From 01aabf97d1f08694ed511785638685cbee21e597 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Tue, 19 Feb 2019 00:37:20 +0100 Subject: [PATCH] ARM: dts: stm32: Migrate U-boot nodes to U-boot DT files for stm32f7 In order to prepare and ease future DT synchronization with kernel DT, migrate all U-boot specific nodes/properties/addons to U-boot DT files. Migrate also DT nodes which are not yet available on kernel DT side as ethernet, ltdc and qspi nodes. Fix ethernet_mii pins and add missing qspi_pins for stm32746g-eval Signed-off-by: Patrice Chotard --- arch/arm/dts/stm32746g-eval-u-boot.dtsi | 171 +++++++++++++++ arch/arm/dts/stm32746g-eval.dts | 142 +------------ arch/arm/dts/stm32f7-u-boot.dtsi | 143 +++++++++++-- arch/arm/dts/stm32f746-disco-u-boot.dtsi | 251 +++++++++++++++++++++++ arch/arm/dts/stm32f746-disco.dts | 217 -------------------- arch/arm/dts/stm32f746.dtsi | 60 +----- arch/arm/dts/stm32f769-disco-u-boot.dtsi | 165 +++++++++++++++ arch/arm/dts/stm32f769-disco.dts | 167 --------------- 8 files changed, 718 insertions(+), 598 deletions(-) create mode 100644 arch/arm/dts/stm32746g-eval-u-boot.dtsi create mode 100644 arch/arm/dts/stm32f746-disco-u-boot.dtsi create mode 100644 arch/arm/dts/stm32f769-disco-u-boot.dtsi diff --git a/arch/arm/dts/stm32746g-eval-u-boot.dtsi b/arch/arm/dts/stm32746g-eval-u-boot.dtsi new file mode 100644 index 0000000000..27d3c8a445 --- /dev/null +++ b/arch/arm/dts/stm32746g-eval-u-boot.dtsi @@ -0,0 +1,171 @@ +// SPDX-License-Identifier: GPL-2.0+ + +#include +/{ + chosen { + bootargs = "root=/dev/mmcblk0p1 rw rootwait";
