Subject: [PATCH v4 0/8] charger/mfd: max14577: Add support for MAX77836

Hi,

This is a fourth version of patches adding support for
MAX77836 device to the max14577 drivers.

This patchset has been on the lists for quite long time and was already
reviewed by some of the maintainers during previous submissions.
I am in a need of acks from power tree (patches: 3, 5-8).

Generally this should be pulled at once but some parts may be split
and pulled separately in following batches:
 - Patches 1 and 2: as MFD prerequisites,
 - Patches 3-5: adding actual charger code, depends on 1 and 2,
 - Patch 6: fuel-gauge, independent,
 - Patches 7 and 8: only documentation.

Lee Jones said he can take the set through his tree. Still I need acks
from power subsystem.

Everything rebased on current Linus' tree (v3.17-rc2-9-g68e370289c29).

Changes since v3
================
1. Split MFD changes into separate new patches:
   1/8: mfd: max14577: Add defines for MAX77836 charger
   2/8: Map charger device to its own of_node
   Suggested by Lee Jones.

Changes since v2
================
1. charger: Use sysfs instead of DTS for setting the fast charge timer.
   The charger driver now selects the CONFIG_SYSFS and exports
   a DEVICE_ATTR. (suggested by Mark Rutland)
2. Add patch 6 with documentation of exported sysfs entry for fast
   charge timer.
3. charger 3/6: Add missing 'break' in switch parsing valid values
   for fast charge timer.

Changes since v1
================
1. charger 3/5: Add an error message for each unsuccessful parse of DT
   property (suggested by Mark Rutland).
2. charger 3/5: Use 'u32' type for storing values from DT (suggested
   by Mark Rutland).
3. charger 3/5: Remove an error message for memory allocation failure.

The patchset (first and second part of the MAX77836 drivers) has been
on the lists since January. Changelog for the first part of the drivers
(merged):

Krzysztof Kozlowski
