Sean Young febfe985fc media: ir_toy: assignment to be16 should be of correct type
commit f0c15b360f ("media: ir_toy: prevent device from hanging during
transmit") removed a cpu_to_be16() cast, which causes a sparse warning.

Sean Young 4114978dcd media: ir_toy: prevent device from hanging during transmit
If the IR Toy is receiving IR while a transmit is done, it may end up
hanging. We can prevent this from happening by re-entering sample mode
just before issuing the transmit command.

Sean Young 1d37c85425 media: ir_toy: deal with residual irdata before expected response
After sending the start transmit command, the device is supposed to
respond with the length of the buffer which can be sent. There might
be some residual ir data there.

Sean Young 528222d853 media: rc: harmonize infrared durations to microseconds
rc-core kapi uses nanoseconds for infrared durations for receiving, and
microseconds for sending. The uapi already uses microseconds for both,
so this patch does not change the uapi.

Infrared durations do not need nanosecond resolution. IR protocols do not
have durations shorter than about 100 microseconds. Some IR hardware offers
250 microseconds resolution, which is sufficient for most protocols.
Better hardware has 50 microsecond resolution and is enough for every
protocol I am aware off.

Unify on microseconds everywhere. This simplifies the code since less
conversion between microseconds and nanoseconds needs to be done.

This affects:
 - rx_resolution member of struct rc_dev
 - timeout member of struct rc_dev
 - duration member in struct ir_raw_event
