Subject: [PATCH] arm64: dts: mediatek: mt8186: bpi-r3: Convert to sugar syntax
Overlay syntactic sugar for generating target-path fragments is
supported by the version of dtc supplied with the kernel since commit
50aafd60898a8b3e ("scripts/dtc: Update to upstream version
v1.4.6-21-g84e414b0b5bc"). Hence convert the Bananapi R3 overlay
devicetree source files to sugar syntax, improving readability.
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
