I am planning to use the same PMIC (F6 Version), that is used in i.MX6SX-SDB, in my custom i.MX6SX board. While reviewing the schematic of the SDB more closely, I observed the PMIC_INT signal is connected to E16 pin of the i.MX6SX. I have the following queries in this regard:
a. Is it configured in the Linux Kernel or is it configured in the U-Boot or is it configured in DTS file, if so which file?
b. Can I use a different GPIO for this purpose (in case if it is configured as a GPIO Input)?
Any pointers/references will be much appreciated,
