Subject: [PATCH v2 03/14] staging: typec: fusb302: Set max supply voltage to 5V
Date: Tue, 15 Aug 2017 22:04:51 +0200	[thread overview]
Message-ID: <20170815200502.17339-4-hdegoede@redhat.com> (raw)
In-Reply-To: <20170815200502.17339-1-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.
