The latest pm branch does seem to work fine on my SDP after taking in Jouni's patch "[PATCH PM-20081106] OMAP3: UART: Make sure that uart clocks are enabled when needed" and restricting the enabled_uarts to debug console. I however did not see the VCORE led blink while hitting OFF. regards, Rajendra > > [1] 2ac1da8c787f73f067e717408e631501ba60aabc > > >> -----Original Message----- > >> From: linux-omap-owner@xxxxxxxxxxxxxxx > >> [mailto:linux-omap-owner@xxxxxxxxxxxxxxx] On Behalf Of Kevin Hilman > >> Sent: Friday, November 07, 2008 11:00 PM > >> To: linux-omap@xxxxxxxxxxxxxxx > >> Subject: new PM branch: pm-20081106 > >> > >> For those who want to experiment with the latest PM > branch, it is now > >> available in OMAP git as branch pm-20081106 > >> > >> The shortlog is below[1], but the significant thing for now is a > >> rework of how UART handles its clocks and allows idle.
