| * | [media] r820t: Allow disabling IMR callibrationMauro Carvalho Chehab2013-04-161-4/+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 Chehab2013-04-161-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code seems to calibrate I/Q phase and gain during the device initialization.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The rtl-sdr library, from where this driver was initially based, doesn't use half PLL clock, but this is used on the Realtek Kernel driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tuner works with 2 modes: automatic gain mode and manual gain mode. Put it into automatic mode, as we currently don't have any API for manual gain adjustment. The logic to allow setting the manual mode is there, as it is just a few extra code.

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.
