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. Changes v3: - put all file rename changes in 1/5 - add iio documentation for in_current_raw/scale - removed global variables in axp2xx - removed pm callbacks from GPADC - removed ACPI opregion cell device - added scales to ADC current and voltage - removed ADC thermal sensor from sysfs, kernel internal use only v2: - use format -M for 1/4 - minor tweak based on Maxime's review Jacob Pan (5): mfd/axp20x: rename files to support more devices mfd/axp2xx: extend axp20x to support axp288 pmic regulator/axp20x: use axp2xx consolidated header iio/adc/axp288: add support for axp288 gpadc iio: add documentation for current attribute Documentation/ABI/testing/sysfs-bus-iio | 8 + drivers/iio/adc/Kconfig | 8 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/axp288_gpadc.c | 238 +++++++++++++++ drivers/mfd/Kconfig | 7 +- drivers/mfd/Makefile | 2 +- drivers/mfd/axp20x.c | 258 ---------------- drivers/mfd/axp2xx.c | 493 +++++++++++++++++++++++++++++++ drivers/regulator/axp20x-regulator.c | 6 +- include/linux/mfd/{axp20x.h => axp2xx.h} | 66 ++++- 10 files changed, 818 insertions(+), 269 deletions(-) create mode 100644 drivers/iio/adc/axp288_gpadc.c delete mode 100644 drivers/mfd/axp20x.c create mode 100644 drivers/mfd/axp2xx.c rename include/linux/mfd/{axp20x.h => axp2xx.h} (76%) -- 1.9.1
