Hi Simon,

Shall we have a timer class in driver model?

I am trying to get the base address and clock rate of timer from device 
tree, and use them for timer_init() in common/board_f.c and lib/time.c .

As almost every board needs a timer, I wonder if it makes sense to use 
driver model? Or shall I use fdtdec to do the binding?

timer_init() sits after initf_dm() in common/board_f.c will this work?

Best regards,
Thomas Chou

Yes I guess so. We will need it sooner or later. You could add a
microsecond API also.

Thanks for the help. I will try to add a timer uclass soon. I am all new 
to the driver model though.

Best regard,
