Subject: [PATCH v4 2/6] mfd: da9150: Update DT bindings for Fuel-Gauge support

Signed-off-by: Adam Thomson <Adam.Thomson.Opensource@...semi.com>
---

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
