From 6a7548305a04ae0cd9e9f062c050f265d4bf2d2e Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 24 Sep 2020 10:26:42 +0200 Subject: ARM: dts: bcm2835: Change firmware compatible from simple-bus to simple-mfd The current binding for the RPi firmware uses the simple-bus compatible as a fallback to benefit from its automatic probing of child nodes. However, simple-bus also comes with some constraints, like having the ranges, our case. Let's switch to simple-mfd that provides the same probing logic without those constraints.
