From 93301f5dbd72bd60882f88b4d04cafa3db4c85ed Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Mon, 26 Nov 2012 18:26:17 +0900 Subject: [PATCH] ARM: mach-shmobile: sh73a0: Initialise MMCIF using DT This device also requires a voltage regulator which should be defined in a board-specific maner. An example dts snipped follows. / { fixedregulator1v8: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "fixed-1.8V"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; }; }; &mmcif { vmmc-supply = <&fixedregulator1v8>; vqmmc-supply = <&fixedregulator1v8>; }; Signed-off-by: Simon Horman --- arch/arm/boot/dts/sh73a0-reference.dtsi | 24 ++++++++++++++++++++++++ arch/arm/mach-shmobile/clock-sh73a0.c | 1 + 2 files changed, 25 insertions(+) create mode 100644 arch/arm/boot/dts/sh73a0-reference.dtsi diff --git a/arch/arm/boot/dts/sh73a0-reference.dtsi b/arch/arm/boot/dts/sh73a0-reference.dtsi new file mode 100644 index 0000000..d4bb012 --- /dev/null +++ b/arch/arm/boot/dts/sh73a0-reference.dtsi @@ -0,0 +1,24 @@ +/* + * Device Tree Source for the SH73A0 SoC + * + * Copyright (C) 2012 Renesas Solutions Corp. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
