It isn't clear to me why these should be made optional, I hope Rob provides some clarification in the sdhci-msm thread. > > + > > +Option properties: Woops, this should be "Optional" :). > > +- linux,allow-set-time: indicates that the setting of RTC time is allowed by > > + the host CPU > > Is this a "linux" property?
