2013-04-16[media] r820t: Don't divide the IF by twor820tMauro Carvalho Chehab1-0/+3
The original Win driver doesn't do; rtl-sdr also disabled that piece of the code. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Antti Palosaari <crope@iki.fi>
2013-04-16[media] r820t: disable auto gain/VGA settingMauro Carvalho Chehab1-5/+3
On field tests, the auto gain routine is not working, nor it is used by the original driver. Let's comment it for now. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Antti Palosaari <crope@iki.fi>
2013-04-16[media] rtl2832: Fix IF calculusMauro Carvalho Chehab1-0/+4

2013-04-16[media] r820t: fix PLL calculusMauro Carvalho Chehab1-17/+10
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>
2013-04-16[media] r820t: Don't put it in standby if not initialized yetMauro Carvalho Chehab1-0/+4

2013-04-16[media] r820t: Allow disabling IMR callibrationMauro Carvalho Chehab1-4/+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.

2013-04-16[media] r820t: add a commented code for GPIOMauro Carvalho Chehab1-0/+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.

2013-04-16[media] r820t: add IMR calibrate codeMauro Carvalho Chehab1-21/+681
This code seems to calibrate I/Q phase and gain during the device initialization. This is done only once, and it doesn't seem to be needed to happen after resuming. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Antti Palosaari <crope@iki.fi>
2013-04-16[media] r820t: proper initialize the PLL registerMauro Carvalho Chehab2-15/+31
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. So, also do the same here. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Antti Palosaari <crope@iki.fi>
2013-04-16[media] r820t: use usleep_range()Mauro Carvalho Chehab1-4/+4

2013-04-16[media] r820t: fix prefix of the r820t_read() functionMauro Carvalho Chehab1-8/+8

2013-04-16[media] r820t: Show the read data in the bit-reversed orderMauro Carvalho Chehab1-2/+3

2013-04-16[media] r820t: use the second table for 7MHzMauro Carvalho Chehab1-2/+10

2013-04-16[media] r820t: Set gain mode to autoMauro Carvalho Chehab1-0/+91
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. This way, if/when we latter add support for setting the gain mode, the code is already there.

2013-04-16[media] r820t: Add a tuner driver for Rafael Micro R820T silicon tunerMauro Carvalho Chehab4-0/+1549
This driver was written from scratch, based on an existing driver that it is part of rtl-sdr git tree, released under GPLv2: https://groups.google.com/forum/#!topic/ultra-cheap-sdr/Y3rBEOFtHug https://github.com/n1gp/gr-baz http://cgit.osmocom.org/rtl-sdr/plain/src/tuner_r820t.c (there are also other variants of it out there) >From what I understood from the threads, the original driver was converted to userspace from a Realtek tree. 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.

2013-04-16[media] it913x: rename its tuner driver to tuner_it913xMauro Carvalho Chehab5-4/+4
There are three drivers with *it913x name on it, and they all belong to the same device: a tuner, at it913x.c; a frontend: it913x-fe.c; a bridge: it913x.c, renamed to dvb_usb_it913x by the building system. This is confusing. Even more confusing are the two .c files with the same name under different directories, with different contents and different functions. So, prepend the tuner one. This also breaks the out-of-tree compilation system.
