2008-10-12V4L/DVB (8900): pvrusb2: Implement cropping pass throughMike Isely
This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions.

2007-02-21V4L/DVB (5093): Pvrusb2: Emit VIDIOC_S_TUNER correctlyMike Isely
Audio mode changes are not private to the audio chip - other I2C modules need to see this as well. And since the command in question is VIDIOC_S_TUNER which is a standard v4l2 command, we really should be broadcasting it out. This change sets up a broadcast pathway for VIDIOC_S_TUNER and also eliminates the now redundant code from the audio chip handler. This fix enables stereo reception for the FM radio Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5081): Pvrusb2: VIDIOC_G_TUNER cleanupMike Isely
Clean up use of VIDIOC_G_TUNER; we now correctly gather info from all the I2C client modules. Also abide by V4L2_TUNER_CAP_LOW appropriately. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-21V4L/DVB (5051): Pvrusb2: Better radio versus tv frequency handlingMike Isely
Separate track radio versus tv frequency so that when we switch modes we can also switch to a sane frequency appropriate for the mode. Also implement logic to automate mode switching in certain cases. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5047): Pvrusb2: Fix tuning calculation when in radio modeMike Isely
Frequency units in V4L2 are apparently different when in radio mode compared to tv mode. Why? Who knows. This change adapts the driver appropriately - so that internally we always only deal in Hz and don't have to muck with craziness like this.

2007-02-21V4L/DVB (5046): Pvrusb2: Fix tuner frequency calculationMike Isely

Ensure we don't accidentally broadcast the standard while in radio mode. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5042): Pvrusb2: Make units uniform when tracking tuning frequencyMike Isely
The initial radio implementation used different units for tuning when in radio mode. This changes everything to Hz. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5035): Pvrusb2: Enable radio mode round #2Pantelis Koukousoulas
This is the logic that: a) Ensures /sys/class/pvrusb2/sn-*/ctl_frequency/{max,min}_val are "automagically" reset to sane values on each mode change. b) Allows tuning to a radio frequency by something like: echo `perl -e "print int(94.9*16000 + 0.5)"` \ > /sys/class/pvrusb2/sn-*/ctl_input/cur_val The trick was to take advantage of the already existing .get_{min,max}_value function pointers in pvr2_ctrl, to "dynamically override" the hardcoded values for min/max frequency at runtime. For a moment I thought to dispose of the hardcoded MIN/MAX_FREQ and use the hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that tuner-core.c kinda hardcodes these as well, so I decided to not bother.

2007-02-21V4L/DVB (5034): Pvrusb2: Enable radio mode round #1Pantelis Koukousoulas
This is the logic that supports switching modes via e.g., echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val. To do the mode switching we need to: a) broadcast AUDC_SET_RADIO and b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is done by adding a new pvr2_i2c_op and having it trigger on input change, the second by adding this command in pvr2_encoder_start() and requesting an encoder restart on input change by setting stale_subsys_mask appropriately. The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode switching this way (on input change) is due to Mike Isely. Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but I think this can be traced to a cornell student being the first to implement radio support in ivtv "as a different standard". I think the rest just evolved from there (it 's in the ivtv ML archives).

2006-06-27V4L/DVB (4228a): pvrusb2 to kernel 2.6.18Mike Isely
Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner. The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded cx23416 hardware MPEG2 encoder. There are two major variants of this device; this driver handles both. Any V4L2 application which understands MPEG2 video stream data should be able to work with this device.
