[PATCH 0/6] GTA02 frequency scaling on 2.6.29

Waiting for the new 2.6.3x openmoko kernel, these series of patches
add some frequency scaling to the andy-tracking kernel, hope that they
apply because they are based on my private kernel version. BTW.

How to use them:

config the PERFORMANCE governator during bootup, when the system is "up"
set the cpuinfo_min_freq to 100000 because the pheripheral doesn't support
lower frequency and the use the ondemand governator to automatically switch
from 400000 to 100000.

I know but I need to port android stuff on it and change the glamo to
re-enable
pan.

This is a test. There are some open issue  like flowcontrolled during
frequency scaling.
I have some idea but I think that is a general linux-problem

The 2.6.31 kernel Lars is building is already booting and can be used
with graphics.

This means you didn't test the resulting kernel in andy-tracking,
right? I think the patches should be tested there.
If the patches apply, is somebody willing to test a binary kernel?

Sounds very useful.

Today I try to rebase all the om-2.6.31 to the linus-git. There are some
problem related
to the adc. What is the correct version?

A working version is in the om-gta02-2.6.31 kernel (since last week).
The patch by Vasily is included there and also a small patch needed to
make the ts work. You might want to check the patches applied to the
s3c-touchscreen-2.6.31 branch.

PS: The patch is under review
