Subject: [PATCH 8/8] arm64: dts: salvator-x: Enable SCIF_CLK frequency and pins
Date: Thu, 4 Feb 2016 15:29:45 +0100 [thread overview]
Message-ID: <a3fc85e27b7e3c29b30909929bc64737a19fd251.1454595726.git.horms+renesas@verge.net.au> (raw)
In-Reply-To: <cover.1454595726.git.horms+renesas@verge.net.au>
From: Geert Uytterhoeven <geert+renesas@glider.be>
Add and enable the external crystal for the SCIF_CLK and its pinctrl, to
be used by the Baud Rate Generator for External Clock (BRG) on (H)SCIF.
This increases the range and accuracy of supported baud rates:
- SCIF:
- Supports now 50, 230400, 460800, 500000, and 921600 bps,
- Perfect match for standard 50-460800, and 9216000 bps.
- HSCIF:
- Supports now 50, 75, and 110 bps,
- Perfect match for standard 50-460800, and 9216000 bps.
