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

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 will be posted shortly.
