[PATCH v5 03/18] dt-bindings: regulator: describe the PMU module of the QCA6390 package

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski at linaro.org>

The QCA6390 package contains discreet modules for WLAN and Bluetooth. They
are powered by the Power Management Unit (PMU) that takes inputs from the
host and provides LDO outputs. This document describes this module.
