Well, from IEEE 1275, there defined a standard 'status' property indicating
The operational status of one device. The 'status' property has four possible
values: 'okay/ok', 'disabled', 'fail' and 'fail-xxx'.
If it is absent, that means the status of the device is unknown or okay.
If discard the status line here in vf610.dtsi, this device will be enabled
as default though 'no pins route out' on the board, and actually there has
pins route out on the board, as timer devices here we just not use it, but
as PWM devices the pins will be used.
How about let the node disabled in vf610.dtsi, and then enable it in vf610-twr.dts
if it will be used in TWR board... ?
Thanks,
