1STMicroelectronics STi System Configuration Controlled IRQs
2-----------------------------------------------------------
3
4On STi based systems; External, CTI (Core Sight), PMU (Performance Management),
5and PL310 L2 Cache IRQs are controlled using System Configuration registers.
6This driver is used to unmask them prior to use.

8Required properties:
9- compatible	: Should be set to one of:
10			"st,stih415-irq-syscfg"
11			"st,stih416-irq-syscfg"
12			"st,stih407-irq-syscfg"
13			"st,stid127-irq-syscfg"
14- st,syscfg	: Phandle to Cortex-A9 IRQ system config registers
15- st,irq-device	: Array of IRQs to enable - should be 2 in length
16- st,fiq-device	: Array of FIQs to enable - should be 2 in length
17
18Optional properties:
19- st,invert-ext	: External IRQs can be inverted at will.  This property inverts
20		  these IRQs using bitwise logic.  A number of defines have been
21		  provided for convenience:
22			ST_IRQ_SYSCFG_EXT_1_INV
23			ST_IRQ_SYSCFG_EXT_2_INV
24			ST_IRQ_SYSCFG_EXT_3_INV
25Example:
26
27irq-syscfg {
28	compatible    = "st,stih416-irq-syscfg";
29	st,syscfg     = <&syscfg_cpu>;
30	st,irq-device = <ST_IRQ_SYSCFG_PMU_0>,
31			<ST_IRQ_SYSCFG_PMU_1>;
32	st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>,
33			<ST_IRQ_SYSCFG_DISABLED>;
34	st,invert-ext = <(ST_IRQ_SYSCFG_EXT_1_INV | ST_IRQ_SYSCFG_EXT_3_INV)>;
35};
