* [media] rc-core: merge rc5 and streamzap decodersDavid Härdeman2014-07-251-7/+1
| | | | | | | | | | | Now that the protocol is part of the scancode, it is pretty easy to merge the rc5 and streamzap decoders. An additional advantage is that the decoder is now stricter as it waits for the trailing silence before determining that a command is a valid rc5/streamzap command (which avoids collisions that I've seen with e.g. Sony protocols).

| | | | | | | | | | Commit 1d184b0bc13d ([media] media: rc: add raw decoder for Sharp protocol) added a new raw IR decoder for the sharp protocol, but didn't add the code to load the module at init as is done for other raw decoders, so add that code now.

* [media] media: rc: add raw decoder for Sharp protocolJames Hogan2014-02-041-0/+6
| | | | | | | | | | | | | | Add a raw decoder for the Sharp protocol. It uses a pulse distance modulation with a pulse of 320us and a bit period of 2ms for a logical 1 and 1ms for a logical 0. The first part of the message consists of a 5-bit address, an 8-bit command, and two other bits, followed by a 40ms gap before the echo message which is an inverted version of the main message except for the address bits.

* [media] rc-core: don't treat dev->rc_map.rc_type as a bitmapDavid Härdeman2013-03-231-1/+0
| | | | | | | | | | | | | | store_protocols() treats dev->rc_map.rc_type as a bitmap which is wrong for two reasons. First of all, it is pretty bogus to change the protocol type of the keymap just because the hardware has been asked to decode a different protocol. Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed out by James Hogan <james.hogan@imgtec.com>. Fix both issues by introducing a separate enabled_protocols member to struct rc_dev. Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] media/rc: fix oops on unloading module rc-coreKonstantin Khlebnikov2012-12-271-8/+8
| | | | | | | | | | | | | During modiles initialization rc-core schedules work which calls request_module() several times to load ir-*-decoder modules, but it does not wait or cancel this work on module unloading. rc-core should use request_module_nowait() instead, because it anyway cannot load modules synchronously or cancel/wait pending work on unloading, because this leads to deadlock on modules_mutex between several "modprobe" processes.

* [media] rc/ir-raw: use kfifo_rec_ptr_1 instead of kfifoJames Hogan2012-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | | Raw IR events are passed to the raw event thread through a kfifo. The size of the event struct is 12 bytes, and space for 512 events is reserved in the kfifo (6144 bytes), however this is rounded down to 4096 bytes (the next power of 2) by __kfifo_alloc(). 4096 bytes is not divisible by 12 therefore if the fifo fills up a third of a record will be written in the end of the kfifo by ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't have records). When this is read by ir_raw_event_thread() a corrupted or partial record will be read, and in the case of a partial record the BUG_ON(retval != sizeof(ev)) gets hit too. According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can handle records of a length between 0 and 255 bytes, so change struct ir_raw_event_ctrl to use that instead of struct kfifo.

* [media] rc-core support for Microsoft IR keyboard/mouseJarod Wilson2011-07-271-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a custom IR protocol decoder, for the RC-6-ish protocol used by the Microsoft Remote Keyboard, apparently developed internally at Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and transceiver requirements and specifications document, which also touches on this IR keyboard/mouse device. Its a standard keyboard with embedded thumb stick mouse pointer and mouse buttons, along with a number of media keys. The media keys are standard RC-6, identical to the signals from the stock MCE remotes, and will be handled as such. The keyboard and mouse signals will be decoded and delivered to the system by an input device registered specifically by this driver. Successfully tested with multiple mceusb-driven transceivers, as well as with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware with enough sampling resolution should be able to use this decoder, nothing about it is at all receiver-hardware-specific. This work is inspired by lirc_mod_mce: The documentation there and code aided in understanding and decoding the protocol, but the bulk of the code is actually borrowed more from the existing in-kernel decoders than anything. I did recycle the keyboard keycode table, a few defines, and some of the keyboard and mouse data parsing bits from lirc_mod_mce though. Special thanks to James Meyer for providing the hardware, and being patient with me as I took forever to get around to writing this. callback routine to ensure we don't get any stuck keys, and used symbolic names for the keytable. Also cc'ing Florian this time, who I believe is the original mod-mce author...

* [media] rc: rename the remaining things to rc_coreMauro Carvalho Chehab2010-12-291-1/+1
| | | | | | | | | | | | | | | The Remote Controller subsystem is meant to be used not only by Infra Red but also for similar types of Remote Controllers. The core is not specific to Infra Red. As such, rename: - ir-core.h to rc-core.h - IR_CORE to RC_CORE - namespace inside rc-core.c/rc-core.h To be consistent with the other changes. No functional change on this patch.

* [media] ir-core: make struct rc_dev the primary interfaceDavid Härdeman2010-12-291-8/+8
| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | [mchehab@redhat.com: this patch were originally bundled with some renaming stuff and with the file merges, as seen at: https://patchwork.kernel.org/patch/291092/. Instead of using the original approach, I wrote the rename patches and the code merge as separate changes, then applied the difference on this patch. This way, it is easier to see the real changes at the code, and will be easier to merge upstream, especially if some conflict rises on the renaming patches] 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>
