Subject: [PATCH v2 2/4] input: gpio-vibra: Allow to use vcc-supply alone to control the vibrator
Date: Wed, 13 May 2020 00:22:03 +0200 [thread overview]
Message-ID: <20200512222205.1456300-3-megous@megous.com> (raw)
In-Reply-To: <20200512222205.1456300-1-megous@megous.com>
Make enable-gpio optional to allow using this driver with
boards that have vibrator connected to a power supply without
intermediate gpio based enable circuitry.
