From: Reinhold Mueller <reinhold.mueller@xxxxxxxxxx> This patch adds support for the emtrion GmbH Argon board series. They are available with STM32MP157 from STMicroelectronics with 512 MByte Memory. The devicetree stm32mp157c-emstamp-argon.dtsi is the common part providing the module components and the basic support for the SoC. The support for the emSBC-Argon baseboard in the developer-kit configuration is provided by the stm32mp157c-emsbc-argon.dts file.
