5*4882a593SmuzhiyunDescription:
6*4882a593Smuzhiyun		Reading this file returns the stored CIR wakeup sequence.
7*4882a593Smuzhiyun		It starts with a pulse, followed by a space, pulse etc.
8*4882a593Smuzhiyun		All values are in microseconds.
9*4882a593Smuzhiyun		The same format can be used to store a wakeup sequence
10*4882a593Smuzhiyun		in the Nuvoton chip by writing to this file.
11*4882a593Smuzhiyun
12*4882a593Smuzhiyun		Note: Some systems reset the stored wakeup sequence to a
13*4882a593Smuzhiyun		factory default on each boot. On such systems store the
14*4882a593Smuzhiyun		wakeup sequence in a file and set it on boot using e.g.
15*4882a593Smuzhiyun		a udev rule.
