Message-Id: <6c9e5c21df09a1feb1b00aa000c3c0f77e51eac3.1474621107.git.moinejf@free.fr>
Date: Fri, 23 Sep 2016 09:00:42 +0200
From: Jean-Francois Moine <moinejf@...e.fr>
To: Chen-Yu Tsai <wens@...e.org>, Mark Rutland <mark.rutland@....com>,
Rob Herring <robh+dt@...nel.org>

Subject: [PATCH v3 3/4] regulator: axp20x: add the AXP803
The X-Powers AXP803 PMIC is close to the AXP809 with more outputs.
It is used in some Allwinner boards as the Sinovoip BananaPi M64
and the Pine A64.
