Nishanth Menon	194dd74ad9	DRA7: add ABB setup for MPU voltage domain ... Patch adds modification to shared omap5 abb_setup() function, and proper registers definitions needed for ABB setup sequence. ABB is initialized for MPU voltage domain at OPP_NOM. Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Tom Rini <trini@ti.com>	2014-01-24 11:41:17 -05:00

Andrii Tseglytskyi	4d0df9c1e9	OMAP3+: introduce generic ABB support ... Adaptive Body Biasing (ABB) modulates transistor bias voltages dynamically in order to optimize switching speed versus leakage. Adaptive Body-Bias ldos are present for some voltage domains starting with OMAP3630. There are 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.
