Changes in v2:
- Added Conor's r-by
- Removed quotes surrounding $refs
- Hardcoded 'st,invert-ext' possible values
Changes in v3:
- Fixed enum syntax warnings
- Removed reference to driver in favor of device
Changes in v4:
- Make clearer description for "st,invert-ext" property
- Handle better bitwise logic

-STMicroelectronics STi System Configuration Controlled IRQs
------------------------------------------------------------
-
-On STi based systems; External, CTI (Core Sight), PMU (Performance Management),
-and PL310 L2 Cache IRQs are controlled using System Configuration registers.
-This driver is used to unmask them prior to use.
-
-Required properties:
-- compatible : Should be "st,stih407-irq-syscfg"
-- st,syscfg : Phandle to Cortex-A9 IRQ system config registers
-- st,irq-device : Array of IRQs to enable - should be 2 in length
-- st,fiq-device : Array of FIQs to enable - should be 2 in length
-
-Optional properties:
-- st,invert-ext : External IRQs can be inverted at will. This property inverts
- these IRQs using bitwise logic. A number of defines have been
- provided for convenience:
- ST_IRQ_SYSCFG_EXT_1_INV
- ST_IRQ_SYSCFG_EXT_2_INV
- ST_IRQ_SYSCFG_EXT_3_INV
-Example:
-
-irq-syscfg {
- compatible = "st,stih407-irq-syscfg";
- st,syscfg = <&syscfg_cpu>;
- st,irq-device = <ST_IRQ_SYSCFG_PMU_0>,
- <ST_IRQ_SYSCFG_PMU_1>;
- st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>,
- <ST_IRQ_SYSCFG_DISABLED>;
-};
