Subject: [PATCH v8 10/10] ARM: dts: sun8i: q8-common: Add AXP223 PMIC device
 and regulator nodes
In-Reply-To: <1455242567-17880-1-git-send-email-wens@csie.org>
References: <1455242567-17880-1-git-send-email-wens@csie.org>
Message-ID: <1455242567-17880-11-git-send-email-wens@csie.org>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

A23/A33 Q8 tablets have an X-Powers AXP223 PMIC connected via RSB. Its
regulators provide power to various parts of the SoC and the board.

Also add lcd regulator supply for simplefb and update the existing
vmmc-supply for mmc0.
