Hello,
A new PM branch is available named pm-20081119.
This is mostly a new set of patches on top of the previous PM branch,
rather than a rebase. We finally found the root cause of some DPLL
relocking bugs. Special thanks to Paul Walmsley and Tero Kristo for
debugging and fixing this problem. Now the DPLL fix that was reverted
in the previous PM branch is re-applied as well as some fixes on top
of it. It also has some additional UART fixes, so I think the UART
idle work is ready to go to Tony. Special thanks to Jouni Hogander
for the extra testing and fixes here.
The shortlog is below[1] and the root of the tree is still
v2.6.27-omap1 + T2 power patches from Peter.
This has primarily been tested on custom HW since I'm _still_ waiting
for my SDP to arrive. I have boot tested on Beagle, but I think there
are still some problems with ES2 silicon. On my ES2 Beagle, neither
DSS or IVA will leave the ON state, even when all clocks in their
powerdomains are off. I have not debugged this further yet.
Functionally, this tree is in pretty good shape, so I will do some
bugfixes here when necessary, but will now spent some time focusing on
getting the patches in this branch merged into linux-omap.
Kevin
