From eaba7df7041ebdd6cff3702d87d6bdb6870ec5e3 Mon Sep 17 00:00:00 2001 From: Hannes Schmelzer Date: Wed, 6 Feb 2019 13:25:59 +0100 Subject: board/BuR/brxre1: convert do DM This commit converts the brxre1 board to DM, for this we have todo following things: - add a devicetree-file for this board - drop all obsolete settings from board header-file - use dm_i2c_xxx calls for read/write to the resetcontroller - request gpios before operate them Serues-cc: trini@konsulko.com Signed-off-by: Hannes Schmelzer --- arch/arm/dts/am335x-brxre1.dts | 371 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 371 insertions(+) create mode 100644 arch/arm/dts/am335x-brxre1.dts (limited to 'arch/arm/dts/am335x-brxre1.dts') diff --git a/arch/arm/dts/am335x-brxre1.dts b/arch/arm/dts/am335x-brxre1.dts new file mode 100644 index 00000000000..708407daf2e --- /dev/null +++ b/arch/arm/dts/am335x-brxre1.dts @@ -0,0 +1,371 @@ +// SPDX-License-Identifier: GPL-2.0+ +/* + * Copyright (C) 2019 B&R Industrial Automation GmbH + * http://www.br-automation.com + * + */ +/dts-v1/;
