Felipe's 'next' is closed for 3.10, so this series won't be making it to 3.10 now, as a whole. :-( > > http://marc.info/?l=linux-usb&m=136057666911621&w=2 > > Does this patchset build on top of that? Yea, it builds fine on top of the above mentioned patch. I would suggest that we pull the xhci-plat patch in this series when the complete patch-set getting in. btw, its your decision ;-) > > I'm really behind on my patches for 3.10, sorry. > > Sarah Sharp > > On Mon, Apr 01, 2013 at 07:23:59PM +0530, Vivek Gautam wrote: >> This patch-series enables runtime power management on xhci-plat, >> dwc3-core, dwc3-exynos as well as on Samsung's USB 2.0 type and >> USB 3.0 type PHYs. >> >> Based on 'next' branch of Felipe Balbi's USB tree. >> >> Changes from v2: >> - Using separate functions for USB PHY runtime power management, instead of >> using macros. >> - Adding 'pm_runtime_set_suspended()' api call in dwc3 core layer before >> enabling runtime pm.
