[PATCH v3 4/5] arm64: dts: exynosautov9: prepare usi0 changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Before adding whole USI nodes, this applies the changes of usi0 in
advance. To be the usi0 and serian_0 nodes as SoC default, some
properties should be moved to exynosautov9-sadk.dts.
