[PATCH v7 1/2] mfd/axp20x: extend axp20x to support axp288 pmic
From: Jacob Pan
Date: Tue Oct 07 2014 - 00:18:04 EST
X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar
to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and
AD converters. It also provides extended status and interrupt reporting
capabilities than the devices currently supported in axp20x.c.
In addition to feature extension, this patch also adds ACPI binding for
enumeration.
This consolidated driver should support more X-Powers' PMICs in both device
tree and ACPI enumerated platforms.

+ If you say Y here you get support for the X-Powers AXP202, AXP209 and
+ AXP288 power management IC (PMIC).
This driver include only the core APIs. You have to select individual
components like regulators or the PEK (Power Enable Key) under the
corresponding menus.
