Subject: [PATCH v4 3/9] ARM: dts: gose: Enable SCIF_CLK frequency and pins
Date: Fri, 29 Jan 2016 11:17:20 +0100	[thread overview]
Message-ID: <1454062646-4826-4-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1454062646-4826-1-git-send-email-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.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
Untested, based on (non)differences in U-Boot sources between koelsch
and gose.

v4:
  - Change one-line summary prefix to match current arm-soc practices,

v3:
  - New.
