Subject: [PATCH v6 0/2] Add support for ltc4162-f/s and ltc4015

This patch series adds support for:
  * LTC4162-F 35V/3.2A Multi-Cell LiFePO4 Step-Down Battery Charger
  * LTC4162-S 35V/3.2A Lead-Acid Step-Down Battery Charger
  * LTC4015 35V/3.2A Multichemistry Buck Battery Charger Controller

The LTC4162-L/F/S variants and LTC4015 share a common set of registers. The
difference lies in the resolution value of the scaling factor for battery
voltage and battery current measurement, input voltage, and input current for
different battery chemistries. The difference also includes the calculation of
setting and getting the actual voltage setting applied to the charge voltage,
as well as getting the die temperature.

changes in v6:
ltc4162:
  - Changed ibat_resolution_uv and vin_resolution_mv to ibat_resolution_pv and
    vin_resolution_uv respectively to reflect correct units.

changes in v5:
bindings:
 - Add Acked-by tag from Krzysztof Kozlowski.

ltc4162:
  - No changes.

changes in v4:
 - Arranged compatible strings in alphabetical order.

changes in v3:
 - Described differences in the programming model between variants/devices in
   the commit message.

changes in v2:
 - Modified commit message describing differences between variants/devices.
