I'm not sure this is really a good use of aliases. UARTs use aliases 
because it is important that the UART number to tty number is known and 
fixed. IIUC, as an example you are picking timer1 because it has 
properties X, Y and Z. If so, then you should describe those h/w 
properties within the timer nodes so you can pick which timer to use 
based on it's h/w properties.

Some GPTIMER blocks have input and output signals that can be routed to 
external package balls.  So it's possible that some application may need 
to request a specific timer ID, since that timer would be connected to a 
specific off-chip device.

Yes, I understand that. So you

(just to clarify, these are Jon's patches)

should be describing which ones have i/o and what they are connected to. 

Right, agreed.

The PWM binding is probably a starting point.

My point, perhaps unclear, was about the aliases.  Do you have a different 
approach in mind that applications should use, other than requesting a 
specific timer by ID?

Please disregard this question, I think I'm misunderstanding something 
from a previous mail...
