[PATCH 0/4] Maxim Semiconductor MAX1721x power_supply driver

["Alex A. Mihaylov" <minimumlaw@rambler.ru>]

Maxim Semiconductor MAX1721x series chip is standalone fuel gauge
for singlecell (MAX17211) or multicell (MAX17215) batteries.
This device use OneWire (W1) interface with W1-Family code 0x26

PATCHES:
  1. Introduce regmap infrastructure over Maxim/Dalas OneWire (W1) bus
  2. Introduce new OneWire (W1) family 0x26 with slave device Maxim
    Semconductor MAX17211/MAX17215 Fuel Gauge IC
  3.Introduce Maxim Semiconductor MAX17211/MAX17215 Standalone Fuel Gauge
    IC support for power_supply class driver
  4. Fix W1 slave exchange with second device on probe step
