From 37eadb8555c09395e7dd2b6af83ff82ff9a1e990 Mon Sep 17 00:00:00 2001 From: Alexandre Torgue Date: Tue, 5 Feb 2019 10:07:00 +0100 Subject: ARM: dts: stm32: add initial support of stm32mp157a-dk1 board Add support of stm32mp157a discovery1 board (part number: STM32MP157A-DK1). This board embeds a STM32MP157a SOC with AC package (TFBGA361, 148 ios) and 512MB of DDR3. Several connections are available on this boards: 4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ... This patch enables basic support for a kernel boot.

The STPMIC1 is a PMIC from STMicroelectronics. The STPMIC1 integrates 10 regulators, 3 power switches, a watchdog and an input for a power on key. The DMAs are disabled because the PMIC generates a very few traffic and DMA channels may lack for other usage.
