From 7f668a6fbecdabf9ba84f7d205ba9b882c450aa5 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Fri, 20 Jan 2017 14:03:52 +0100 Subject: [PATCH] arm: omap3: Update cpuinfo for DM3730, DM3725, AM3715, and AM3703 The check for OMAP3630/3730 only checks for 800MHz 3630/3730, but anything else is lumped into 36XX/37XX with an assumed 1GHz speed. Based on the DM3730 TRM bit 9 shows the MPU Frequency (800MHz/1GHZ). This also adds the ability to distinguish between the DM3730, DM3725, AM3715, and AM3703 and correctly display their maximum speed.
