* [media] media: v4l2-ctrls: Fix 64bit support in get_ctrl()Benoit Parrot2015-10-011-3/+3
| | | | | | | | | | | | | | | | | | | When trying to use v4l2_ctrl_g_ctrl_int64() to retrieve a V4L2_CTRL_TYPE_INTEGER64 type value the internal helper function get_ctrl() would prematurely exit because for this control type the 'is_int' flag is not set. This would result in v4l2_ctrl_g_ctrl_int64 always returning 0. Also v4l2_ctrl_g_ctrl_int64() is reading and returning the 32bit value member instead of the 64bit version, so fixing that as well. This patch extends the condition check to allow the V4L2_CTRL_TYPE_INTEGER64 type to continue processing instead of exiting.

* [media] s5p-jpeg: add support for 5433Andrzej Pietrasiewicz2015-10-016-66/+522
| | | | | | | | | | | | | | | | | | | | | | | | | JPEG IP found in Exynos5433 is similar to what is in Exynos4, but there are some subtle differences which this patch takes into account. The most important difference is in what is processed by the JPEG IP and what has to be provided to it. In case of 5433 the IP does not parse Huffman and quantisation tables, so this has to be performed with the CPU and the majority of the code in this patch does that. A small but important difference is in what address is passed to the JPEG IP. In case of 5433 it is the SOS (start of scan) position, which is natural, because the headers must be parsed elsewhere. There is also a difference in how the hardware is put to work in device_run. Data structures are extended as appropriate to accommodate the above changes.

* [media] s5p-jpeg: generalize clocks handlingMarek Szyprowski2015-10-012-39/+37
| | | | | | | | | | | | | | | | | | | | | Allow jpeg codec variants declare clocks they need. Before this patch is applied jpeg-core gets jpeg->sclk "speculatively": if it is not there, we assume no problem. This patch eliminates this by explicitly declaring what clocks are needed for each variant. This is a preparation for adding Exynos 5433 variant support, which needs 4 clocks of names not compatible with any previous version of jpeg hw module.

* [media] s5c73m3: Export OF module alias informationJavier Martinez Canillas2015-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The SPI core always reports the MODALIAS uevent as "spi:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: SPI id table or OF match table). So drivers needs to export the SPI id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and SPI id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same SPI device name for example. To avoid the above, the SPI core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes.

* [media] use v4l2_get_timestamp where possibleArnd Bergmann2015-10-018-28/+10
| | | | | | | | | | | | | | | | | This is a preparation for a change to the type of v4l2 timestamps. v4l2_get_timestamp() is a helper function that reads the monotonic time and stores it into a 'struct timeval'. Multiple drivers implement the same thing themselves for historic reasons. Changing them all to use v4l2_get_timestamp() is more consistent and reduces the amount of code duplication, and most importantly simplifies the following changes.

This is both an incorrect API use, and a bad idea because of the y2038 problem and the fact that the wall clock time is not reliable for timestamps across suspend or settimeofday(). This changes the driver to use the normal v4l2_get_timestamp() function like all other drivers.

* [media] atmel-isi: add sanity check for supported formats in try/set_fmt()Josh Wu2015-09-251-8/+29
| | | | | | | | | | After adding the format check in try_fmt()/set_fmt(), we don't need any format check in configure_geometry(). So make configure_geometry() as void type.

* [media] atmel-isi: move configure_geometry() to start_streaming()Josh Wu2015-09-251-12/+5
| | | | | | | | | | | | | As in set_fmt() function we only need to know which format is been set, we don't need to access the ISI hardware in this moment. So move the configure_geometry(), which access the ISI hardware, to start_streaming() will make code more consistent and simpler.

* [media] atmel-isi: setup the ISI_CFG2 register directlyJosh Wu2015-09-252-13/+9
| | | | | | | | | | | | | | | | In the function configure_geometry(), we will setup the ISI CFG2 according to the sensor output format. It make no sense to just read back the CFG2 register and just set part of it. So just set up this register directly makes things simpler. Currently only support YUV format from camera sensor.

* [media] atmel-isi: increase timeout to disable/enable isiJosh Wu2015-09-251-1/+1
| | | | | | | | | If ISI is working on a 1024x768 or higher resolution, it needs longer time to disable ISI. So this patch will increase timeout to 500ms.

* [media] rcar_vin: call g_std() instead of querystd()Sergei Shtylyov2015-09-251-2/+2
| | | | | | | | | | | | Hans Verkuil says: "The only place querystd can be called is in the QUERYSTD ioctl, all other ioctls should use the last set standard." So call the g_std() subdevice method instead of querystd() in the driver's set_fmt() method.
