[Linux-stm32] [PATCH 11/12] ARM: dts: stm32: Split Avenger96 into DHCOR SoM and Avenger96 board
Marek Vasut
marex at denx.de
Wed Apr 29 16:37:42 UTC 2020
The Avenger96 is in fact an assembly of DH Electronics DHCOR SoM on top
of an Avenger96 reference board. Split the DTs to reflect that and make
sure to DHCOR SoM can be reused on other boards easily.
