During the merging of v6 several patches were left out. This v7 comprises
all the patches that are still pending.

AXP209 and AXP202 are the PMUs (Power Management Unit) used by A10, A13
and A20 SoCs and developed by X-Powers, a sister company of Allwinner.
AXP20x comprises an adaptive USB-Compatible PWM charger, 2 BUCK DC-DC
converters, 5 LDOs, multiple 12-bit ADCs of voltage, current and temperature
as well as 4 configurable GPIOs.
This set of patches introduces the core driver and support for two different
subsystems:
- Regulators
- PEK (Power Enable Key)
Changes since v1:
- Added a new standalone patch for defconfig
- MFD core:
* Removed axp,system-power-controller property
- Bindings documentation:
* Corrected description for dcdc-workmode property
* Removed unused axp20x-pek compatible
- Input misc PEK driver:
* Fixed seconds in lower case
- Regulators subsystem:
* Fixed axp20x_set_suspend_voltage()
* Switched to using multi-bit control for regulators
* When "regulators" node is not found driver doesn't quit
* Driver is now using devm_regulator_register()
* Added module_platform_driver() instead of subsys_initcall()
- DT:
* Added new DTSI for AXP209
* Added support for cubietruck and olinuxino-micro
Changes since v2:
- Added a new patch for multi_v7_defconfig to enable MFD core
and subsystems
- DT:
* Dropped axp,system-power-controller property from DTS
* Moved compatible and interrupt-related properties from the
DTSI file to the DTS board files
- Regulators subsystem:
* Deleted useless struct axp20x_regulators
* Added a warning when out of specs values are used for the
dcdc frequency
- MFD core:
* Fixed coding style
* Removed IDs from device table for i2c
- Bindings documentation:
* Several corrections and fixes
Changes since v3:
- Removed x-powers-axp209.dtsi file
- Rewritten bindings document
- MFD core:
* Fixed casting
* Better comments / documentation
- Input misc PEK driver:
* Timings are now expressed in ms and the sysfs appies the
closest possible value
* No more useless pretty-printing
* Removed devm_request_threaded_irq in favour of
devm_request_any_context_irq
* Moved from input attributes to platform device attributes
- Regulators subsystem:
* Removed suspend mode (axp20x_set_suspend_voltage)
* Added regulators input supply
- DT:
* DTs doesn't include anymore the dtsi
* Added input supplies for regulators
Changes since v4:
- Removed regulator patches already applied / acked by Mark Brown
- Input misc PEK driver:
* Don't print anymore the "us" unit
* Added cleanup for attributes when unbindind the device
* Fixed error code returned when device_create_file() fails
- DT:
* Enable all the regulators on at boot-time
* Removed min and max microvolts for all the regulators but DCDC2
* Moved the axp_ipsout regulator outside the MFD node
- MFD core:
* The supply regulators are now specified in the MFD driver using
regulator_bulk_register_supply_alias() and the .parent_supplies
in the MFD cell
Changes since v5:
- Added ACKs
- Fixed compilation warning (reported by Hans De Goede)
- Vendor-prefixes are now sorted
- Removed DT patch
