From 322bf103204b8f786547acbeed85569254e7088f Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 4 Aug 2023 18:08:54 +0100 Subject: [PATCH] arm64: dts: allwinner: h616: Split Orange Pi Zero 2 DT The Orange Pi Zero 2 got a successor (Zero 3), which shares quite some DT nodes with the Zero 2, but comes with a different PMIC. Move the common parts (except the PMIC) into a new shared file, and include that from the existing board .dts file. No functional change, the generated DTB is the same, except for some phandle numbering differences.
