stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock". Signed-off-by:

It is mostly copy/paste of the 520e code with setting GPIO7 removed (no LED light). I've worked on just released vanilla linux-3.3.0 kernel, so there may be 1/2 lines offset to the internal working source, but most of the code should apply cleanly. I was able to get the DVB-C working (tuned and watched TV). Haven't tested DVB-T (no signal atm). Special thanks to everybody who worked on the code and to Antti Palosaari and Devin Heitmueller who provided essential support on irc. Hardware is based of: Empia EM2884 Micronas DRX 3926K NXP TDA18271HDC2 AVF4910 (not used atm) Signed-off-by:

Hardware is based of: Empia EM2884 Micronas DRX 3926K NXP TDA18271HDC2 ... + analog parts. Analog is not supported currently. Only DVB-T and DVB-C. There seems to be still problems for locking DVB-C channels which have strong signal. Attenuator helps. I think it is demodulator IF/RF AGC issue. Lets fix it later. Patches are welcome.

I found one more place where -EINVAL is used instead of -ENOTTY: Note that drivers/media/dvb/dvb-core/dvbdev.c has the same code, but as far as I can tell DVB is still using -EINVAL for unknown ioctls so I didn't change that. Signed-off-by:

The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner instead of a tda18271c1 tuner as used in revision D1E9. To account for this, we must hardcode the frontend configuration to use the same IF frequency configuration for both revisions of the device. 6MHz DVB-T is unaffected by this issue, as the recommended IF Frequency configuration for 6MHz DVB-T is the same on both c1 and c2 revisions of the tda18271 tuner.

We still need to power up the controller to avoid unsightly self-immolation should something try to access its registers, but the sensor can stay powered down unless the camera was actually operating at suspend time. This gets rid of the camera LED flash on resume, fixing OLPC bug #11644. Signed-off-by:

There is only one frame known to the DMA engine in scatter/gather mode, but it still tells us that any or all of frames 1-3 are done at each completion interrupt. Avoid the creation of junk frames by being sure to only "complete" one on each interrupt. Signed-off-by:

I had learned through hard experience that dinking around with the DMA descriptors while the C1_DESC_ENA enable bit was set is a recipe for all kinds of truly malicious behavior on the hardware's part, regardless of whether the DMA engine is actually operating at the time. That notwithstanding, the driver did so dink, resulting in "green frame" captures and the death of the system in random, spectacular ways. Move the tweaking of C1_DESC_ENA to the same function that sets the descriptor so we know that we'll never try to set a descriptor while that bit is set. Signed-off-by:

Experience shows that, on the Armada platform, it can take as much as 120ms for the DMA engine to actually shut down after it has been told to. So a 40ms timeout is not adequate; use 150ms instead. Also make sure we don't leave the DMA_ACTIVE flag set once things are down. Signed-off-by:

The marvell cam driver retained just enough of the owner-tracking logic from cafe_ccic to be broken; it could, conceivably, cause the driver to release DMA memory while the controller is still active. Simply remove the remaining pieces and ensure that the controller is stopped before we free things. Signed-off-by:

The controller stop/restart logic could possibly restart DMA after the driver things things have stopped, with suitably ugly results. Make sure that we only restart the hardware if we're supposed to be streaming. Signed-off-by:

soc_camera_power_on() calls client's .s_power(1) method, which can try to access the client hardware. This, however, is typically only possible, after calling host's .add() method, because that's where the host driver usually turns the master clock on. Signed-off-by:

This changes rc_core to not load the IR decoders at load time, postponing it to load only if a RC_DRIVER_IR_RAW device is registered via rc_register_device. We use a static boolean variable, to ensure decoders modules are only loaded once. Tested with rc-loopback device only. Signed-off-by:

Remove incorrect SEC_MINI_B settings-TODO complete this section. Correct break and remove return -EINVAL within set tone. It appears there is a bug that occasionally something other than ON/OFF is sent stalling the driver. Just continue and write back registers. Set register b2 in setup. This is the set voltage pin which isn't used in lmedm04 driver but it is always set to 0x1. Correct the if statements in set_tuner_rf. Signed-off-by:

The i2c failures were caused by enabling both i2c gates at the same time while putting the tuners asleep. This patch removes the init() and sleep() callbacks from the tuner, to prevent frontend.c from calling i2c_gate_ctrl tuner init / sleep i2c_gate_ctrl without holding the lock. tuner init() and sleep() are instead called in frontend init() and sleep().

struct dvb_usb_device *d can never be NULL so don't waste time checking for this. Rationale: the urb's context is set when usb_fill_bulk_urb() is called in dib0700_rc_setup(), and never changes after that. d is dereferenced unconditionally in dib0700_rc_setup() so it can't be NULL or the driver would crash right away.

The au8522 driver programs the tuner after programming the demodulator, but the tuner should be programmed first. This patch fixes this behavior. EDIT: Apparantly Devin created a similar patch some time ago, but hasn't submitted it for merge. I never saw his patch, but I thank him anyhow for his efforts. In addition, Devin pointed out a flaw in my patch: This newly generated patch takes Devin's comments into account. Thanks-to: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by:
