1 PDC interrupt controller
4 Power Domain Controller (PDC) that is on always-on domain. In addition to
10 controller PDC is next in hierarchy, followed by others. Drivers requiring
11 wakeup capabilities of their device interrupts routed through the PDC, must
12 specify PDC as their interrupt controller and request the PDC port associated
20 	Definition: Should contain "qcom,<soc>-pdc" and "qcom,pdc"
21 		    - "qcom,sc7180-pdc": For SC7180
22 		    - "qcom,sdm845-pdc": For SDM845
27 	Definition: Specifies the base physical address for PDC hardware.
28 		    Optionally, specify the PDC's GIC interface registers that
30 		    the PDC.
38 		    The first element of the tuple is the PDC pin for the
47 - qcom,pdc-ranges:
50 	Definition: Specifies the PDC pin offset and the number of PDC ports.
51 		    The tuples indicates the valid mapping of valid PDC ports
53 		    The first element of the tuple is the starting PDC port.
54 		    The second element is the GIC hwirq number for the PDC port.

67 		compatible = "qcom,sdm845-pdc";
69 		qcom,pdc-ranges = <0 512 94>, <94 641 15>, <115 662 7>;
80 		interrupts-extended = <&pdc 2 IRQ_TYPE_LEVEL_HIGH>;
83 In this case interrupt 514 would be mapped to port 2 on the PDC as defined by
84 the qcom,pdc-ranges property.
