IMX6UL ADC confusing register addresses used in Linux source code

Question asked by Ameer Hamza on Oct 6, 2016

Hi all,

 

I've got a question regarding imx6ul adc controller register set. In following link Linux/drivers/input/touchscreen/imx6ul_tsc.c - Linux Cross Reference - Free Electrons  The register offsets defined from line number 42 to line number 49 are different as compared to the register offsets described in Reference Manual provided by NXP. I have to develop a touchscreen but its sort of confusing like in touch screen documentation it is mention that ADC_HC3 should be configure to channel 1 or 2 but ADC_HC3 is not exist in the ADC register set. Any help would be appreciated.

 

Thanks,

am hamza.
