Subject: [PATCH v7 01/16] regulator: dt-bindings: describe the PMU module of the QCA6390 package

From: Bartosz Golaszewski <[email-masked]>
Date: Wed, 10 Apr 2024 14:46:13 +0200

From: Bartosz Golaszewski <[email-masked]>

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.
