From bd425113a186f6dc104e07cd501916dc51f25e6a Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 29 Mar 2016 17:22:25 +0800 Subject: [PATCH] mfd: axp20x: Add bindings for AXP809 PMIC This patch adds the basic and regulator bindings for the X-Powers AXP809 PMIC. Also update the DC-DC converter operating frequency for AXP22X/AXP80X.
