53b6aac7b1 dt/bindings: add bindings for optee
Sync with c8bfafb15944 ("dt/bindings: add bindings for optee")
from Linux kernel.

Introduces linaro prefix and adds bindings for ARM TrustZone based OP-TEE
implementation.

32cd25128b firmware: Add basic support for TI System Control Interface (TI SCI) protocol
Texas Instrument's System Control Interface (TI SCI) message protocol is
used in Texas Instrument's System on Chip (SoC) such as those in the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.

The TI SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.

This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.

390ae57c76 dt-bindings: allow child nodes inside the Tegra BPMP
The BPMP implements some services which must be represented by separate
nodes. For example, it can provide access to certain I2C controllers, and
the I2C bindings represent each I2C controller as a device tree node.
Update the binding to describe how the BPMP supports this.

7b9cb49405 ARM: tegra: add BPMP DT bindings
The Tegra BPMP (Boot and Power Management Processor) is a separate
auxiliary CPU embedded into Tegra to perform power management work, and
controls related features such as clocks, resets, power domains, PMIC I2C
bus, etc. These bindings dictate how to represent the BPMP in device tree.
