From cae878d2eb134423fc58edfbb698e5cb18db6e20 Mon Sep 17 00:00:00 2001 From: Bai Ping Date: Tue, 13 Jan 2015 22:19:53 +0800 Subject: [PATCH] MLK-10089 arm: imx: Add 198MHz OPP for i.MX6SX Update the i.MX6SX operating points to comply with the latest datasheet. Latest i.MX6SX datasheet of Rev.F, 1/2015 adds the 198MHz setpoint. For the RevB board, the VDD_ARM and ADD_SOC are connected together, so the voltage for 198MHz needs to be set to 1.175V. for the general setting, add a 25mV margin to cover the board IR drop.
