Subject: [PATCH v4 9/9] arm64: dts: salvator-x: Enable SCIF_CLK frequency and pins
Date: Fri, 29 Jan 2016 11:17:26 +0100 [thread overview]
Message-ID: <1454062646-4826-10-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1454062646-4826-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>
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.
