I need to modify these bindings for upcoming v3 in the following ways:

* "actions,s500-timer", "actions,owl-timer" to deal with S500 vs. S900
differences while keeping a single driver registration (or would two
registrations be preferred, dropping the second compatible? they do
share a common subset)

* Use named interrupts to deal with 2x 2Hz + 2x Timer vs. 4x Timer for
complete hardware description

Andreas
