[RFC 0/6] Add support for Ettus Research E31x devices PMU

[Virendra Kakade]

E31x devices are embedded devices made by Ettus Research which have
a Zynq based FPGA architecture. This code adds driver support for the
charger and battery to enable query of properties like voltage,
temperature, charge and online status among others via the device tree
on addition of overlay.

The driver follows a MFD structure with a parent driver and two
sub-drivers.

* Patch 1 and 2: Add device bindings and E31x-PMU MFD device driver

* Patch 3 and 4: Add device bindings for the charger and the sub-driver
  for it. This driver shares the register map from its parent MFD
  driver.

* Patch 5 and 6: Add device bindings for the battery and the sub-driver
  for it. Register map is re-used.
