I have run into situation with AT91 based products where I am at a
loss as to how to properly approproach implementing a driver/solution.
Several boards that I have dealt with are using the AT91's timer/counter pins
to emulate a simple clock output.
Currently, the only way I have found to emulate a clock output is to enable
the atmel,tcb-pwm driver and initialize the PWM from userspace using the
sysfs layer.
I would like to initialize the timer/counter in the kernel based on an entry
in the devicetree.
Does anyone have suggestion on how and where implement this?
