From 5059791efc73a628fcda8d0dec79d98a8a66c454 Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Fri, 15 Nov 2019 11:08:54 +0100 Subject: dt-bindings: rng: Convert stm32 RNG bindings to json-schema Convert the STM32 RNG binding to DT schema format using json-schema Remove interrupt from the json-schema because it is not used by the driver.
