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.
