Heiner Kallweit 02212001c9 [media] media: rc: nuvoton: switch attribute wakeup_data to text
Switch attribute wakeup_data from binary to a text attribute.
This makes it easier to handle in userspace and allows to
use the output of tools like mode2 almost as is to set a
wakeup sequence.
Changing to a text format and values in microseconds also
makes the userspace interface independent of the setting of
SAMPLE_PERIOD in the driver.

In addition document the new sysfs attribute in
Documentation/ABI/testing/sysfs-class-rc-nuvoton.

Description:
Reading this file returns the stored CIR wakeup sequence.
It starts with a pulse, followed by a space, pulse etc.
All values are in microseconds.
The same format can be used to store a wakeup sequence
in the Nuvoton chip by writing to this file.
Note: Some systems reset the stored wakeup sequence to a
factory default on each boot. On such systems store the
wakeup sequence in a file and set it on boot using e.g.
a udev rule.
