Hi Michal,

Thank you for the patch.

This should read

				interrupts = <GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>,
					     <GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>,
					     <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;

The issue isn't introduced by this patch, so it should probably be fixed
by a separate patch on top, to convert the whole zynqmp.dtsi file. Do
you have any plan to do so, or should I ?
