From a45011956d67f89f9434b6d73e65e41993375e69 Mon Sep 17 00:00:00 2001 From: Alexandre Torgue Date: Fri, 16 Feb 2018 18:11:52 +0100 Subject: [PATCH] ARM: dts: stm32: use dedicated files for pinctrl on stm32f7 family Currently, same stm32f746-pinctrl driver is used for stm32f746 and stm32f769 MCU. As pin map is different between those 2 MCUs, a stm32f769-pinctrl driver has been recently added. This patch -allows to use stm32f769-pinctrl driver for stm32f769 boards -reworks stm32 devicetree files to fit with stm32f746 / stm32f769 Signed-off-by: Alexandre Torgue --- arch/arm/boot/dts/stm32746g-eval.dts | 1 + arch/arm/boot/dts/stm32f7-pinctrl.dtsi | 227 +++++++++++++++++++++++++++++++ arch/arm/boot/dts/stm32f746-disco.dts | 1 + arch/arm/boot/dts/stm32f746-pinctrl.dtsi | 11 ++ arch/arm/boot/dts/stm32f746.dtsi | 217 ----------------------------- arch/arm/boot/dts/stm32f769-disco.dts | 3 +- arch/arm/boot/dts/stm32f769-pinctrl.dtsi | 11 ++ 7 files changed, 253 insertions(+), 218 deletions(-) create mode 100644 arch/arm/boot/dts/stm32f7-pinctrl.dtsi create mode 100644 arch/arm/boot/dts/stm32f746-pinctrl.dtsi create mode 100644 arch/arm/boot/dts/stm32f769-pinctrl.dtsi diff --git a/arch/arm/boot/dts/stm32746g-eval.dts b/arch/arm/boot/dts/stm32746g-eval.dts index 2d4e717..b2d4b8c 100644 --- a/arch/arm/boot/dts/stm32746g-eval.dts +++ b/arch/arm/boot/dts/stm32746g-eval.dts @@ -42,6 +42,7 @@ /dts-v1/;
