2006-05-07bug-fix: pvrusb2 must #include <linux/config.h> for compile-time optionsMichael Krufky
From: Michael Krufky <mkrufky@linuxtv.org> Added necessary header file in order for kconfig build options to be considered at compile time. Without this patch all options will always be disabled, regardless of whether they are selected or not. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Acked-by: Mike Isely <isely@pobox.com>
2006-04-20Implement I2C filter in pvrusb2 for cx25840Mike Isely
From: Mike Isely <isely@pobox.com> Insert an I2C transaction filter for the cx25843 chip on new model 24xxx hardware. This filter attempts to stabilize the part by limiting how the part can be accessed. The filter won't allow anyone to touch the chip until an attempt is made to specifically read the chip's revision registers. If that read fails (which can happen if the chip wedges itself), a warning is logged and the driver is rendered useless. If the read succeeds, then the filter deletes itself and normal access to the part takes place. This filter should keep msp3400 away from the chip (a failure scenario which otherwise frequently ends badly for the kernel, due to suspected misbehaviors within the msp3400 module).

2006-04-20Implement I2C transaction filtering in pvrusb2Mike Isely
From: Mike Isely <isely@pobox.com> Implement a rudimentary filter mechanism in the I2C adapter within the pvrusb2 driver. It is possible now to interpose a filtering function on a per-target basis. This function can intercept the requested transaction and perform various manipulations on behalf of the client. With this mechanism is also a filter inserted for wm8775 that causes all probe attempts to the chip to always succeed (just return success on probe attempts without touching the hardware). This neatly solves the problem in the PVR USB2 hardware where we can't seem able to probe the chip at all. Signed-off-by: Mike Isely <isely@pobox.com>
2006-04-20Include linux/mutex.h not asm/mutex.h in pvrusb2Mike Isely
From: Mike Isely <isely@pobox.com> The correct mutex header to grab is linux/mutex.h, and while asm/mutex.h seems to work for x86 architecture, it has been reported not to work for amd64 architecture. So let's just do this right. Signed-off-by: Mike Isely <isely@pobox.com>
2006-04-19Another rework of pvrusb2 video standard handlingMike Isely
From: Mike Isely <isely@pobox.com> Clean up logic for handling video standards in the pvrusb2 driver. New implementation should be able to handle all possible V4L defined video standards now, and it should be far easier to maintain this going forward. Signed-off-by: Mike Isely <isely@pobox.com>
2006-04-19Rework pvrusb2 internal controls implementationMike Isely
From: Mike Isely <isely@pobox.com> Rework controls internal architecture. Rework video standard handling. This is a major change. Signed-off-by: Mike Isely <isely@pobox.com>
2006-04-01Split out PVR USB2 model 24xxx hardware support to a config optionMike Isely
From: Mike Isely <isely@pobox.com> Since there are lingering stability problems with support of the newer PVR USB2 model 24xxx series hardware, I have isolate those changes with a config option. This commit leaves that option off. Signed-off-by: Mike Isely <isely@pobox.com>
2006-03-28Major pvrusb2 rework to remove translationsMike Isely
From: Mike Isely <isely@pobox.com> Rework entire internal controls interface to eliminate the need for visibly defined control IDs which must otherwise be translated by the V4L2 public interface. As part of this work, internal structures which mimiced various V4L2 structures (video standards, audio modes) have been reworked to actually use the native structures. This triggered a _significant_ rework for how video standards are dealt with (and what is in place now should be much more flexible and forgiving for various handling less-common video standards).

2006-03-26Get rid of static PVR2_CID_COUNT in pvrusb2Mike Isely
From: Mike Isely <isely@pobox.com> Eliminate the need to track the number pvrusb2 CIDs at compile time from within the pvrusb2 driver. This is part of a control structure cleanup. Signed-off-by: Mike Isely <isely@pobox.com>
2006-03-25Implement method in pvrusb2 to force the decoder to resetMike Isely
From: Mike Isely <isely@pobox.com> This change threads logic through the pvrusb2 to make it possible to command the decoder chip to reset itself. The method is decoder-agnostic; the part of the pvrusb2 which control's that chip's module has to provide the final hook. This just lays the foundation. Signed-off-by: Mike Isely <isely@pobox.com>
2006-03-10Make pvrusb2 aware of alternative hardware typesMike Isely
From: Mike Isely <isely@pobox.com> Notice and track actual hardware type of device. This information is also used now to select the correct FX2 firmware file to load (because they can be different, unfortunately). Signed-off-by: Mike Isely <isely@pobox.com>
