From: Mike Turquette <mturque...@linaro.org> Adaptive Body-Bias ldos are present for some voltage domains starting with OMAP3630. They have three modes of operation:
* Bypass - the default, it just follows the vdd voltage * Foward Body-Bias - applies voltage bias to increase transistor performance at the cost of power. Used to operate safely at high OPPs * Reverse Body-Bias - applies voltage bias to decrease leakage and save power. Used to save power at lower OPPs This series adds the ABB code and per-voltage domain data for OMAP3630 and OMAP4430. Newer OMAP4 chips and OMAP5 will need this data populated once those platforms have OPP and voltage tables. The voltage domain scaling sequence is modified use these new functions. This series build on top my previous series, "Introduce .get_voltage callback into voltdm"[1]. While not strictly necessary that series does take some steps to eliminate one combination of ABB and VP/VC modes that is out-of-spec.
