ARM: dts: exynos: Properly override node to use MDMA0 on Universal C210 (0fd5ff9e) · Commits · 戴 / test

The Universal C210 (Exynos4210) uses the secure interface of MDMA0, instead of regular one - non-secure MDMA1. DTS was overriding MDMA1 node address which caused DTC W=1 warning: arch/arm/boot/dts/exynos4.dtsi:707.25-716.6: Warning (simple_bus_reg): /soc/amba/mdma@12850000: simple-bus unit address format error, expected "12840000" Signed-off-by:
