From: Marek Vasut Date: Wed, 13 May 2020 18:10:20 +0000 (+0200) Subject: ARM: dts: stm32: Split Avenger96 into DHCOR SoM and Avenger96 board X-Git-Tag: v5.10.7~2441^2~43^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7e76f82acd9e12fe7765d5d8c200b37787c994e4;p=platform%2Fkernel%2Flinux-rpi.git ARM: dts: stm32: Split Avenger96 into DHCOR SoM and Avenger96 board The Avenger96 is in fact an assembly of DH Electronics DHCOR SoM on top of an Avenger96 reference board. The DHCOR SoM can be populated with any STM32MP15xx. Split the DTs to reflect this such that the common SoM and Avenger96 parts are now in stm32mp15xx-dhcor-*dtsi and a specific example implementation of STM32MP157A SoM and Avenger96 board is separated into stm32mp157a-dhcor-*dts* . The stm32mp157a-avenger96.dts is retained for the sake of backward naming compatibility.
