-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>;

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230805144646.33819-1-rgallaispou@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
