TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.

Some TI Keystone 2 and K3 family of SoCs contain a system controller
(like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and
the Device Management and Security Controller on AM65x SoCs) that manage
the low-level device control (like clocks, resets etc) for the various
hardware modules present on the SoC. These device control operations are
provided to the host processor OS through a communication protocol
called the TI System Control Interface (TI SCI) protocol.
This patch adds a power domain driver that communicates to the system
controller over the TI SCI protocol for performing power management of
various devices present on the SoC. Various power domain functionalities
are achieved by the means of different TI SCI device operations provided
by the TI SCI framework.
This code is loosely based on the drivers/soc/ti/ti_sci_pm_domains.c
driver of the Linux kernel.

This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:
- fet enable/disable/querying
- getting and setting of charge state
Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.
The device tree binding is from Linux, but only a small subset of
functionality is supported.
