* [media] ir-rc5-decoder: print where decoding failsMauro Carvalho Chehab2014-07-301-2/+2
| | | | | | | | | | | The IR dprintk message that prints a RC5 decoding failure is not much helpful, as it doesn't tell on what bit the error occurred. Add such information, in order to make the debug message more useful. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] rc-main: allow raw protocol drivers to restrict the allowed protosMauro Carvalho Chehab2014-07-301-3/+2
| | | | | | | | | | | | | | On some hardware (au0828/au8522), the hardware is broken with regards to the initial pulse detection. So, the driver needs to produce a fake start pulse. That limits the acceptable protocols, as it is not possible to produce a fake pulse that would cover all supported protocols. So, allow the driver to explicitly set the allowed protocols. If the driver doesn't specify, keep the old behavior. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] mceusb: select default keytable based on vendorMauro Carvalho Chehab2014-07-271-6/+17
| | | | | | | | | | | | | | | | Some vendors have their on keymap table that are used on all (or almost all) models for that vendor. So, instead of specifying the keymap table per USB ID, let's use the Vendor ID's table by default. At the end, this will mean less code to be added when newer devices for those vendors are added. Of course, if rc_map is specified per board, it takes precedence. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] ati_remote: Better default keycodesGeorge Spelvin2014-07-251-10/+20
| | | | | | | | | | | | | | | | | | | This tries to make them more like other remotes, and/or the button labels. Notably, the (>>) button is made KEY_FASTFORWARD, which is the correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD, something else entirely.) Likewise, KEY_STOP is the Sun keyboard "interrupt program" key; the media key is KEY_STOPCD. A restriction is that I try to avoid keycodes above 255, as the X11 client/server protocol is limited to 8-bit key codes. If not for this, I would have used the KEY_NUMERIC_x codes for the numbers.

* [media] rc-core: merge rc5 and streamzap decodersDavid Härdeman2014-07-257-218/+43
| | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | The basic API of rc-core used to be: dev = rc_allocate_device(); dev->x = a; dev->y = b; dev->z = c; rc_register_device(); which is a pretty common pattern in the kernel, after the introduction of protocol arrays the API looks something like: dev = rc_allocate_device(); dev->x = a; rc_set_allowed_protocols(dev, RC_BIT_X); dev->z = c; rc_register_device(); There's no real need for the protocols to be an array, so change it back to be consistent (and in preparation for the following patches).

| | | | | | | | | | | This driver codes the two address bytes in reverse order when compared to the other drivers, so make it consistent (and update the keymap, note that the result is a prefix change from 0x6b86 -> 0x866b, and the latter is pretty common among the NECX keymaps.

This patch (which required reading through the source/keymap for all drivers, not fun) makes the protocol information explicit which is important documentation and makes it easier to e.g. support multiple protocols with one decoder (think rc5 and rc-streamzap).

The original patch ignored the fact that NEC32 scancodes are generated not only in the NEC raw decoder but also directly in some drivers. Whichever approach is chosen it should be consistent across drivers and this patch needs more discussion.

* [media] rc-main: automatically refresh filter on protocol changeJames Hogan2014-03-111-2/+39
| | | | | | | | | | | | | | | | | | | | | | | When either of the normal or wakeup filter protocols are changed, refresh the corresponding scancode filter, i.e. try and set the same scancode filter with the new protocol. If that fails clear the filter instead. If no protocol was selected the filter is just cleared, and if no s_filter callback exists the filter is left unmodified. Similarly clear the filter mask when the filter is set if no protocol is currently selected. This simplifies driver code which no longer has to explicitly worry about modifying the filter on a protocol change. This also allows the change_wakeup_protocol callback to be omitted entirely if there is only a single available wakeup protocol at a time, since selecting no protocol will automatically clear the wakeup filter, disabling wakeup.

* [media] rc: add wakeup_protocols sysfs fileJames Hogan2014-03-111-34/+48
| | | | | | | | | | | | | Add a wakeup_protocols sysfs file which controls the new rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of protocols that are used for the wakeup filter. A new RC driver callback change_wakeup_protocol() is called to change the wakeup protocol mask.
