Subject[PATCH v5 0/6] Add support for DA9150 Fuel-Gauge
Message-ID<q7trj-6Qv-3@gated-at.bofh.it>
This patch set adds support for the Dialog DA9150 Fuel-Gauge.

In this patch set the following is provided:
 - MFD Core and DT bindings updates.
 - Power Supply Fuel-Gauge support and DT bindings documentation.

This patch set is baselined against the v4.2 kernel version.

Changes in v5:
 - Rebase to v4.2

Changes in v4:
 - MFD, Power, DT: Update DT compatible & driver name strings for Fuel Gauge,
                   in line with maintainers request.
 - Power: Update Kconfig and Makefile to use BATTERY_* for config entry instead
          of FG_*. Also fuel-gauge module now depends on MFD not Charger.
 - Power: Added helper function to simplify single attribute accesses using QIF
          interface of fuel-gauge.
 - Power: Use of devm_* functions for IRQ and power_supply registration.
 - Power: Added checking of result from platform_get_irq_byname().

Changes in v3:
 - MFD: Some tidy up of code (gotos, dropped FG header, DEFINE_RES_IRQ_NAMED)
 - MFD & Power: Drop use of callback function for temperature reading, as
                requested by Lee Jones.
 - MFD (DT): Binding doc update to flesh out example text.
 - MFD (DT): New patch to change MFD binding doc to use relative paths.
 - MFD: New patch to use DEFINE_RES_IRQ_NAMED for all other IRQ resources.

Changes in v2:
 - Moved temp callback function prototype to be part of power fuel-gauge patch,
   as requested by Lee Jones.

In reply to#1222675
When referencing other DT bindings documentation, use relative
path rather than absolute.

Changes in v5:
 - Rebase to v4.2

Changes in v4:
 - Update compatible string of fuel-gauge to "dlg, da9150-fuel-gauge". Also
   made similar change to driver name to keep things consistent.

Changes in v3:
 - Use DEFINE_RES_IRQ_NAMED() helper for defining FG IRQ resource.
 - Unwanted new line & comments removed.
 - Remove gotos which can be replaced with straight forward return calls.
 - Add enum for indexing MFD cells list, which is used to assign pdata for FG
   sub-device.
 - Remove use of function pointers for QIF related read/write functions as
   currently only I2C supported, so call I2C functions directly.
 - Fold fg.h contents into core.h.

Changes in v2:
 - Moved temp callback function prototype to be part of power fuel-gauge patch,
   as requested by Lee Jones.

Changes in v4:
 - Update compatible string of fuel-gauge to "da9150-fuel-gauge".
 - Node name tidy up, relating to maintainer comments on fuel-gauge DT
   binding doc.
 - Removed Ack to patch from Lee Jones, as this has now been modified slightly
   and didn't want to make assumptions of approval.

Changes in v3:
 - Removal of unwanted new-line.
 - Flesh out example bindings usage.

Changes in v2:
 - N/A
