* [media] rc: Remove ir-common moduleMauro Carvalho Chehab2010-12-292-7/+221
| | | | | | | | | | | | | | Now, just one old bttv board uses the old RC5 raw decoding routines. Its conversion to rc-core requires the generation of IRQ data for both positive and negative transitions at the IRQ line. I'm not sure if bttv driver supports it or if the transitions will be reliable enough. So, due to the lack of hardware for testing, the better for now is to just move the legacy routines to bttv driver, and wait for someone with a Nebula Digi could help to port it to use also rc-core raw decoders.

| | | | | | | | | The only IR left still using the old raw decoders on saa7134 is ENCORE FM 5.3. As it is now using the standard rc-core raw decoders, lots of old code can be removed from saa7134. Acked-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] ir-core: make struct rc_dev the primary interfaceDavid Härdeman2010-12-291-42/+30
| | | | | | | | | | | | | | | | | | | | | | This patch merges the ir_input_dev and ir_dev_props structs into a single struct called rc_dev. The drivers and various functions in rc-core used by the drivers are also changed to use rc_dev as the primary interface when dealing with rc-core. This means that the input_dev is abstracted away from the drivers which is necessary if we ever want to support multiple input devs per rc device. The new API is similar to what the input subsystem uses, i.e: rc_device_alloc() rc_device_free() rc_device_register() rc_device_unregister() [mchehab@redhat.com: Fix compilation on mceusb and cx231xx, due to merge conflicts] Signed-off-by: David Härdeman <david@hardeman.nu> Acked-by: Jarod Wilson <jarod@redhat.com> Tested-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] ir-core: more cleanups of ir-functions.cDavid Härdeman2010-12-291-1/+1
| | | | | | | | | | | | | | | | | | | | cx88 only depends on VIDEO_IR because it needs ir_extract_bits(). Move that function to ir-core.h and make it inline. Lots of drivers had dependencies on VIDEO_IR when they really wanted IR_CORE. The only remaining drivers to depend on VIDEO_IR are bt8xx and saa7134 (ir_rc5_timer_end is the only function exported by ir-functions). Rename VIDEO_IR -> IR_LEGACY to give a hint to anyone writing or converting drivers to IR_CORE that they do not want a dependency on IR_LEGACY.

| | | | | | | | | | | | | | | | | | | 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: Teach drivers/media/IR/ir-raw-event.c to use durationsDavid Härdeman2010-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Distinguish sysfs attributes for in-hardware and raw decodersMauro Carvalho Chehab2010-05-191-6/+3
| | | | | | | | | | | | | | 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: ir-nec-decoder: Reimplement the entire decoderMauro Carvalho Chehab2010-05-191-4/+5
| | | | | | | | | | | | | | | | | | | | | | | Thanks to Andy Walls <awalls@md.metrocast.net> for pointing me his code, that gave me some ideas to better implement it. After some work with saa7134 bits, I found a way to catch both IRQ edge pulses. By enabling it, the NEC decoder can now take both pulse and spaces into account, making it more precise. Instead of the old strategy of handling the events all at once, this code implements a state machine. Due to that, it handles individual pulse or space events, validating them against the protocol, producing a much more reliable decoding. With the new implementation, the protocol trailer bits are properly handled, making possible for the repeat key to work. Also, the code is now capable of handling both NEC and NEC extended IR devices. With NEC, it produces a 16 bits code, while with NEC extended, a 24 bits code is returned.

* V4L/DVB: saa7134: Add support for both positive and negative edge IRQMauro Carvalho Chehab2010-05-191-4/+6
| | | | | | | | | | | | | | | | | | | | The code that enables IRQ for the Remote Controller on saa7134 is a little messy: it is outside saa7134-input, it checks if RC is GPIO based, and it mixes both serial raw decode with parallel reads from a hardware-based IR decoder. Also, currently, it doesn't allow to trigger both transition edges at GPIO16 and GPIO18 lines. A rework on the code is needed to provide a better way to specify what saa7134-input needs, maybe even moving part of the code from saa7134-core and saa7134-cards into saa7134-input. Yet, as a large rework is happening at RC core, it is better to wait until the core changes stablize, in order to rework saa7134 RC internals.While this don't happen, let's just change the logic a little bit to allow enabling IRQ to be generated on both edge transitions, in order to better support pulse/space raw decoders.

* V4L/DVB: saa7134: Fix IRQ2 bit names for the register mapMauro Carvalho Chehab2010-05-193-20/+22
| | | | | | | | | | | | | | There's an error at the IRQ2 bit map registers. Also, it doesn't show what bits are needed for positive and for negative edge. In the case of IR raw decoding, for some protocols, it is important to detect both positive and negative edges. So, a latter patch will need to use the other values. Also, the code that detects problems on IRQ handling is incomplete, as it disables only one of the IRQ bits for GPIO16 and GPIO18. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
