2013-08-22[media] winbond: wire up rc feedback ledSean Young2-33/+6
Note that with the rc-feedback trigger, the cir-rx trigger is now redundant. The cir-tx trigger is not used by default; if this functionality is desired then it should exist in rc-core, not in a driver. Also make sure that the led is suspended on suspend.

2013-07-31[media] media: lirc: Allow lirc dev to talk to rc deviceSrinivas Kandagatla2-0/+11
The use case is simple, if any rc device has allowed protocols = RC_TYPE_LIRC and map_name = RC_MAP_LIRC set, the driver open will be never called. The reason for this is, all of the key maps except lirc have some KEYS in there map, so during rc_register_device process these keys are matched against the input drivers and open is performed, so for the case of RC_MAP_EMPTY, a vt/keyboard is matched and the driver open is performed. In case of lirc, there is no match and result is that there is no open performed, however the lirc-dev will go ahead and create a /dev/lirc0 node. Now when lircd/mode2 opens this device, no data is available because the driver was never opened. Other case pointed by Sean Young, As rc device gets opened via the input interface. If the input device is never opened (e.g. embedded with no console) then the rc open is never called and lirc will not work either. So that's another case. lirc_dev seems to have no link with actual rc device w.r.t open/close. This patch adds rc_dev pointer to lirc_driver structure for cases like this, so that it can do the open/close of the real driver in accordance to lircd/mode2 open/close. Without this patch its impossible to open a rc device which has RC_TYPE_LIRC ad RC_MAP_LIRC set.

2013-07-31[media] media: rc: Add rc_open/close and use count to rc_devSrinivas Kandagatla1-4/+42
This patch adds user count to rc_dev structure, the reason to add this new member is to allow other code like lirc to open rc device directly. In the existing code, rc device is only opened by input subsystem which works ok if we have any input drivers to match. But in case like lirc where there will be no input driver, rc device will be never opened. Having this user count variable will be usefull to allow rc device to be opened from code other than rc-main. This patch also adds rc_open and rc_close functions for other drivers like lirc to open and close rc devices. This functions safely increment and decrement the user count. Other driver wanting to open rc device should call rc_open and rc_close, rather than directly modifying the rc_dev structure.

2013-04-08[media] MEDIA: ttusbir, fix double freeJiri Slaby1-0/+1
rc_unregister_device already calls rc_free_device to free the passed device. But in one of ttusbir's probe fail paths, we call rc_unregister_device _and_ rc_free_device. This is wrong and results in a double free. Instead, set rc to NULL resulting in rc_free_device being a noop.

2013-03-23[media] rc-core: don't treat dev->rc_map.rc_type as a bitmapDavid Härdeman12-38/+25
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>

Some imon devices (like 15c2:0036) need a higher delay between send_packet calls. Default value is still 5ms to avoid regressions on already working hardware.

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Similarly probe() methods should not be marked __init unless platform_driver_probe() is used.
