Subject: [PATCH V2 1/2] arm64: dts: imx8mm: Correct OPP table according to latest datasheet
Date:   Sat, 29 Jun 2019 18:21:56 +0800
Message-Id: <20190629102157.8026-1-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Anson Huang <Anson.Huang@nxp.com>

According to latest datasheet (Rev.0.2, 04/2019) from below links,
1.8GHz is ONLY available for consumer part, so the market segment
bits for 1.8GHz opp should ONLY available for consumer part accordingly.
