If you say yes here you get support for the TPS6586X series of
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".
