WSOD will need redisign (and spec)

Hi All,

it seems that my last effort to get sleep states to work properly on the
LCM driver brought back an old cold temperature WSOD issue.

As of my last rework, I figure-out that Harald's original design of
having two independent state machines for JBT and Glamo was wrong. My
last patch was trying to use the Framebuffer Events to link the two
drivers but I quickly realized that the real solution would be to get
the Glamo driver notify the LCM through a generalized LCM interface
(this is partially existing). We often have to wait for a period of two
frames after certain operation on the JBT before doing other operation
on the Glamo and vis-versa.

I'm ready to work keep working on that, it I have little hope into
getting it fixed totally without spec. That's why I'm asking if there is
a way I can obtain the NDA protected JBT spec from OpenMoko (I mean
legal way) ?

Hoping that can be done,
