[PATCH V2 5/6] ARM: dts: stm32: Rework DDR DT inclusion
Marek Vasut

Fri Apr 10 20:55:49 CEST 2020
Adjust the DDR configuration dtsi such that they only generate the
DRAM configuration node, the DDR controller node is moved into the
stm32mp157-u-boot.dtsi itself. This permits including multiple DDR
configuration dtsi files in board DT.
