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. 7 8Required properties: 9- compatible : Should be "st,stih407-irq-syscfg" 10- st,syscfg : Phandle to Cortex-A9 IRQ system config registers 11- st,irq-device : Array of IRQs to enable - should be 2 in length 12- st,fiq-device : Array of FIQs to enable - should be 2 in length 13 14Optional properties: 15- st,invert-ext : External IRQs can be inverted at will. This property inverts 16 these IRQs using bitwise logic. A number of defines have been 17 provided for convenience: 18 ST_IRQ_SYSCFG_EXT_1_INV 19 ST_IRQ_SYSCFG_EXT_2_INV 20 ST_IRQ_SYSCFG_EXT_3_INV 21Example: 22 23irq-syscfg { 24 compatible = "st,stih407-irq-syscfg"; 25 st,syscfg = <&syscfg_cpu>; 26 st,irq-device = <ST_IRQ_SYSCFG_PMU_0>, 27 <ST_IRQ_SYSCFG_PMU_1>; 28 st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>, 29 <ST_IRQ_SYSCFG_DISABLED>; 30}; 31
