config REGULATOR_CPR3

	bool "CPR3 regulator core support"

	help

	  This driver supports Core Power Reduction (CPR) version 3 controllers

	  which are used by some Qualcomm Technologies, Inc. (QTI) SoCs to

	  manage important voltage regulators.  CPR3 controllers are capable of

	  monitoring several ring oscillator sensing loops simultaneously.  The

	  CPR3 controller informs software when the silicon conditions require

	  the supply voltage to be increased or decreased.  On certain supply

	  rails, the CPR3 controller is able to propagate the voltage increase

	  or decrease requests all the way to the PMIC without software

	  involvement.

	  This driver supports Qualcomm Technologies, Inc. MMSS graphics

	  processor specific features.  The MMSS CPR3 controller only uses one

	  thread to monitor the MMSS LDO voltage requirements. This driver reads

	  initial voltage values out of hardware fuses and CPR target quotient

	  values out of device tree.

	select REGULATOR_CPR3

	help

	  This driver supports Qualcomm Technologies, Inc. KBSS application

	  processor specific features including CPR hardening (CPRh) and two

	  CPRh controllers which monitor the two KBSS clusters each powered by

	  independent voltage supplies. This driver reads both initial voltage

	  and CPR target quotient values out of hardware fuses.
