2008-10-12V4L/DVB (8906): v4l-dvb: fix assorted sparse warningsHans Verkuil
Fix sparse warnings. None are serious, but cutting down on these helps find future serious sparse warnings/errors. Redid the av7710.c patch based on a suggestion by Oliver Endriss. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-12V4L/DVB (8901): pvrusb2: Disable virtual IR device when not needed.Mike Isely
Disable "virtual" IR receiver on for 24xxx devices that have an internal IR blaster. In that case there's another another IR receiver present and to leave the virtual receiver available just causes confusion. This means that 24xxx users will no longer see a phantom IR chip.

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.

The Zilog IR chip on HVR-1900 devices is held in reset when the device initializes. We have to bring this chip out of reset before LIRC has any chance of operating the chip. So do it. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-01-25V4L/DVB (6699): pvrusb2: Use of virtual IR chip is a device-specific attributeMike Isely
For Hauppauge 24xxx devices, the IR receiver is a custom piece of logic that is very specific to the device. The pvrusb2 driver can virtualize this to make it look like a more normal IR receiver found in other Hauppauge devices. The decision of whether or not to enable this virtualization however is a device-specific attribute, thus this changeset.

2008-01-25V4L/DVB (6692): pvrusb2: Centralize device specific attributes into a single ↵Mike Isely
place The pvrusb2 driver currently supports two variants of the Hauppauge PVR USB2. However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

2008-01-25V4L/DVB (6691): pvrusb2: Rework pipeline state controlMike Isely
This is a new implementation for video pipeline control within the pvrusb2 driver. Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

2007-10-09V4L/DVB (6212): pvrusb2: I2C adapter tweaks from Jean DelvareJean Delvare
* I2C adapters aren't expected to handle I2C_M_NOSTART unless they really have to. As the pvrusb2 driver doesn't support it, I take it that it doesn't need it so it shouldn't mention it at all. * I2C_FUNC_SMBUS_EMUL includes I2C_FUNC_SMBUS_BYTE_DATA so listing both is redundant.

2007-05-09V4L/DVB (5575): Pvrusb2: Implement ability to disable IR receiverMike Isely
Anyone using multiple PVR USB2 devices really only want one of them acting as the actual IR receiver. Implemented here is a new per-instance module option (ir_mode) which is a flag to enable the IR receiver. The default is enabled. IR reception is disabled by blocking access to the IR receiver chip in the device. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-12-10V4L/DVB (4763): Pvrusb2: Implement IR reception for 24xxx devicesMike Isely
Unlike 29xxx devices, the 24xxx model series does not have a dedicated I2C device for reception of IR codes. Instead IR is handled directly by the FX2 microcontroller and the results are communicated via commands to the FX2. Rather than implement a whole new IR reception pathway for 24xxx devices, this changeset instead emulates the presence of the 29xxx device's I2C based IR receiver by intercepting commands to that chip and issuing appropriate FX2 commands to do the needed action. This has the result of allowing all the usual IR frameworks (ir-kbd-i2c or lirc) to continue working unmodified for 24xxx devices.

2006-09-26V4L/DVB (4595): Remove CONFIG_VIDEO_PVRUSB2_24XXX from pvrusb2 driverMike Isely
Support for 24xxx devices was previously explicitly bracketed with CONFIG_VIDEO_PVRUSB2_24XXX inside the code because we didn't trust the stability of these changes.

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.
