[PATCH 33/34] sunxi: A523: add DT files from Linux v3 branch
Andre Przywara
andre.przywara at arm.com
Sun Mar 23 12:35:43 CET 2025
This imports the (preliminary) devicetree files for the boards with the
new Allwinner A523/T527/H728 SoCs, including the basic SoC .dtsi.
Those files have been reviewed and confirmed, but have not been merged
into the official kernel repositories yet.
Pending upstream kernel repository:
