i.MX6SX PMIC Interrupt

Hi all,

    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,

Regards

Balaji.V

Hi Balaji

there is no problem with moving it to another gpio, in linux/uboot sources it is not

used, seems it is just reserved for future use.

Best regards

Can I leave it unconnected (Or with just a PU resistor), if I am using the current BSP?
