 In this patch set the following is provided:
  - MFD Core support and DT bindings documentation.
- - Fix to IIO framework (inkern.c, of_iio_channel_get_by_name()) to correctly
-   return NULL for failure cases.
  - IIO GPADC support and DT bindings documentation.
  - Power Supply Charger support and DT bindings documentation.
- - Add Dialog vendor prefix for DT.
+ - Update to MAINTAINERS file to add DA9150 files to Dialog support list.
+ - Update to IIO ABI document to add info regarding input current readings.
 
- To keep patch submission from being too large, support for GPIO and Fuel-Gauge
- will come after initial support patches are accepted.

+Changes in v3:
+- IRQ register and remove helper functions removed from MFD, deemed unnecessary.
+  Drivers using helper functions updated to use direct calls to relevant
+  kernel framework functions.
+- MFD I2C file removed and code folded into -core file as requested.
+- MFD core now buildable as driver module.
+- Platform data structure definition moved into core header, pdata.h removed.
+- Update functions in GPADC driver to be static, where appropriate.
+- Change units of GPADC readings to match ABI documentation. Updates to charger
+  driver also made to align with this modification.
+- Refactor GPADC temp calculations to use scale & offset method.
+- Scale values now returned as FRACTIONAL to allow for accurate conversion in
+  user-space.
+- Tidy up of GPADC scale, offset and raw functions to return from case statements
+  with correct return types.
+- Update GPADC channel macros naming to prefix with DA9150, prevent conflict.
+- GPADC GPIO voltage readings actually in 6V range, updated accordingly.
+- Addition to IIO ABI document to add details on input current readings.
+- Small style updates to address comments.
+
+Changes in v2:
+ - Drop devicetree prefix patch as this is being dealt with separately.
+ - IIO framework fix patch removed from set, has already been accepted/merged.
+ - Use __ instead of _ for protecting #ifdefs in headers.
+ - Moved private data & definitions to source files and remove unwanted headers.
+ - Bug fix to EXPORT_SYMBOL for common functions in MFD core used by
+   sub-devices, so they can be correctly built as kernel modules.
+ - Removed unnecessary channels from GPADC IIO driver to simplify code.
+ - For GPADC IIO driver, VBAT reading now provides scale and offset values as it
+   is a linear scale.
+ - GPADC read code refactored to make it tidier.
+ - Remove use of flag to indicate GPADC availability. IIO framework should
+   indicate need to defer if it's not yet instantiated.
+ - Unwanted comments removed.
+ - Removed conditional shutdown of device (Charger/MFD) as this is not needed.
+ - Removed AC type supply from charger as device cannot differentiate. Now just
+   uses USB supply type.
+ - Removed use of invalid-tbat flag from platform data as it doesn't really add
+   anything to the driver except forcing battery present status.
+ - Bug fix for checking of usb_phy validity in Charger probe() function.
+ - Addition of common IRQ release function to allow sub-devices to explicitly
+   tidy up IRQs when devm clean up is too late.
+ - Improved tidy up of resources in charger.
+ - Fix location of IIO GPADC related devicetree binding document so it now
+   resides correctly under 'adc' directory.
+ - Add update to MAINTAINERS file to include these files in Dialog support list.
