As the description says, this property contains a pair of calibration values. The number of items must be exactly 2. Add minItems to check a too short property. While I was here, I also added this property to the example because this is the case in the real DT file, arch/arm64/boot/dts/socionext/uniphier-ld20.dtsi Also, fix the interrupt type (edge -> level) to align with the real DT.
