* V4L/DVB: TM6000: Fix code which cause memory corruptionBee Hock Goh2010-05-19
| | | | | | | | | | The driver was doing malloc when buf is null causing memory corruption. The analog part is still pretty much broken but at least fixing this will stop it from crashing the machine when streamon.

* V4L/DVB: Fix default state Beholder H6 tunerDmitri Belimov2010-05-19
| | | | | | | | | | | | | | | | | | The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF. This tuner has internal I2C switch. This switch switch I2C bus between DVB-T and IF part. Default state is DVB-T. When module saa7134 is load it can't find IF tda9887 and disable analog TV mode. Sets internal I2C switch of the tuner to IF by send special value to the tuner as for receive analog TV from low band. It can be usefule for other cards. I didn't set configure a tuner by a tuner model because this tuner can have different I2C address. May be we can do it later after discuss for more robust support a tuners.

* Revert "V4L/DVB (11906): saa7134: Use v4l bounding/alignment function"Herton Ronaldo Krzesinski2010-05-19
| | | | | | | | | | | | | | | | | | | This reverts commit bc52d6eb44de8f19934768d4d10d19fdbdc99950. On newer kernels, a saa7134 board stopped to display TV video output properly. After a bisect, I found it as the commit causing the issue. Turns out that v4l_bound_align_image isn't doing the same bounding calculation as manually done previously in saa7134_try_fmt_vid_cap. What isn't equal is the calculation done in clamp align, while previously it did "f->fmt.pix.width &= ~0x03", clamp_align function does "Round to nearest aligned value" as stated in the comment, which yields a different result. If I comment the round calculation in clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask", I get it fixed too, because this way the calculation is the same then.

* V4L/DVB: ir-core: move subsystem internal calls to ir-core-priv.hMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | | | | | | | ir-core.h has the kABI to be used by the bridge drivers, when needing to register IR protocols and pass IR events. However, the same file also contains IR subsystem internal calls, meant to be used inside ir-core and between ir-core and the raw decoders. Better to move those functions to an internal header, for some reasons: 1) Header will be a little more cleaner; 2) It avoids the need of recompile everything (bridge/hardware drivers, etc), just because a new decoder were added, or some other internal change were needed; 3) Better organize the ir-core API, splitting the functions that are internal to IR core and the ancillary drivers (decoders, lirc_dev) from the features that should be exported to IR subsystem clients.

* V4L/DVB: Teach drivers/media/IR/ir-raw-event.c to use durationsDavid Härdeman2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | drivers/media/IR/ir-raw-event.c is currently written with the assumption that all "raw" hardware will generate events only on state change (i.e. when a pulse or space starts). However, some hardware (like mceusb, probably the most popular IR receiver out there) only generates duration data (and that data is buffered so using any kind of timing on the data is futile). Furthermore, using signed int's to represent pulse/space durations is a well-known approach when writing ir decoders. With this patch: - s64 int's are used to represent pulse/space durations in ns - a workqueue is used to decode the ir protocols outside of interrupt context - #defines are added to make decoders clearer - decoder reset is implemented by passing a zero duration to the kfifo queue and decoders are updated accordingly Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: ir-core: properly present the supported and current protocolsMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | | | | | Hardware decoders have a more limited set of decoders than software ones. In general, they support just one protocol at a given time, but allow changing between a few options. Rename the previous badly named "current_protocol" as just "protocol", meaning the current protocol(s) accepted by the driver, and add a "support_protocols" to represent the entire universe of supported protocols by that specific hardware. As commented on http://lwn.net/Articles/378884/, the "one file, one value" rule doesn't fit nor does make much sense for bitmap or enum values. So, the supported_protocols will enum all supported protocols, and the protocol will present all active protocols. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: ir-core: Distinguish sysfs attributes for in-hardware and raw decodersMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | Some devices have in-hardware Remote Controller decoder, while others need a software decoder to get the IR code. As each software decoder can be enabled/disabled individually, allowing multiple protocol decoding capability. On the other hand, hardware decoders have a limited protocol support, often being able of decoding just one protocol each time. So, each type needs a different set of capabilities to control the supported protocol(s). Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: rename sysfs remote controller devices from rcrcv to rcDavid Härdeman2010-05-19
| | | | | | | | | | | | | | When the remote controller class is anyway being renamed from ir to rc this would be a good time to also rename the devices from rcrcvX to rcX. I know we haven't reached any agreement on whether transmission will eventually be handled by the same device, but this change will at least make the device name non-receive-specific which will make it possible in the future (and if a different approach is finally agreed upon, the device name still works).
