Power Management chips.
This driver provides common support for accessing the device,
additional drivers must be enabled in order to use the
functionality of the device.
This driver can also be built as a module. If so, the module
will be called tps6586x.

If you say yes to this option, support will be included for the
built-in PM8921 PMIC chip.
This is required if your board has a PM8921 and uses its features,
such as: MPPs, GPIOs, regulators, interrupts, and PWM.
Say M here if you want to include support for PM8921 chip as a module.
This will build a module called "pm8921-core".

This is the IRQ driver for Qualcomm PM 8xxx PMIC chips.
This is required to use certain other PM 8xxx features, such as GPIO
and MPP.

If you say yes here you get support for RTC function in Marvell
88PM860x chips.
This driver can also be built as a module. If so, the module
will be called rtc-88pm860x.
