Re: [PATCH] ARM: dts: msm8974-FP2: add reboot-mode node

Hi Brian,
how about something like that (formatting is surely broken because I'm not
sending this with git-send-email^^)?

I'd says this should be work fine with all devices as all modes are defined in
the device-specific dts but the reg and offset values are in the board dts.
Should I also add a status = "disabled" to the reboot-mode node in the board
dts?
