* ======== PRU INTC Map ========
*
* Define the INTC mapping for interrupts going to the ICSS / ICSSG:
* ICSS Host interrupts 0, 1
* ICSSG Host interrupts 0, 1, 10-19
*
* Note that INTC interrupts going to the ARM Linux host should not be defined
* in this file (ICSS/ICSSG Host interrupts 2-9).
*
* The INTC configuration for interrupts going to the ARM host should be defined
* in the device tree node of the client driver, "interrupts" property.
* See Documentation/devicetree/bindings/interrupt-controller/ti,pruss-intc.yaml
* entry #interrupt-cells for more.
*
* For example, on ICSSG:
*
* &client_driver0 {
* interrupt-parent = <&icssg0_intc>;
* interrupts = <21 2 2>, <22 3 3>;
* interrupt-names = "interrupt_name1", "interrupt_name2";
* };
*
