[PATCH 4/4] sunxi: dts: arm: update devicetree files from Linux kernel tree
Andre Przywara
andre.przywara at arm.com
Sun Oct 26 02:23:56 CET 2025
Sync the kernel devicetree source files for the Allwinner SoCs with
32-bit cores that do not use OF_UPSTREAM yet. The files were taken
from a v6.18-rc1 tree.
To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.
This commit also adds a new board devicetree for the A33 Vstar board,
plus one DT overlay for the OrangePi Zero interface board.
This update should not impact any existing U-Boot functionality.
