[PATCH v2 0/2] mfd: act8945a: add Active-semi ACT8945A PMIC MFD driver

[PATCH v2 0/2] mfd: act8945a: add Active-semi ACT8945A PMIC MFD driver

[Wenyou Yang]

This patch set adds support for the Active-semi ACT8945A PMIC
MFD driver. It is a Multi Function Device with the following
subdevices:
 - Regulator
 - Charger

It is interfaced to the host controller using I2C interface,
ACT8945A is a child device of the I2C.

Changes in v2:
 - add more help information in Kconfig.
 - update the file header with short version license and author line.
 - remove unused structure members (dev, i2c_client) of stuct act8945a_dev.
 - use define "PLATFORM_DEVID_NONE" for mfd_add_devices(), instead of '-1'.
 - use more explicit info to indicate the failure to add sub devices.
 - remove the unnecessary print out.
 - substitute MODULE_LICENSE("GPL") for MODULE_LICENSE("GPL v2").
 - use more specific label in Example.
 - add pmic and charger nodes in Example.

Sending out 3 patch-sets for related changes is a pretty
unconventional way of doing things.  In future could you place them
all in the same place, that way all of the patches stay together whist
hopping around our inboxes.
