Subject: [PATCH v3 6/6] arm64: dts: rockchip: Specify override mode for kevin panel
Date: Thu, 8 Feb 2018 12:48:53 -0500 [thread overview]
Message-ID: <20180208174855.55620-7-seanpaul@chromium.org> (raw)
In-Reply-To: <20180208174855.55620-1-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.
Changes in v2:
- Wrap the timing in display-timings node to match binding (Rob/Thierry)
Changes in v3:
- Unwrap the timing from display-timings and rename panel-timing (Rob)
