It used to be that the only real detectable reason for the driver to fail during initialization would be that if the hardware is simply jammed. However with the advent of the sub-device mechanism in V4L it is possible now to detect if a sub-device module fails to load successfully. The pvrusb2 driver does in fact react to this by also (correctly) failing, however the original diagnostic message "hardware is jammed" was still being reported. This misleads the user because in fact it might not actually be a hardware failure. This change adds logic to tell the difference and then report a more appropriate message to the kernel log.

pvrusb2: Encoder failures are mostly recoverable by the driver. While it would sure be nice not to have the failure happen in the first place, this has been going on for years and I doubt that a real solution will ever present itself. I think that part's firmware is just slightly flakey and we have to deal with it. The driver does deal with it just fine, but the warning message going into the kernel log is probably a little more alarming than it should be. So try to soften up the warning somewhat.

consolidate common code used to determine if calibration on startup is needed Signed-off-by:
-
Michael Krufky authored
If rf_cal_on_startup is enabled in the structure passed into tda18271_attach, and the cal module option isn't disabled, then we should run the initialization and calibration procedures during the tda18271_attach function call, regardless of how many instances of the driver have been attached. If the device is already calibrated, the driver will detect that and will only calibrate again if necessary. Signed-off-by:

There is already an option for sending 16 byte chunks rather that writing 39 bytes all at once during the tuner's initialization. Some i2c buses can't send 16 bytes at once, so create an option for sending 8 byte chunks. Signed-off-by:

gspca: Don't resubmit error status URB's when suspending Signed-off-by:
-
Hans de Goede authored
The gscpa core was not resubmitting URB's when the URB status was an error, this means we will loose URB's (potentially all stopping the stream) in case of sporadic USB issues. I've seen this with an Aiptek stv0680 based PenCam connected through an USB 2.0 hub. Signed-off-by:

This patch adds a new subdriver to gspca supporting cams with the stv0680 bridge (replacing the old in kernel v4l1 driver). Many thanks to Hans Verkuil for providing me with one of the 2 cams used in testing this new sub driver. Signed-off-by:

gspca w9968cf: slight tweak to vstart and hstart to get rid of black borders in 640x480 mode. Signed-off-by:

Hans de Goede authored
gspca w9968cf: Add support for JPEG compression, this enables much higher framerates at 320x240 / 352x288 and also allows for 640x480 mode for cams which can do this. The w9968cf uses planar JPEG, which libv4l until now did not support, so this requires atleast version 0.6.3 of libv4l. And something important I forgot to mention in my earlier w9968cf commits: Many thanks to Hans Verkuil for giving me a w9968cf based cam, which has allowed me to develop the gspca w9968cf support.

Cache sensor regs to avoid unnecessary slow i2c reads / writes, this speeds up sd_start a bit with most bridges and a lot (from 5 seconds down to 0.3 seconds) with W996xCF cams, as this avoids very slow bit bang IO over USB i2c reads. Signed-off-by:

This patch adds support to gspca for the Winbond W9967CF and W9968CF camera's. This is mostly a port of the existing v4l1 driver to gspca (making it v4l2). But this also features fixes to the bitbanging i2c code (send a nack not an ack after reading the last byte of a transfer), which gets rid of the weird errors which were being seen there, and of the smbus_refresh() hack to get around these errors. Also the vstart settings have been tweaked to work with different frequency filter settings. Signed-off-by:

If the I2C device provides an interrupt it is registered and the standard is updated via interrupts rather than polling. Since I2C communication is needed, the interrupt handler fires off a work which will check the new standard, and store it in the internal structure. To handle mutual exclusion a mutex is introduced.
