On January 14, 2026 thus sayeth Beleswar Padhi:

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
device-tree node definitions for this HSM M4F core. The bindings for
this has already been merged[0].

The HSM M4 core is typically booted early from the bootloader and the
driver for the same is posted in U-Boot mailing list[1].

Nice! Amazing job cleaning up the remote core drivers Beleswar! And 
defining them so well in DT for us.  For the series
