the call to rc_free_device() so it's not needed there. Signed-off-by:

We have assigned error code to 'ret' if crop->type is not V4L2_BUF_TYPE_VIDEO_OUTPUT, but never use it. We'd better return the error code on this error. Signed-off-by:

In case of error, the function vb2_dma_contig_init_ctx() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by:

This patch allows enabling building of VPBE display driver for DM365 and DM355. This also removes unnecessary entry VIDEO_DM644X_VPBE in Kconfig, which could have been done with single entry, and appropriate changes in Makefile for building. Signed-off-by:

The vpbe driver can handle different platforms DM644X, DM36X and DM355. To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform. Taking this approach will also make the DT transition easier. Signed-off-by:

Add the video resizer driver with the v4l2 media controller framework which takes care of resizing the video frames with both up-scaling downscaling facility. The driver supports both continuous and single shot operations.The driver supports resizer as a subdevice and a media entity. It has support for 2 resizers - resizerA and resizerB. Signed-off-by:

Add the IPIPE subdevice to the DM365 vpfe driver. The IPIPE is the major sub IP in the DM365 capture VPFE hardware and implements black clamping, color space conversion, edge enhancements etc. the block is exposed as a subdevice and implements media controller based setup and a private IOCTL for fine grain control.

add support for ISIF as a subdevice for dm365 vpfe capture driver. ISIF is responsible for capturing video data both in raw bayer format on sync seperate signals and YUV through BT656/1120 interfaces. ISIF is exposed as a subdev for the vpfe driver and allows users to use the driver through standard media controller interface. Signed-off-by:

Add a generic video driver functionality to be used by all the vpfe drivers for davinci SoCs. The functionality includes all the standard v4l2 interfaces including streaming. The video node interface can be used both as an input and output node for both continuous and single shot modes. Also supports dv_presets to include HD modes, wth support for both user pointer IO and mmap. The buffering mechanism is based on videobuf2 interface. Signed-off-by:

Add the vpfe capture driver which implements media controller interface. The driver supports the DM365 sub ip units for capture namely - ISIF, IPIPE, IPIPEIF, Resizer. This file represents the main driver which does isr registration, v4l2 device registration, media registration and platform driver registrations. It calls the appropriate subdevs from here to create subdevices and media entities. Signed-off-by:

We must wait for the previous i2c write to complete before starting a new one. Sofar we were getting away with this, but it seems that some parts of the usb-subsystem has been sped up making us go to fast :) This fixes streaming on sn9c103 based cams not working with an "i2c_w error" error.

The stk-webcam module is inserted upside-down in some webcams, so we need to de hflip and vflip by default on some models. Note that this patch inverts the value of the controls as reported by the control API in this case so that for the user they still make sense (iow not doing any flipping from the ctrl API pov results in an upright image).

Add second source media pad for the FIFO data output to FIMC-IS and implement subdev s_stream op for configurations where FIMC-LITE is used as a glue logic between FIMC-IS and MIPI-CSIS or an image sensor. The second source media pad will be linked to the FIMC-LITE video node. For proper configuration the attached image sensor/video encoder properties are needed, like video bus type, signal polarities, etc. For this purpose there is a small routine added that walks the pipeline and returns the sensor subdev.
