Subject: [PATCH] ARM: dts: sun7i: Use axp209.dtsi on A20-OLinuXino-Micro
Date: Sat, 25 Mar 2017 18:05:33 -0300 [thread overview]
Message-ID: <20170325210533.4766-1-ezequiel@vanguardiasur.com.ar> (raw)
This commit makes use of the axp209.dtsi file to define the
AXP209 PMIC. While here, define the rails that are enabled on
this board.
Tested checking the regulator voltage varies according to the
CPU frequency.
