From afca68de401fceb1d52e1b6daec78e8b09f7f0a2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 4 Apr 2022 11:28:06 +0100 Subject: [PATCH] ARM: dts: at91: Describe regulators on at91sam9g20ek The at91sam9g20ek has no software controllable regulators, only some fixed discrete regulators, but they are there and currently the wm8731 driver does try to use them. Show the supplies in the DT and map them for the wm8731 so things start up cleanly.
