Subject: [PATCH 2/2] arm64: dts: imx8mm: Correct OPP table according to latest datasheet
Date: Fri, 28 Jun 2019 11:28:00 +0800 [thread overview]
Message-ID: <20190628032800.8428-2-Anson.Huang@nxp.com> (raw)
In-Reply-To: <20190628032800.8428-1-Anson.Huang@nxp.com>
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.
