Please drop those macros and use SENSOR_DEVICE_ATTR.. directly.

I am not really happy with the crit_temp attribute.
Usually we have just gave this another index, ie point5_temp.

Your code is missing the other two tables at register addresses 0x90+
and 0xa0+. Any reason for not including those ?

It might be better to use the attribute names we have used in other
drivers, ie pwm[123]_auto_point[1-5]_pwm and pwm[1-3]_auto_point[1-5]_temp
and support the other two tables as well. One option for the critical
pwm value might be to make it read-only and always report it as 255
for consistency.

Thanks,
Guenter
