Can you point me to where I can get the register definition files for the MCIMX6XxE (imx6sx) and MCIMX6SxD (dualLite)? They will be like the attached one (for the Vybrid) except for the iMX6 processors mentioned above. I assume they're in the Linux BSPs somewhere, but I don't know what the file names or directories are.
You can follow the i.MX Reference manual of the linux version that you are using. It will have the information regarding the files that you are looking for. Moreover, you can also have a look at i.MX Reference manual for particular board for more registers information. Below is the screenshot of the i.MX Reference Manual for linux version L4.14.98:
