* V4L/DVB (13089): cx25840: Separate set_audclk_freq functionality for the ↵Andy Walls2009-12-05
| | | | | | | | | | | | | | | | | | | | different chips Separate out the set_audclk_freq() function into separate functions for the four families of cores. 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 (13088): cx25840: Convert chip/core family checks to static inline ↵Andy Walls2009-12-05
| | | | | | | | | | | | functions Change logic to check for various chip or core families to inline functions. Checks for specific chips should be made against the state->id field now. This is in preparation for chip/core specific code for setting up PLLs for the CX2388[578] family of cores, that all run with different crystal frequencies.

| | | | | | | | cx231xx has a cx25840 inside the chip. However, some different initializations are used for this variant. Signed-off-by: Srinivasa Deevi <srinivasa.deevi@conexant.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (11309): cx25840: cleanup: remove intermediate 'ioctl' stepHans Verkuil2009-03-30
| | | | | | | | | The audio and vbi functions where still called through an ioctl-like interface, even though this is no longer needed with v4l2-subdev. Just change each 'case' into a proper function and call that directly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (7002): cx25840: Add basic CX23885 AVCore supportSteven Toth2008-01-25
| | | | | | | | | | The cx23885/7/8 PCIe bridge has an internal AVCore modelled on the cx2584x family. Many of the registers positions are identical but some moved. The register values are also different because the different bridges run at different clock rates.

* V4L/DVB (6743): cx25840: fix endianness inconsistencyHans Verkuil2008-01-25
| | | | | | | | | cx25840_read4 reads a little-endian 32-bit value whereas cx25840_write4 writes the 32-bit value as big-endian. Convert write4 to use little-endian as well (that's the correct endianness). Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (5997): cx25840: fix audio mute handling and reportingHans Verkuil2007-10-09
| | | | | | | | | | | | | | | | Audio muting for the tuner input was implemented by stopping the audio microcontroller and restarting it on unmute. However, it appears that this method can actually crash the audio firmware. It's rare and seems to happen with NTSC only. It has been reimplemented by setting to volume to 0. In addition, the reporting of the mute state has been improved as well: it used to be impossible to detect whether the audio was muted by the user or if it was muted due to the microcontroller trying to detect the audio standard. This is now clearly stated. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (3577): Cleanup audio input handlingHans Verkuil2006-03-24
| | | | | | | | | | | | | | | | | | | | | | Cleanup audio input handling in bttv and tvaudio: - inputs were specified that were never used - mute was handled as a special input which led to confusing code - confusing naming made it difficult to see if the setting was for i2c or gpio. The old audiochip.h input names moved to tvaudio.h. Currently this is used both by tvaudio and msp3400 until the msp3400 implements the new msp3400-specific inputs. Detect in bttv the tvaudio and msp3400 i2c clients and use these client pointers to set the inputs directly instead of broadcasting the command. Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be replaced again later by the new ROUTING commands. Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is a user level command and not to be used internally. It wasn't called at all anyway.

* V4L/DVB (3249): Generalized cx25840 video/audio input handlingHans Verkuil2006-01-09
| | | | | | | | | | | | | | - Added VIDIOC_S_AUDIO to set the audio inputs separately. - Removed AUDC_SET_INPUT. - Made the video inputs much more general. - Removed cardtype CID and replaced with a CID to enable the PVR150 workaround. The cardtype is no longer necessary with the general video input change. - Update VIDIOC_LOG_STATUS output to show the video and audio inputs separately.

| | | | | | | | | | | - Calculate the audio master clock registers from the actual frequencies. This simplifies the code and it also prepares for adding CGC2 support. - VIDIOC_INT_AUDIO_CLOCK_FREQ now receives an u32 instead of an enum. It is more generic and actually easier to implement.
