Subject: [PATCH v2 5/5] arm64: dts: rockchip: Specify override mode for kevin panel
Date: Wed, 7 Feb 2018 12:23:59 -0500 [thread overview]
Message-ID: <20180207172404.107358-6-seanpaul@chromium.org> (raw)
In-Reply-To: <20180207172404.107358-1-seanpaul-F7+t8E8rja9g9hUCZPvPmw@public.gmane.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.
Changes in v2:
- Wrap the timing in display-timings node to match binding (Rob/Thierry)
