From f70444980b23f5f52025aa6b7d22233312dea136 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 13 Dec 2014 12:40:45 +0100 Subject: [PATCH] sunxi: axp221: Add Kconfig help and sane defaults for typical ldo usage Some of the ldo-s of the axp221 are used in the same way on most boards, add comments to the Kconfig help text to reflect this, and give them defaults matching their typical usage.
