2013-04-22[media] go7007: dubious one-bit signed bitfieldsDan Carpenter
Because they're signed, "is_video" and "is_audio" can be 0 and -1 instead of 0 and 1 as intended.

2013-04-22[media] cx88: Fix unsafe locking in suspend-resumeAlexey Khoroshilov
Legacy PCI suspend-resume handlers are called with interrupts enabled. But cx8800_suspend/cx8800_resume and cx8802_suspend_common/cx8802_resume_common use spin_lock/spin_unlock functions to acquire dev->slock, while the same lock is acquired in the corresponding irq-handlers: cx8800_irq and cx8802_irq. That means a deadlock is possible if an interrupt happens while suspend or resume owns the lock. The patch replaces spin_lock/spin_unlock with spin_lock_irqsave/spin_unlock_irqrestore.

2013-04-16[media] r820t: Allow disabling IMR callibrationMauro Carvalho Chehab
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 Chehab
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 Chehab

2013-04-16[media] r820t: proper initialize the PLL registerMauro Carvalho Chehab

2013-04-16[media] r820t: Set gain mode to autoMauro Carvalho Chehab
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 Chehab
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 Chehab
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.
