NAK. SoC dtsi nodes are enabled by default, the actual "disable" in a node only makes sense if that node has some dependency on board specific physical dts property - such as pinmux etc that characterizes. This is the discussion we have had and why selective muxes are enabled. CPU cores make no sense to disable by default - you could have a case where they may be efused out on a sub device variant, in which case, you are perfectly valid to disable that node in the board dts OR if the sub device variant is used on multiple boards, introduce a sub board variant and disable it in the dtsi. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
