[PATCH v2 0/3] Add TI K3 HSM M4F nodes in device-tree

[Beleswar Padhi <b-padhi@ti.com>]

Some of the TI K3 family of SoCs (like J721S2, J784S4, J722S) have a
HSM (High Security Module) M4F core in the Wakeup Voltage Domain which
could be used to run secure services like Authentication. Add the device
tree bindings and device-tree node definitions for this HSM M4F core.

The HSM M4 core is typically booted early from the bootloader and the
driver for the same is posted in U-Boot mailing list[0].

v2: Changelog:
[Krzysztof Kozlowski]:
 In [PATCH v2 1/3]
 1. Update commit msg to remove redundant "bindings".
 2. Update filename to match compatible.
 3. Remove "address-cells" & "size-cells" property. These belong to the
    device's parent node.
 4. Drop description from firmware-name property.
 5. Fix indentation for DT example.
