This SiP module integrates the SoC, DDR Memory, PMIC, EEPROM etc. https://octavosystems.com/octavo_products/osd32mp15x/ Signed-off-by: Sean Nyekjaer --- This is made with great inspiration from Neeraj Dantu's work: https://raw.githubusercontent.com/octavosystems/OSD32MP1-RED-Device-tree/main/linux-v5.10-r0/stm32mp157c-osd32mp1-red.dts So what copyright is needed here? And author? Still need to test ethernet and HDMI, thats why I have done this a RFC. Is it good pratice to add labels to all regulator's on the PMIC so boards can add regulator options? arch/arm/boot/dts/stm32mp15xx-osd32mp1.dtsi | 308 ++++++++++++++++++++ 1 file changed, 308 insertions(+) create mode 100644 arch/arm/boot/dts/stm32mp15xx-osd32mp1.dtsi diff --git a/arch/arm/boot/dts/stm32mp15xx-osd32mp1.dtsi b/arch/arm/boot/dts/stm32mp15xx-osd32mp1.dtsi new file mode 100644 index 000000000000..4de9213f6d43 --- /dev/null +++ b/arch/arm/boot/dts/stm32mp15xx-osd32mp1.dtsi @@ -0,0 +1,308 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR BSD-3-Clause) +/* + * Copyright (C) ?? - All Rights Reserved + * Author: ??? + */ + +#include "stm32mp15-pinctrl.dtsi" +#include "stm32mp15xxac-pinctrl.dtsi" +#include +#include +#include + +/ { + reserved-memory { + #address-cells = <1>;
