2018-05-10media: dvbsky: use just one mutex for serializing device R/W opsMauro Carvalho Chehab1-10/+6
Right now, there are two mutexes serializing r/w ops: one "generic" and another one specifically for stream on/off. Clean it a little bit, getting rid of one of the mutexes. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2018-05-09media: omap3isp: support 64-bit version of omap3isp_stat_dataArnd Bergmann5-3/+30
C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.

This issue was reported by a user who downloaded a corrupt saa7164 firmware, then went looking for a valid xc5000 firmware to fix the error displayed...but the device in question has no xc5000, thus after much effort, the wild goose chase eventually led to a support call. The xc5000 has nothing to do with saa7164 (as far as I can tell), so replace the string with saa7164 as well as give a meaningful hint on the firmware mismatch.

2018-05-09media: renesas-ceu: Set mbus_fmt on subdev operationsJacopo Mondi1-5/+15
The renesas-ceu driver intializes the desired mbus_format at 'complete' time, inspecting the supported subdevice ones, and tuning some parameters to produce the requested memory format from what the sensor can produce. Although, the initially selected mbus_format was not provided to the subdevice during set_fmt and try_fmt operations, providing instead a '0' mbus format code. As long as the sensor defaults to a compatible mbus_format when an invalid code as '0' is provided, capture operations work correctly. If the subdevice defaults to an unsupported format (eg. some RGB permutations) capture does not work properly due to a mismatch on the expected and received image format on the wire. Fix that by re-using the initially selected mbus_format code during set_fmt and try_fmt subdevice operation calls. Tested by printing out the format selection procedure with ov7670 sensor.

2018-05-09media: videobuf-dma-sg: Fix dma_{sync,unmap}_sg() callsRobin Murphy1-2/+2
This reverts commit fc7f8fd42c2b934ac348995e0c530c917fc277d5. Whilst the rationale for the above commit was in general correct, i.e. that users *consuming* the DMA addresses should rely on sglen rather than num_pages, it has always been the case that the DMA API itself still requires that dma_{sync,unmap}_sg() are called with the original number of entries as passed to dma_map_sg(), not the number of mapped entries it returned. Thus the particular changes made in that patch were erroneous. At worst this might lead to data loss at the tail end of mapped buffers on non-coherent hardware, while at best it's an example of incorrect DMA API usage which has proven to mislead readers.

The VIN Gen3 hardware don't have Line Post-Clip capabilities as VIN Gen2 hardware have. To protect against writing outside the capture window enable field toggle after a set number of lines have been captured. Capturing outside the allocated capture buffer where observed on R-Car Gen3 Salvator-XS H3 from the CVBS input if the standard is misconfigured. That is if a PAL source is connected to the system but the adv748x standard is set to NTSC. In this case the format reported by the adv748x is 720x480 and that is what is used for the media pipeline. The PAL source generates frames in the format of 720x576 and the field is not toggled until the VSYNC is detected and at that time data have already been written outside the allocated capture buffer. With this change the capture in the situation described above results in garbage frames but that is far better then writing outside the capture buffer.

2018-05-05media: ngene: cleanup superfluous I2C adapter evaluationDaniel Scheller1-13/+0
Commit ee93340e98bc ("media: ngene: deduplicate I2C adapter evaluation") added a helper to evaluate the I2C adapter to be used for demod/tuner attachment based on the given ngene_channel, and that helper is used in many attach functions to initialise the i2c_adapter variable. However, for some reason in tuner_attach_stv6110() and demod_attach_stv0900(), the adapter evaluation wasn't removed as in all other functions. Fix (or finalize, even) the helper use by cleaning up the superfluous I2C adapter evaluation leftover in these two functions.

The value from a readl is being masked with ITE_REG_CIOCAN_MASK however this is not being used and cfg is being re-assigned. I believe the assignment operator should actually be instead the |= operator.
