SDP, omap3evm, Beagle and RX51 are all good example. But for PM, the board files only come into play for DVFS, where the board files can configure which OPPs to make available to core code. On the current PM branch, I did not test DVFS on Overo because it seems like the SDRC settings need some testing/updating[1]. > At the moment, if I look at the linux-omap-2.6 repository and take a > look at omap-2.6.30 branch, and take a look at board-overo.c, I don't > find any entries for including omap-pm.h, etc. That's because that branch has no PM support. > You had mentioned that there was initial support for overo in the > omap-2.6.30 release, so I thought I'd just start and check there > initially. No, I mentioned[1] that there was basic Overo testing done on the latest 'pm' branch, not omap-2.6.30 branch. Please checkout the branch named 'pm' and look there. You still will not see omap-pm.h included because I did not test DVFS on Overo since just going idle eventually leads to memory corruption. As I stated[1], SDRC settings need some validation on Overo before DVFS can be tested. Kevin [1] http://www.mail-archive.com/linux-omap@vger.kernel.org/msg13980.html
