From 35dc29ef0f5de174537ddeb0f202adb8e99e2ea6 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Mon, 8 Apr 2019 07:44:21 +0000 Subject: [PATCH] ARM: dts: imx6dl-sabreauto: update opp table for auto part Update i.MX6DL automotive part's opp table according to i.MX6DL automotive datasheet Rev.9, 11/2018, it adds 996MHz set-point support as below: LDO enabled(min value): 996MHz: VDDARM: 1.275V, VDDSOC: 1.175V; 792MHz: VDDARM: 1.150V, VDDSOC: 1.150V; 396MHz: VDDARM: 1.125V, VDDSOC: 1.150V; Adding 25mV to cover board IR drop, for LDO enabled mode of 996MHz, as the max value of LDO output can NOT exceed 1.3V, so 25mV is NOT added for VDDARM.
