[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.

media: update/fix my e-mail on some places There are two places pointing to an unexisting "m.chehab@kernel.org" email. I never had such email, so, I'm unsure how it ends there. Anyway, it is plain wrong. While here, use my canonical e-mail on a bunch of places that are pointing to another e-mail. The idea is that, from now on, all places will be pointing to the same SMTP server. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

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.
