I was not expecting it to be totally arbitrary. I thought you would
have a real technical reason. Spaces often cause problems, as well as
/ etc.
I've had problems with hwmon device names breaking assumptions in the
user space code, etc. I was expecting something like this.
I don't really like the all lower case restriction. It makes it hard
to be consistent. All Marvell Docs refer to the Address Translation
Unit as ATU. I don't think there is any reference to atu. I would
prefer to be consistent with the documentation and use ATU. But that
is against your arbitrary rules.
