Ok, will drop this in next version. > >> + regulator-always-on; > > Why are all these "always-on"?

I will recheck it once again and send a new version. thanks, srini > >> + }; >> + >> + }; >> + >> >> /* Temporary fixed regulator */ >> -- >> 1.9.1 >> -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
