XPowers AXP288 is a customized PMIC found on some Intel Baytrail-CR platforms. It comes with sub-functions such as USB charging, fuel gauge, ADC, and many LDO and BUCK channels.
By extending the existing AXP20x driver, this patchset adds basic support for AXP288 PMIC with GPADC as one MFD cell device driver. It also adds hooks for ACPI opregion handler driver which can be used to handle ACPI requests. Currently, the PMIC driver in this patchset does not support platform data enumeration. But when ACPI _DSD and unified device properties become available, cell devices with platform data will be added. This patch does not use intel_soc_pmic core for i2c and regmap handling in that axp288 shares similar programming interface with other Xpower PMICs supported in axp20x.c. Therefore, extending axp20x.c to include axp288 makes more sense.
