From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Geert Uytterhoeven To: Simon Horman , Magnus Damm Cc: linux-renesas-soc@vger.kernel.org, linux-arm-kernel@lists.infradead.org, devicetree@vger.kernel.org, Geert Uytterhoeven Subject: [PATCH v4 9/9] arm64: dts: salvator-x: Enable SCIF_CLK frequency and pins Date: Fri, 29 Jan 2016 11:17:26 +0100 Message-Id: <1454062646-4826-10-git-send-email-geert+renesas@glider.be> In-Reply-To: <1454062646-4826-1-git-send-email-geert+renesas@glider.be> References: <1454062646-4826-1-git-send-email-geert+renesas@glider.be> Sender: devicetree-owner@vger.kernel.org List-ID: 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.
