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.

Patch adds a call of abb_setup() function, and proper registers
definitions needed for ABB setup sequence. ABB is initialized
for MPU voltage domain.

contains minor comments fixes.
v03: series contains:
- clearing pending ABB interrupts before beginning of ABB configuration.
- clearing ABB "setup" and "control" registers before beginning of
ABB configuration.
- removing superfluous wait on ABB "in transition" do
Hi,
Thank you for review.

Hi,
Tom, Nishant, could you please review this series ?
Thank you in advance.
Regards,
