2009-03-08pvrusb2: Remove old i2c layer; we use v4l2-subdev nowMike Isely
From: Mike Isely <isely@pobox.com> This change removes the old i2c module controlling layer from the pvrusb2 driver. This is code that first had appeared in the driver back in December 2005. It's history. Now we use v4l2-subdev. Please note also that with this change, the driver will no longer be usable in kernels older that 2.6.22.

2009-03-06pvrusb2: Implement mechanism to force a full sub-device updateMike Isely
From: Mike Isely <isely@pobox.com> When a pvrusb2 driver instance first initializes, we need to be sure to send out a complete state update for everything to all attached modules. The old i2c layer did this by keeping a separate mask of "stale" bits for each attached module - and setting that mask to all stale when that module attaches. But the new sub-device adaptation I've implemented here no longer has per-module stale bits. So instead there's now a global "force dirty" bit that is set upon instance initialization, before the sub-devices are attached. After the first update, this bit is cleared, allowing for normal update-on-dirty behavior. In this manner, we ensure that all sub-devices have been properly synchronized at initialization.

2007-11-25pvrusb2: Enable support for "GOTVIEW USB2.0 DVD2" hardwareMike Isely
From: Mike Isely <isely@pobox.com> This changeset allows the pvrusb2 driver to operate a new device type ("GOTVIEW USB2.0 DVD2"). Changes amount to defining a new routing scheme for the device and adding appropriate table entries into pvrusb2-devattr.c. Signed-off-by: Mike Isely <isely@pobox.com>
2007-11-25pvrusb2: Implement signal routing schemesMike Isely
From: Mike Isely <isely@pobox.com> The exact routing of video and audio signals within a device is a device-specific attribute. Hauppauge devices do it one way; other types of device may route things differently. Unfortunately it is rather impractical to define chip-specific routing at the device attribute level, so instead what happens here is that "schemes" are defined. Each chip level interface implements its part of a given scheme and the scheme as a whole is made into a device specific attribute controlled via a table entry in pvrusb2-devattr.c. The only scheme defined here is for Hauppauge devices, but clearly this opens the door for other possibilities to follow. Signed-off-by: Mike Isely <isely@pobox.com>
2007-11-25pvrusb2: Rework pipeline state controlMike Isely
From: Mike Isely <isely@pobox.com> 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.

2007-02-19compat: 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>

From: Mike Isely <isely@pobox.com> Fix long-standing issue which prevented use of 24xxx devices at any horizontal resolution other an 720. The problem is in the cx25840 module, if no attempt is made to initialize VBI there. Such a thing should not be needed, but the pvrusb2 driver is updated now to deal with this.
