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:

Enable the standby mode optimization to disable the tda18271 slave tuner output / loop thru options when in low power mode on the slave tuner, only. The master tuner must always leave slave tuner output / loop thru enabled. 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.

gspca-w9968cf: Don't add an extra packet to the buffer after the EOF, this makes the frame data size bigger then it should be which makes gstreamer discard it. This patch also fixes an unrelated compiler warning. Signed-off-by:

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:

Hans de Goede authored
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.

Support for settings the input standard of the ADV7180. When the input standard is set there is no use to ask the chip for standard, therefore it is cached in the driver. Signed-off-by:

This patch adds support to the ADV7180 driver to check the input status. Since the status is held in the same register as the input standard a small restructuring of the code is done to reuse the code for reading the register Signed-off-by:

V4L/DVB (13168): Add support for Asus Europa Hybrid DVB-T card (SAA7134 SubVendor ID: 0x1043 Device ID: 0x4847) Adds the device IDs and driver linking to allow the Asus Europa DVB-T card to operate with these drivers. The device has a SAA7134 chipset with a TD1316 Hybrid Tuner. All inputs work on the card including switching between DVB-T and Analogue TV, there is also no IR with this card.

The definition of tvaudio_tuner_ops initializes the s_tuner field twice. It appears that the second case should initialize the g_tuner field. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by:

When the image size (bytesperline*height) is not multiple of PAGE_SIZE, v4l2 rounded the required buffer size to be multiple of PAGE_SIZE. This prevented user space to store images directly into userptr buffers which were not multiple of PAGE_SIZE. This constraint is removed. The start address is still assumed to be required page-aligned, ie., when v4l2 allocates mmap buffers, the offset between different buffers is page-aligned. Signed-off-by:

DVBS2API introduced two new ioctls that allows changing/getting details about newer video standards like DVB-S2 and ISDB-T. There are lots of thing to do in this chapter, but, for now, just add a session there, in order to allow make to not complain about undefined symbol. With this patch, all ioctls at the frontend.h API were somehow documented. Signed-off-by:
