From f5d35d87ef061172a25252b2b5402c972b16d3be Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 11 Mar 2020 17:02:06 +0800 Subject: [PATCH] ARM: dts: imx: add nvmem property for cpu0 Add nvmem related property for cpu0, then nvmem API could be used to read cpu speed grading to avoid directly read OCOTP registers mapped which could not handle defer probe.
