+          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".
