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.

"rc5 [rc6] nec jvc [sony]"

Writing "+proto" will add a protocol to the list of enabled

protocols.

Writing "proto" will enable only "proto".

Writing "none" will disable all protocols.

Write fails with EINVAL if an invalid protocol combination or
