Nokia N900: Adjust MPU OPP values
Hello,
MPU OPP table table (omap36xx_vddcore_volt_data) defined in opp3xxx_data.c does not match Nokia N900 phone. For a long time we have dirty patch in linux-n900 tree for it, see:
https://github.com/pali/linux-n900/commit/4644c5801d7469e2be01d847c61df3d934dadd8c
Now when doing transition to device tree, is there any way how correct MPU OOP table for Nokia N900 could be defined in DT file?

Hmm I'd assume we can just define this in the dts.. Nishanth, got any comments on this one?

We already have definitions in dtb for omap3 OPPs. I think we should start using device tree as default. the oppxx_data.c is sticking around waiting for legacy boot to go away, then those files should be deleted.

Freemangordon, maybe... would it be possible to add (now stable and tested by lot of users) OPP table from Maemo kernel-power to DTS?
