After the i2c subdev changes the ordering of initialization changed, causing a total loss of previous GPIO settings and a loss of DTV. The generic firmware loading routine has now changed to preserve GPIO values if the device is cx23885 based (safety) and I've moved the GPIO configuration from probe() into the cx23885 init func which is a little clearer and fixes the bug.

There is no point in defining I2C adapter IDs when no code is using them. As this field might go away in the future, stop using it when we don't need to. Signed-off-by:

Replace printing to magically sized temporary buffer with use of KERN_CONT for continual printing of eeprom registers dump. Since deb_info is defined as dprintk, which is conditionally defined to printk without additional parameters, meaning that deb_info is equivalent to direct printk (without adding KERN_ facility), we can use KERN_DEBUG and KERN_CONT in there, eliminating the need for sprintf into temporary buffer with not easily readable/magical size. Though it's strange, that deb_info definition uses printk without KERN_ facility and callers don't use it either. Signed-off-by:

Remove the subdev_s_std() method from the GPIO subdev. It appears it was used in the past to effect the switch back from radio mode to tuner mode, but it had a side effect that is improper and against the V4L2 spec, when you were not in radio mode. Whenever the video stanadrd was changed, the GPIO audio mux was set back to the tuner audio input, even if you were set to a Line In input. Thanks to Ravi A. for doing the troubleshooting to point me right to the problem. Reported-by:

At least one MT6227 model crashes when receiving a GET_DEF request on the video probe control. As the various models can't be told apart based on the descriptors, add a PROBE_DEF quirk to avoid sending the GET_DEF request and enable the quirk for all models. Signed-off-by:

. added code to print an error message when buffer is too small to hold frame data, that is better than just a hard crash. Tested using MAX_FRAME_SIZE = 50000, lots of error messages appeared in /var/log/messages but no crash. . removed line "f->type = V4L2_BUF_TYPE_VIDEO_CAPTURE;" in zr364xx_vidioc_try_fmt_vid_cap, it should not be there. . changes to improve performance (or at least not hurt it): removed some unneeded debug messages; added macro FULL_DEBUG to enable debug messages in performance critical places, this macro is disabled by default; removed "if (frm->lpvbits == NULL)..." in zr364xx_read_video_callback because after analisying the source code I concluded it will always results to false, so it is not needed. . some small code reorganization.

This patch implements changing resolution in zr364xx_vidioc_s_fmt_vid_cap for zr364xx driver. This version is synced with v4l-dvb as of 20/Jul/2009. Tested with Creative PC-CAM 880. OBS: I had to increase MAX_FRAME_SIZE to prevent a hard crash in my notebook (caps lock blinking) when testing with mplayer, which automatically sets resolution to the maximum (640x480). Maybe we should add code to auto-detect frame size to prevent this kind of crash in the future. Signed-off-by:

In automatic mode every stop event on SDA line ends repetition. However, in NetUP Dual card on the same i2c bus we have several devices. If someone using both adapters to lock simultaneously or working with CAM interface during lock procedure, it lead to end repetition prematurely quite often. Set stv0900 i2c repeater to manual mode prevents such situation. Signed-off-by:

The dvb-pll code should do the same thing that alps_tdee4_stv0297_tuner_set_params() was doing. Except the dvb-pll code will check for tuner presence when attaching, while the old code didn't. This tuner appears to not be behind the stv0297's I2C gate but is instead on a different I2C adapter provided by the flexcop chip. The old code would turn the I2C gate off each time the tuner was used. I've changed it to turn the gate off when the tuner is attached and then disable the gate control function. This should result in the gate staying off, which should be even better. [hverkuil@xs4all.nl: fix compile error] Signed-off-by:

The code in skystar23_samsung_tbdu18132_tuner_set_params() and samsung_tbmu24112_tuner_set_params() is equivalent to what the dvb-pll code does. There could be an issue because the dvb-pll code will probe to check for the tuner, while the previous code didn't do any checks. Signed-off-by:

Tuner parameters taken from flexcop driver. This PLL has a 17 bit divisor while the dvb-pll driver is designed for 15 bit divisors. It's not a problem as 15 bits is enough for the tuner's entire range. But if a larger range was wanted, it could be done by adding additional bands with the extra divisor bits appearing as band switch bits. Signed-off-by:

No datasheet, tuner data comes from code in flexcop driver. This tuner is also used on the AVerTV 771 supported by the bttv driver, but that code uses a different tuner configuration, which is surprising. Signed-off-by:

This patch implements V4L2_CAP_STREAMING for the zr364xx driver, by converting the driver to use videobuf. This version is synced with v4l-dvb as of 15/Jul/2009. Tested with Creative PC-CAM 880. It basically: . implements V4L2_CAP_STREAMING using videobuf; . re-implements V4L2_CAP_READWRITE using videobuf; . copies cam->udev->product to the card field of the v4l2_capability struct. That gives more information to the users about the webcam; . moves the brightness setting code from before requesting a frame (in read_frame) to the vidioc_s_ctrl ioctl. This way the brightness code is executed only when the application requests a change in brightness and not before every frame read; . comments part of zr364xx_vidioc_try_fmt_vid_cap that says that Skype + libv4l do not work. This patch fixes zr364xx for applications such as mplayer, Kopete+libv4l and Skype+libv4l can make use of the webcam that comes with zr364xx chip. Signed-off-by:

DMX_ADD_PID allows to add multiple PIDs to a transport stream filter previously set up with DMX_SET_PES_FILTER and output=DMX_OUT_TSDEMUX_TAP. DMX_REMOVE_PID is used to drop a PID from a filter. These ioctls are to be used by readers of /dev/dvb/adapterX/demuxY. They may be called at any time, i.e. before or after the first filter on the shared file descriptor was started. They make it possible to record multiple services without the need to de- or re-multiplex TS packets. To accomplish this, dmxdev_filter->feed.ts has been converted to a list of struct dmxdev_feeds, each containing a PID value and a pointer to a struct dmx_ts_feed. Signed-off-by:

In the past, some devices with saa711x had their parameters controlled directly inside em28xx driver, instead of using their proper module for it. Due to that, the ac97 controls were mixed with saa711x ones. Older patches removed all saa711x controls, but we still need to control ac97 devices on em28xx, since we don't have a separate v4l2 device for it. The proper way to address is to create a separate ac97 v4l2 device. While we don't have it, we should clean up the code to allow having a better view of what is part of em28xx core code and what's due to ac97 control inside it. Signed-off-by: -
