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>; }; |
