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.
