* V4L/DVB: cx25840: Add support for CX2388[57] A/V core integrated IR controllersAndy Walls2010-08-084-1/+1419
| | | | | | | | | | | | | | | | | | | | | | | | This patch is primarily a port of the integrated IR controller code in cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will really try to set up IR. This IR support, by design, still requires the bridge driver to do final IO pin mux configuration and setup of the IR controller parameters. For the CX2388[578] chips, enabling the AV Core for IR also starts sending Audio and Video interrupts to the bridge driver. For CX2388[578] chips audio and video interrupts are ignored and acknowledged when they happen. IR interrupt handling and status logging is exluded for the CX23888 which does not have an IR controller on the AV core. Note that experimentation reveals that the IR irq enables on the CX23885 have an inverted logic sense. The CX23887 likely suffers from the same quirk. For these chips, those irq enable bits are handled as interrupt disables. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | Also removed the bogus zeroing of fmt.sliced when setting up raw VBI. Switching between raw and sliced VBI changed in 2.6.28 and this memset should have been removed at that time. It was never noticed because the bridge driver will fill in the fmt.vbi values anyway.

* V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audioAndy Walls2010-02-261-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change attempts to fix the ivtv tinny audio problem by keeping digitizer to encoder audio clocks running, while disabling the video clocks as needed to avoid unpredictable PCI bus hangs. To accomplish this, for the cx25840 module enabling of audio streaming had to be separated from enabling video streaming, requiring an additional v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers. The cx231xx and cx23885 driver use the cx25840 module for affecting only video on s_stream calls, so those drivers needed no change. The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI bus hang, so the cx18 driver did not need corresponding changes. CX2341[56] based cards that are not using the CX2584x family of chips do not seem to be affected by the tinny audio problem, and this change should not affect how they are configured. It will delay their first capture by starting by another 300 msec though. Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and investigation of this problem will hopefully fix this problem once and for all for many ivtv users.

These cores all use slightly different sample clock schemes and may be assuming slightly (+/- 3 Hz) different reference frequencies. The code resuse was not worth the maintenance and testing headache of have all chips use the same function peppered with conditional logic. Added comments on how PLL and SRC parameters values are computed. Fixed a few bugs related to the shared code having a large number of conditional statements. Noted inconsistencies with FIXME in the comments. This is done in preparation for getting the CX2388[578] PLL/clock setting logic cleaned up for CX23888 analog video and IR (which need the VID PLL set right).

* V4L/DVB (13087): cx25840: Improve detection of CX2388[578] A/V coresAndy Walls2009-12-051-18/+79
| | | | | | | | | | | | | | | | | | | | Add improved logic to detect the exact CX2388[578] A/V core that is being probed. Also cleaned up detection and logging for CX2310[12], CX2583[67], and CX2584[0123] cores and chips. Also added code to identify a CX2388[578] A/V decoder core that is not responding properly. Typical symptoms include registers 0x00-0xff responding properly but all other registers returning the same value (0x13 and 0x5 have been observed). This state will cause proper detection of '885 vs. '887 vs. '888 to fail and the chip won't respond to get configured properly anyway. I have no method of reseting the core to a working state at this time; but I didn't try too hard to work one out either. The problem likely only occurs in development. I suspect configuring the SYS PLL VCO to oscillate too slowly (286.3 MHz?) before post divide may be the root cause, when encountered.
