The important part is where it could change > behavior for OLPC and it migh end up without a RTC. I Cc Andres > Salomon as might know where the RTC on OLPC is comming from. The RTC that OLPC uses for XO-1 was interspersed w/ the power management stuff, so it hasn't gone upstream yet (dsd is still working on the pm stuff). Thus, for Linus kernels the XO-1 uses rtc_cmos; so yes, this could break things. On OLPC kernels on the XO-1, we read RTC information from the CS5536's MSRs (note that there's nothing there that's OLPC-specific, so this should probably become a generic geode RTC driver). I'm unfamiliar with the XO-1.5, but it appears we use the VX855 RTC (at least for wakeups). I don't see a specific RTC driver for it, so I suspect it relies on rtc_cmos. > > >gone in via the tip tree, so it would be useful to regroup and figure > >out which ones are no longer needed. > I try to regroup and a add TIP or OF prefix. > > >I'll be able to take a fresh look and pick up the ones that are ready > >after the merge window closes. > Okay. > > >Thanks, > >g. > > [0] https://patchwork.kernel.org/patch/450681/ > > Sebastian
