Drop this. It is already applied based on matching on the node name.

Drop minItems, as just 'maxItems: 1' is enough.

Just 'minItems: 2'.

Normally, for a compatible this would not vary...

In any case, move this to the main section and drop this if.

Just 'maxItems'

> +          maxItems: 2

These are redundant as 'items' size implies this.

Move this to the main section.

Is there a max number?

There's none in the original bindings document or enforced by the
driver.

I don't know how should this be constrained and the original bindings
document is not helpful.

-* Marvell MMP Interrupt controller
-
-Required properties:
-- compatible : Should be
-               "mrvl,mmp-intc" on Marvel MMP,
-               "mrvl,mmp2-intc" along with "mrvl,mmp2-mux-intc" on MMP2 or
-               "marvell,mmp3-intc" with "mrvl,mmp2-mux-intc" on MMP3
-- reg : Address and length of the register set of the interrupt controller.
-  If the interrupt controller is intc, address and length means the range
-  of the whole interrupt controller. The "marvell,mmp3-intc" controller
-  also has a secondary range for the second CPU core.  If the interrupt
-  controller is mux-intc, address and length means one register. Since
-  address of mux-intc is in the range of intc. mux-intc is secondary
-  interrupt controller.
-- reg-names : Name of the register set of the interrupt controller. It's
-  only required in mux-intc interrupt controller.
-- interrupts : Should be the port interrupt shared by mux interrupts. It's
-  only required in mux-intc interrupt controller.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source.
-- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
-  controller.
-- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
-  detection first.
-
-Example:
-	intc: interrupt-controller@d4282000 {
-		compatible = "mrvl,mmp2-intc";
-		interrupt-controller;
-		#interrupt-cells = <1>;
-		reg = <0xd4282000 0x1000>;
-		mrvl,intc-nr-irqs = <64>;
-	};
-
-	intcmux4@d4282150 {
-		compatible = "mrvl,mmp2-mux-intc";
-		interrupts = <4>;
-		interrupt-controller;
-		#interrupt-cells = <1>;
-		reg = <0x150 0x4>, <0x168 0x4>;
-		reg-names = "mux status", "mux mask";
-		mrvl,intc-nr-irqs = <2>;
-	};
-
-* Marvell Orion Interrupt controller
-
-Required properties
-- compatible :  Should be "marvell,orion-intc".
-- #interrupt-cells: Specifies the number of cells needed to encode an
-  interrupt source. Supported value is <1>.
-- interrupt-controller : Declare this node to be an interrupt controller.
-- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
-        One entry in the list represents 32 interrupts.
-
-Example:
-
-	intc: interrupt-controller {
-        	compatible = "marvell,orion-intc", "marvell,intc";
-		interrupt-controller;
-		#interrupt-cells = <1>;
-                reg = <0xfed20204 0x04>,
-		      <0xfed20214 0x04>;
-        };
