* V4L/DVB: bttv-driver: document functions using mutex_lockMauro Carvalho Chehab2010-10-20
| | | | | | | | | There are a few ancillary static routines used by ioctl functions that takes bttv lock internally. As we'll be adding the same lock for all ioctl's that need, we need to properly document them, to avoid doing double locks Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: dvb/bt8xx: kill the big kernel lockArnd Bergmann2010-10-20
| | | | | | | | | The bt8xx driver only uses the big kernel lock in its dst_ca_ioctl function and never to serialize against other code, so we can trivially replace it with a private mutex. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: dvb-core: kill the big kernel lockArnd Bergmann2010-10-20
| | | | | | | | | | | The dvb core only uses the big kernel lock in the open and ioctl functions, which means it can be replaced with a dvb specific mutex. Fortunately, all the ioctl functions go through dvb_usercopy, so we can move the serialization in there.

| | | | | | | | | | Code in function cx22702_set_tps() can be slightly simplified. Apparently gcc was smart enough to optimize it anyway, but it can't hurt to make the code more readable.

* V4L/DVB: cx22702: Some things never changeJean Delvare2010-10-20

* V4L/DVB: tvaudio: remove obsolete tda8425 initializationHans Verkuil2010-10-20
| | | | | | | | | | | | The tda8425 initialization function sets up the inputmap for riva boards. After some digging I discovered that this was for the V4L rivatv driver that is found on sourceforge. This driver hasn't been maintained since the last 5 years and will no longer work with the current v4l framework. So we can safely remove this.

* V4L/DVB: IR/imon: set up mce-only devices w/mce keytableJarod Wilson2010-10-20
| | | | | | | | | | | | Currently, they get set up with the pad keytable, which they can't actually use at all. Also add another variant of volume scancodes from another 0xffdc device, and properly set up the 0x9e 0xffdc device as an iMON VFD w/MCE proto IR. Based on data and a prior patch from Anders Eriksson on the lirc list. Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: IR/imon: protect ictx's kc and last_keycode w/spinlockJarod Wilson2010-10-20
| | | | | | | | | | Lest we get our keycodes wrong... Thus far, in practice, I've not found it to actually matter, but its one of the issues raised in https://bugzilla.kernel.org/show_bug.cgi?id=16351 that wasn't addressed by converting to using native IR keydown/up functions.

* V4L/DVB: imon: split mouse events to a separate input devDavid Härdeman2010-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a stab at separating the mouse (and front panel/knob) events out to a separate input device. This is necessary in preparation for the next patch which makes the rc-core input dev opaque to rc drivers. I can't verify the correctness of the patch beyond the fact that it compiles without warnings. The driver has resisted most of my attempts at understanding it properly...for example, the double calls to le64_to_cpu() and be64_to_cpu() which are applied in imon_incoming_packet() and imon_panel_key_lookup() would amount to a bswab64() call, irregardless of the cpu endianness, and I think the code wouldn't have worked on a big-endian machine... - Minor alterations to apply with minimal core IR changes - Use timer for imon keys too, since its entirely possible for the receiver to miss release codes (either by way of another key being pressed while the first is held or by the remote pointing away from the recevier when the key is release. yes, I know, its ugly). - Bump driver version number, since this is a fairly significant change (for the much much better). Tested successfully w/an imon knob receiver. Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: IR: export ir_keyup so imon driver can use it directlyJarod Wilson2010-10-20
| | | | | | | | | | | | | | | | The imon driver currently reimplements its own version of ir_keyup (along with key release timer functionality also already present in the core IR code). A follow-up imon patch will make use of ir_keyup and the IR stack's key release code. Trivial extraction from David Härdeman's pending rc-core merge and device interface abstraction patchset to facilitate merging a patch based on his imon input dev split patch ahead of the larger churn, which is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are merged in mainline).

* V4L/DVB: saa7134: get rid of I2C_HW_SAA7134Mauro Carvalho Chehab2010-10-20
| | | | | | | | The only reason for keeping I2C_HW_SAA7134 is to allow setting a per-device polling interval. Just move this info to the platform data, allowing drivers to change it per device, where needed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: Remove the usage of I2C_HW_B_CX2388x on ir-kbd-i2c.cMauro Carvalho Chehab2010-10-20
| | | | | | | | | | | | | | Move the cx88 specific initialization for Hauppauge XVR remotes into cx88-input, removing the need for test it inside ir-kbd-i2c. The reference at cx88 for this symbol, at: drivers/media/video/cx88/cx88-i2c.c: core->i2c_adap.id = I2C_HW_B_CX2388x; drivers/media/video/cx88/cx88-vp3054-i2c.c: vp3054_i2c->adap.id = I2C_HW_B_CX2388x; Can't be removed yet, since lirc-i2c still uses it.

* V4L/DVB: usbvision: remove BKL from usbvisionHans Verkuil2010-10-20
| | | | | | | | | | | | | | | | Removed the BKL from usbvision. There was an initialization bug as well where the i2c bus was registered twice. Although when the BKL was present no oops was generated, I did run into other i2c problems. Now that I protect against duplicate i2c registration that bug is now gone as well. But trying to disconnect the USB cable while someone is still using the device still leads to a crash.

* V4L/DVB: v4l: remove obsolete include/media/v4l2-i2c-drv.h fileHans Verkuil2010-10-20
| | | | | | | | | | | | | | The include/media/v4l2-i2c-drv.h header was used to be able to compile drivers in the v4l-dvb hg repository for legacy kernels (mainly pre-2.6.26) without creating an #ifdef mess. The hg repository dropped support for kernels < 2.6.26 so we can remove this header. All i2c drivers that used it have now been converted to use proper i2c code. The header was a hack, but it did its job well. So I would call this an honorable removal. :-) Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
