Kernel Exception: irq 64: nobody cared

[thom_nic]

We are using the stmp157-som-512-ext and I see this exception in dmesg soon after boot.  It appears to possibly be related to the axp209?  We are compiling the kernel and using our own DTS however it is very similar to the Olimex defconfig and dts (mostly disabling unused peripherals such as sound and display, etc.)  What driver is using interrupt 64?
