+description: |
+  Qualcomm Technologies Inc. SoCs can be interrupted in order to come out
+  of low power modes, knowing the wake up source allows debugging of
+  unnecessary wake up interrupts that may bring the SoC out of its low power
+  mode. Driver reads GIC registers to determine the interrupt which triggered
+  just before the resume loop unrolls.
