5f53e534ac arm64: versal: Enable power domain driver and its dependencies
Enable power domain driver to configure pmufw config object and request
node for all the IP's that are enabled in DT.

This driver depends on mailbox and IPI driver, hence enable them as well.
Add ARCH_VERSAL in the depends on of mailbox Kconfig to compile for
Versal platforms.

456305ec59 mailbox: apple: Add driver for Apple IOP mailbox
This mailbox driver provides a communication channel with the
Apple IOP controllers found on Apple SoCs.  These IOP controllers
are used to implement various functions such as the System
Manegement Controller (SMC) and NVMe storage.  It allows sending
and receiving a 96-bit message over a single channel.

The header file with the struct used for mailbox messages is taken
straight from Linux.

0f67e2395b mailbox: add Tegra186 HSP driver
Tegra186's HSP module implements doorbells, mailboxes, semaphores, and
shared interrupts. This patch provides a driver for HSP, and hooks it
into the mailbox API. Currently, only doorbells are supported.

8961b52424 mailbox: implement a sandbox test
This adds a sandbox mailbox implementation (provider), a test client
device, instantiates them both from Sandbox's DT, and adds a DM test
that excercises everything.

6238935d01 Add a mailbox driver framework/uclass
A mailbox is a hardware mechanism for transferring small message and/or
notifications between the CPU on which U-Boot runs and some other device
such as an auxilliary CPU running firmware or a hardware module.

This patch defines a standard API that connects mailbox clients to mailbox
providers (drivers). Initially, DT is the only supported method for
connecting the two.

The DT binding specification (mailbox.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.
