Subject: [PATCH v3 03/11] staging: typec: fusb302: Set max supply voltage to 5V
Date: Wed, 30 Aug 2017 11:48:06 +0200	[thread overview]
Message-ID: <20170830094814.17758-4-hdegoede@redhat.com> (raw)
In-Reply-To: <20170830094814.17758-1-hdegoede@redhat.com>

Anything higher then 5V may damage hardware not capable of it, so
the only sane default here is 5V. If a board is able to handle a
higher voltage that should come from board specific data such as
device-tree and not be hard coded into the fusb302 code.
