Subject: [PATCH 13/18] power: supply: bq24190_charger: Export 5V boost converter as regulator
Date: Sun, 6 Aug 2017 14:35:50 +0200 [thread overview]
Message-ID: <20170806123555.5124-14-hdegoede@redhat.com> (raw)
In-Reply-To: <20170806123555.5124-1-hdegoede@redhat.com>
Register the 5V boost converter as a regulator named
"regulator-bq24190-usb-vbus". Note the name includes "bq24190" because
the bq24190 family is also used on ACPI devices where there are no
device-tree phandles, so regulator_get will fallback to the name and thus
it must be unique on the system.
