| * | | [media] r820t: fix PLL calculusMauro Carvalho Chehab2013-04-171-17/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few errors at the PLL calculus, causing the device to use wrong values. While here, change the calculus to use 32 bits, as there's no need for 64 bits there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Antti Palosaari <crope@iki.fi>

| * | | [media] r820t: Allow disabling IMR callibrationMauro Carvalho Chehab2013-04-171-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtl-sdr library disabled IMR callibration. While I'm not sure yet why, it could be a good idea to add a modprobe parameter here, to allow to also disable it. There are two rationale behind it: - It helps to compare USB dumps between rtl-sdr and the Kernel module; - If rtl-sdr disabled it, perhaps there's a good reason (e. g. it might not be actually working, or it might be causing some trouble). For both cases, it seems useful to add a modprobe parameter to allow testing the device with both configurations.

| * | | [media] r820t: add a commented code for GPIOMauro Carvalho Chehab2013-04-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the code to set the GPIO for this tuner. This code is currently unused, so it is kept there only for completeness. With this patch there are just two things that got left from the original driver: - At standby, there's another mode, not used by rtl2832u. Not sure if it might be needed in the future, but I suspect it is not used at all; - There is a "fast tune" mode. As nor DVB or V4L API supports it, it seems an overkill to implement it.

I couldn't find the original tree. However, the original driver look awkward on my eyes. So, I decided to write a new version from it from the scratch, while trying to reproduce everything found there. TODO: - After locking, the original driver seems to have some routines to improve reception. This was not implemented here yet. - RF Gain set/get is not implemented.

* | | | [media] exynos4-is: Fix driver name reported in vidioc_querycapSylwester Nawrocki2013-04-254-16/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally struct v4l2_capability driver and card name was filled with name of the platform device. After switching to the device tree the device names have changed and now are 4 different driver names reported, depending on the video device opened. So instead of e.g. "exynos4-fimc" there is now one of: 11800000.fimc, 11810000.fimc, 11820000.fimc, 11830000.fimc. Fix this by using dev->driver_name, rather than platform device name. A common vidioc_querycap function is created for both M2M and capture video node. This fixes any breakage at user space should any application/library rely on the driver's name.
