Looks good to me:

Reviewed-by: Ezequiel Garcia <ezequiel@collabora.com>

And it made me think, how many of these do we have?
Or even worse, how many are using the wrong specifiers?

$ git grep interrupts -- arch/arm/boot/dts  | grep -v IRQ_TYPE | grep GPIO
arch/arm/boot/dts/am335x-baltos-ir3220.dts:		interrupts = <20 GPIO_ACTIVE_LOW>;
arch/arm/boot/dts/am335x-baltos-ir5221.dts:		interrupts = <20 GPIO_ACTIVE_LOW>;
arch/arm/boot/dts/am335x-baltos.dtsi:		interrupts = <28 GPIO_ACTIVE_LOW>;
arch/arm/boot/dts/am335x-boneblue.dts:		interrupts = <21 GPIO_ACTIVE_LOW>;
arch/arm/boot/dts/at91-sama5d2_xplained.dts:						interrupts = <PIN_PB13
GPIO_ACTIVE_LOW>;
arch/arm/boot/dts/imx53-qsb.dts:		interrupts = <11 0x8>; /* low-level active IRQ at GPIO7_11 */
arch/arm/boot/dts/imx53-voipac-dmm-668.dtsi:		interrupts = <11 0x8>; /* low-level active IRQ at GPIO7_11
