[PATCH] dt-bindings: i2c: st,stm32-i2c: Document interrupt-names property

[Marek Vasut]

Document interrupt-names property with "event" and "error" interrupt names.
This fixes dtbs_check warnings when building current Linux DTs:

"
arch/arm/boot/dts/stm32mp153c-dhcom-drc02.dtb: i2c at 40015000: Unevaluated properties are not allowed ('interrupt-names' was unexpected)
"
