+* ARM Vectored Interrupt Controller
+
+One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM
+system for interrupt routing.  For multiple controllers they can either be
+nested or have the outputs wire-OR'd together.
+
+Required properties:
+
+- compatible : should be one of
+        "arm,pl190-vic"
+        "arm,pl192-vic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : The number of cells to define the interrupts.  Must be 1 as
+  the VIC has no configuration options for interrupt sources.  The cell is a u32
+  and defines the interrupt number.
+- reg : The register bank for the VIC.
+
+Optional properties:
+
+- interrupts : Interrupt source for parent controllers if the VIC is nested.
+
+Example:
+
+        vic0: interrupt-controller@60000 {
+                compatible = "arm,pl192-vic";
+                interrupt-controller;
+                #interrupt-cells = <1>;
+                reg = <0x60000 0x1000>;
+        };

+          If a data is stalled inside asynchronous bridge because of back
+          pressure, it may be accepted multiple times, creating pointer
+          misalignment that will corrupt next transfers on that data path
+          until next reset of the system (No recovery procedure once the
+          issue is hit, the path remains consistently broken). Async bridge
+          can be found on path between MPU to EMIF and MPU to L3 interconnect.
+          This situation can happen only when the idle is initiated by a
+          Master Request Disconnection (which is trigged by software when
+          executing WFI on CPU).
+          The work-around for this errata needs all the initiators connected
+          through async bridge must ensure that data path is properly drained
+          before issuing WFI. This condition will be met if one Strongly ordered
+          access is performed to the target right before executing the WFI.
+          In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained.
+          IO barrier ensure that there is no synchronisation loss on initiators
+          operating on both interconnect port simultaneously.

+ *      3 - CPUx L1 and logic lost + GIC + L2 lost: MPUSS OFF
+ * @return: This function never returns for CPU OFF and DORMANT power states.
+ * Post WFI, CPU transitions to DORMANT or OFF power state and on wake-up
+ * from this follows a full CPU reset path via ROM code to CPU restore code.
+ * The restore function pointer is stored at CPUx_WAKEUP_NS_PA_ADDR_OFFSET.
+ * It returns to the caller for CPU INACTIVE and ON power states or in case
+ * CPU failed to transition to targeted OFF/DORMANT state.
