Subject: [PATCH v4 3/7] arm64: dts: rockchip: Specify override mode for kevin panel
Date: Thu, 28 Mar 2019 10:17:06 -0700
Message-ID: <20190328171710.31949-4-dianders@chromium.org> (raw)
In-Reply-To: <20190328171710.31949-1-dianders@chromium.org>

From: Sean Paul <seanpaul@chromium.org>

This patch adds an override mode for kevin devices. The mode increases
both back porches to allow a pixel clock of 26666kHz as opposed to the
'typical' value of 252750kHz. This is needed to avoid interference with
the touch digitizer on these laptops.
