The approach with the disabled controllers in board DTS files (for our
boards) is to use the: status = "disabled" and if there are pin conflicts
with other controllers to put a mark in there, something like:
				status = "disabled"; /* Conflict with X */

I'm seeing that i2s1 is in conflict with sdmmc1 and spi0.

Thank you,

Ok, I will disable them and add the pin conflicts in the next version. 
Thank you for your review.
