Kernel API's for ADC

[chandrasekhar]

I am using freescale IMX6UL processor. I have to do it in kernel space, I
have a thermal printer attached to the processor and I have to continuously
monitor temperature of the printer head inorder to change he printing time
values. 
So based on the temperature values I have to decide dynamically how much the
printing time should be or if it reaches threshold I will throw a error. We
already wrote a driver which involves SPI communication, motor rotation and
strobe(heating the paper) handling in driver, within the same driver I want
the temperature/ADC reading has to be done. 

Thanks and Regards,
Chandrasekhar

For your specific driver and device, or for "any" driver/device?

And why do you need this, what are you going to do with that
information?

thanks,
