From f5bd51b60f4994023b5edd9241d2c0a839598553 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 11 Aug 2016 17:11:06 -0700 Subject: [PATCH] ARM: dts: imx7d: move CPU operating points to imx7d.dtsi Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX 7Solo can run with up to 800MHz and does so without making use of DVFS usually. While the device tree clearly specified a too fast operating point for i.MX 7Solo, the kernel did not used it in practise so far because the CPUfreq driver does not get loaded on i.MX 7Solo devices (since the fsl,imx7s compatible string is not in the list of devices making use of the cpufreq-dt driver...).
