The bttv card database structure had a "tuner" field that was the input number of the tuner input or UNSET for no tuner. However, the only values it could ever be are 0 and UNSET. Having a tuner on an input other than 0 didn't work and was never used. There is also a "tuner_type" field that can be set to TUNER_ABSENT to indicate no tuner, which makes "tuner = UNSET" redundant. In many cases, tuner_type was set to UNSET when there was no tuner, which isn't quite correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet known. So, I changed cards where "tuner == UNSET" to always have tuner_type of TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it. I have the card setup code set the card's tuner_type (not the card type's tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the setup code. Various places that check if the card has a tuner will now look for this instead of checking the card type's "tuner" field. Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C client call instead of after issuing it. Overall, on ia32 this decreases compiled code size by about 24 bytes and reduces the data size by 640 bytes. Signed-off-by:

The code to set the norm for the TDA9880 analog demod was comparing btv->norm, an index into the bttv driver's norm array, to V4L2_STD_NTSC, which is a bit flag that's part of the V4L2 API. This doesn't work of course and results in the PAL path always being taken. What's more, it modified the bttv_tvcards[] entries for cards using the TDA9880. This is wrong because changing the norm on one card will also affect other cards of the same type. Writing to bttv_tvcards is also bad because it should be read-only or even devinitdata. Changing the norm would also cause the audio to become unmuted. Have the code get called for both norm setting and audio input setting (which where the gpios are set) to avoid needed to modify bttv_tvcards. Signed-off-by:

The norm value in the driver is an index into an array and the the driver doesn't allow it to be negative or otherwise invalid. It should be unsigned but wasn't in all places. Fix some structs and functions to have the norm be unsigned. Get rid of useless checks for "< 0". Most of the driver code can't handle a norm value that's out of range, so change some ">= BTTV_TVNORMS" checks to BUG_ON(). There's no point in silently ignoring invalid driver state just to crash because of it later. Reported-by:

The cx2341x_mpeg_ctrls array must be ordered by control ID. I know that this is bad design, but for now I will just fix this bug and revisit it when all drivers have moved to v4l2_device/v4l2_subdev, since that will allow me to do greatly improve control handling. Signed-off-by:

Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion. It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow. Signed-off-by:

For i2c normal work, we need to slow down the bus speed. However, the slow down breaks the eeprom firmware load. So, use normal speed for eeprom booting and then restore the i2c speed after that. It should also be noticed that no other I2C transfer should be in course while booting from eeprom, otherwise, tda10046 goes into an instable state. So, proper locking are needed at the i2c bus master. Tested with saa7134 MSI TV @nyware A/D board, that comes with an eeprom with firmware version 29. Signed-off-by: -

KBL is not needed on saa7134, so, let's remove it. However, we should take some care to avoid opening the module while initializing it. This issue exists with newer udev's that opens a device as soon as the driver is registered. So, a proper lock is needed on open. Signed-off-by: -

Some saa7134 devices require to open an i2c gate before tuning. This patch fix the initialization for those devices. The nxt200x_gate_ctrl() logic were returned back to the old place, since we don't know how to close the gate. A future pacth could revert that change and provide the proper close gate control, to avoid keeping it open forever. Signed-off-by: -

On certain devices, before opening a tuner, we need to open the tuner gate via i2c. This patch just moves the tuner probing code to the same place where such i2c commands are handled, to make easier to fix this trouble on later patches. Signed-off-by: -

Mauro Carvalho Chehab authored
The gate control logic is broken: several routines just keep it open; other rotines close it properly; there are even other routines that assumes that it is open without really checking or opening it. Instead of having to manually handle the gate control and having such troubles, let a sub-routine take care of the gate, opening it before i2c_transfer and closing it after that. This avoids leaving the gate into a random state. Cc: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: -

Modified mxb to load the i2c modules through v4l2_subdev. So no more probing. Modified tea6415c and tea6420 to use the standard routing ops to do the routing, rather than using private commands. Dropped the private commands from tda9840 (they were never used except during initialization of the module). Added saa7146 support for VIDIOC_DBG_G_CHIP_IDENT. Converted saa5246a and saa5249 to v4l2_subdev. Signed-off-by:
