2008-01-09cx25840: Add basic CX23885 AVCore supportSteven Toth
From: Steven Toth <stoth@hauppauge.com> 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. Signed-off-by: Steven Toth <stoth@hauppauge.com>
2007-12-02cx25840: fix endianness inconsistencyHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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>

From: Hans Verkuil <hverkuil@xs4all.nl> If the chip isn't recognized, then the correct errors should be returned. The v4l2_i2c_attach() utility function will return 0 for all errors except -ENOMEM to provide proper compatibility support for the old I2C probing function.

2007-08-28cx25840: add a few 10 microsecond delaysHans Verkuil
From: Tyler Trafford <ttrafford@gmail.com> There were a couple of places in the cx25840 initialization where the datasheet called for a 10 microsecond delay, which we ignored because of the 10 usec I2C delay. Put them in anyway now that the I2C delay was decreased to 5 usec. Signed-off-by: Tyler Trafford <ttrafford@gmail.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-26cx25840: use a workqueue to load the firmwareHans Verkuil

2007-08-05cx25840: fix audio mute handling and reportingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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>
2007-08-04cx25840: resetting also requires reloading the firmwareHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Resetting without reloading the firmware is not enough. Sometimes the firmware is 'stuck' and needs to be reloaded. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-22ivtv, cx25840: postpone fw load until first use.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The firmware is now loaded when the driver is actually used for the first time. This allows the driver to be compiled in-kernel instead of as a module. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-04-29Improve / fix support for PAL-60 in cx25840Mike Isely
From: Servaas Vandenberghe <vdb128@picaros.org> This causes the cx25840 module to treat V4L2_STD_PAL_60 similar to other 60Hz timings, and it fixes a wrongly-named variable (timings are independant of color system).

2007-02-27Improve VIDIOC_G_CHIP_IDENT (better diagnostics)Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Simplify the VIDIOC_G_CHIP_IDENT implementation by adding a single common function. The ident can now also return NONE: not found, UNKNOWN: found, but we don't know what chip it is, and AMBIGUOUS: multiple chips were matched so the match values were too general. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-24Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Jonathan Corbet <corbet@lwn.net>
2007-02-24Improve chip matching in v4l2_register for VIDIOC_DBG_G/S_REGISTERHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The chip matching in struct v4l2_register was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to differentiate between two i2c chips driven by the same driver on one board (e.g. a PVR500 with two tuner chips, one for analog TV and one for radio). It has now been improved making it much more powerful. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Mike Isely <isely@isely.net> CC: Trent Piepho <xyzzy@speakeasy.org>
2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-02-15Fix cx25840 firmware loading.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Due to changes in the i2c handling in 2.6.20 this cx25840 bug surfaced, causing the firmware load to fail for the ivtv driver. The correct sequence is to first attach the i2c client, then use the client's device to load the firmware. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Acked-by: Mike Isely <isely@pobox.com>

2007-02-05cx25840 request_firmware failed due to wrong device.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Due to changes in the /sys directory structure a bug in the cx25840 firmware load surfaced in 2.6.20: the device passed to request_firmware was wrong: instead of the i2c device the i2c adapter was passed. Because of this an attemp was made to create a kobject with the adapter name inside the adapter directory, but a kobject with that name already exists. Now pass the i2c device itself so that the correct /sys directory is used. This way the firmware can be loaded again. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-01-30Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTERTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Before, root privileges were only needed to set hardware registers, not to read them. On some hardware, reading from the wrong place at the wrong time can hang the machine. So, to be consistent, root privileges are required to read registers on all hardware. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-01-23Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2006-03-29Reverted sliced VBI API changes made in videodev2.h.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The sliced VBI defines added in videodev2.h are removed. One define changed the meaning of a old define, thus breaking existing apps, another used more than 16 bits (the max size is u16), and many types were added that were untested and whose payload was undocumented. New types should be shown to exist 'in the wild' and the payload format must be documented in the V4L2 API spec. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-25Reduce FWSEND in cx25840 module due to certain I2C bus adapter limitsMike Isely
From: Mike Isely <isely@pobox.com> The FWSEND parameter controls the size of the firmware chunks sent down the I2C bus to the chip. Previously this had been set to 1024 but unfortunately some I2C implementations can't transfer data in such big gulps. Specifically, the pvrusb2 driver has a hard limit of around 60 bytes, due to the encapsulation there of I2C traffic into USB messages. So we have to significantly reduce this parameter.

From: Hans Verkuil <hverkuil@xs4all.nl> Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER). This mode allows the user to select both languages of a bilingual transmission, one language on the left, one on the right audio channel. If there is no bilingual transmission, or it is not supported, then this mode should act like V4L2_TUNER_MODE_STEREO. This mode is introduced for PVR-like drivers where it is useful to be able to record both languages of a bilingual broadcast. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2006-03-19Cleanup audio input handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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.
