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? -- Pali Rohár pali.rohar@gmail.com

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

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. -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
