From bcc4f4e118e46ba86a8ddd448d318c5bd8fada5d Mon Sep 17 00:00:00 2001 From: Ludovic Barre Date: Mon, 26 Feb 2018 16:49:18 +0100 Subject: ARM: dts: stm32: add initial support of stm32mp157c eval board Add support of stm32mp157c evaluation board (part number: STM32MP157C-EV1) split in 2 elements: -Daughter board (part number: STM32MP157C-ED1) which includes CPU, memory and power supply -Mother board (part number: STM32MP157C-EM1) which includes external peripherals (like display, camera,...) and extension connectors. The daughter board can run alone, this is why the device tree files are split in two layers, for the complete evaluation board (ev1) and for the daughter board alone (ed1).
