2009-05-29cx18: Perform 64 bit divide so it works for 32 bit systemsAndy Walls
From: Andy Walls <awalls@radix.net> Thanks to David Ward and Mike Krufky for reporting the problem and debugging this as an unresolved symbol due to a 64 bit divide on a 32 bit system. David Ward provided the content of this patch; Andy Walls only performed some cosmetic edits.

2009-05-16cx18: Tweak color burst gate delay and initial color sub-carrier freqAndy Walls
From: Andy Walls <awalls@radix.net> Fix the burst gate delays to use a crystal value of 28636360 as assumed by the rest of the driver. Also have the initial color sub-carrier freq paramter use the src decimation ratio per the documentation, instead of the actual crystal/pixel clock ratio. The tracking circuit will find the correct color subcarrier in any case, as long as we're close. Also fix up some debug print statements. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2009-05-16cx18: Complete support for Sliced and Raw VBI for 625 line systemsAndy Walls
From: Andy Walls <awalls@radix.net> Finish changes for sliced and raw VBI for 625 line systems. Tested with VPS and WSS being emitted by a PVR-350 in field 1 lines 16 and 23. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>

2009-05-03cx18: Have audio decoder drive SIF gain control, and rework AFE configAndy Walls
From: Andy Walls <awalls@radix.net> Ensure the variable gain amplifier gain for SIF is driven by the audio deocder and not the video decoder. This forced rework of the analog front end (AFE) configuration to not rely on autoconfiguration, but instead set up the AFE mux, AFE parameters, and ADC1 & ADC2 configurations explicitly.

2009-04-02v4l2-subdev: change s_routing prototypeHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It is no longer needed to use a struct pointer as argument, since v4l2_subdev doesn't require that ioctl-like approach anymore. Instead just pass the input, output and config (new!) arguments directly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-04-01v4l2-subdev: move s_std from tuner to core.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> s_std didn't belong in the tuner ops. Stricly speaking it should be part of the video ops, but it is used by audio and tuner devices as well, so it is more efficient to make it part of the core ops. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-03-30v4l2-subdev: add load_fw and use that instead of abusing core->init.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The init callback was used in several places to load firmware. Make a separate load_fw callback for that. This makes the code a lot more understandable. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-03-30cx18: remove intermediate 'ioctl' stepHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The audio and vbi parts still used an 'ioctl'-like interface. Replace this with normal functions. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Andy Walls <awalls@radix.net>

2009-02-28cx18: Fix a video scaling check problem introduced by sliced VBI changesAndy Walls
From: Andy Walls <awalls@radix.net> Fix a scaling check that was failing, due to a magic number I missed fixing during previous slice VBI changes. Now $ v4l2-ctl -v width=480,height=480,pixelformat=MPEG yields proper visual results again. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>

2009-02-21cx18: Change log lines for internal subdevs and fix tveeprom readsAndy Walls
From: Andy Walls <awalls@radix.net> Give messages originating from internal subdevs a header using the subdev's name. Fixed an uninitialized variable problem with reading the EEPROM, noticed from log output. Got rid of the unused cx18_av_exit() function. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2009-02-21v4l2-common: remove v4l2_ctrl_query_fill_stdHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had. It doesn't add anything valuable that cannot be expressed equally well with v4l2_ctrl_query_fill and only adds overhead. Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it from v4l2_common.c. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-02-20cx18: Convert I2C devices to v4l2_subdevicesAndy Walls
From: Andy Walls <awalls@radix.net> This is a major perturbation to cx18 I2C device handling to convert it to the v4l2_device/subdeivce framework. This change breaks GPIO audio multiplexer control for the time being. It will be fixed in a coming change. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2009-02-16cx18, v4l2-chip-ident: Finish conversion of AV decoder core to v4l2_subdevAndy Walls
From: Andy Walls <awalls@radix.net> Added a new chip identifer to v4l2-chip-ident for the integrated A/V broadcast decoder core internal to the CX23418. Completed separation and encapsulation of the A/V decoder core interface as a v4l2_subdevice. The cx18 driver now compiles and links again.

2009-02-14cx18: Convert the integrated A/V decoder core interface to a v4l2_subdevAndy Walls
From: Andy Walls <awalls@radix.net> This is the next step in converting the cx18 driver to use the v4l2_device/ v4l2_subdevice framework. This is a straightforward conversion of the cx18_av_*[ch] files. It compiles, but leaves the driver in an unlinkable state at the moment. Note, the cx18 integrated A/V digitizer will now make a host match at address 1, as far as v4l2-dbg is concerned. That means it identifies itself as a separate "chip", and acts as an alias to the integrated A/V decoder registers that are also available with the host match at address 0.

2009-02-08cx18: Finally get sliced VBI working - for 525 line 60 Hz systems at leastAndy Walls
From: Andy Walls <awalls@radix.net> Sliced VBI, in the manner that ivtv implements it as a separate data stream, now works for 525 line 60 Hz systems like NTSC-M. It may work for 625 line 50 Hz systems, but I have more engineering work to do, to verify it is operating properly. Sliced data insertion into the MPEG PS should be working, but is untested.

2008-12-20cx18: Use a consistent crystal value for computing all PLL parametersAndy Walls
From: Andy Walls <awalls@radix.net> Use a consistent crystal value of 28.636360 MHz for computing all PLL parameters so clocks don't have relative error due to assumed crystal value mismatches. Also aimed to have all PLLs run their VOCs at close to 400 MHz to minimze the error of these PLLs as frequency synthesizers. Also set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware are loaded. Also fixed I2S Master clock dividers. Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and suggesting the solution, researching and experimenting, and performing extensive testing to support their suggested solution.

From: Andy Walls <awalls@radix.net> cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy so that write retries always occur and read retries never occur (as they never help). Remove MMIO statistics logging to speed up MMIO accesses. Deprecate & ignore retry_mmio and mmio_ndelay module parameters, to essentially force retry_mmio=1 and mmio_ndelay=0.

From: Andy Walls <awalls@radix.net> cx18: Fix PLL freq computation for debug display.

From: Andy Walls <awalls@radix.net> cx18: Fix write retries for registers that always change - part 3. Fix the io for the rest of the registers that will often not read back the value just written. Modified register readback checks to make sure the intended effect was achieved without constantly rewriting the registers.

2008-09-28cx18: Add default behavior of checking and retrying PCI MMIO accessesAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Add default behavior of checking and retrying PCI MMIO accesses. The concept of checking and retrying PCI MMIO accesses for better reliability in older motherboards was suggested by Steve Toth <stoth@linuxtv.org>. This change implements MMIO retries and the retry_mmio module parameter that is enabled by default. Limited experiments have shown this is more reliable than the mmio_ndelay parameter. mmio_ndelay has insignificant effect with retries enabled.
