Subject: [PATCH 12/14] ARM: dts: sun8i: Setup CPU operating points for Onrage PI PC
Date: Thu, 23 Jun 2016 21:21:02 +0200 [thread overview]
Message-ID: <20160623192104.18720-13-megous@megous.com> (raw)
In-Reply-To: <20160623192104.18720-1-megous@megous.com>
From: Ondrej Jirman <megous@megous.com>
Orange PI PC uses SY8106A regulator for fine grained CPUX voltage
regulation. Setup appropriate operating points for the board.
