[PATCH v3 0/2] Add TI K3 HSM M4F nodes in device-tree

[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].

v3: Changelog:
[Nishanth]:
 1. Use generic node name 'remoteproc'
 2. Use label 'hsm' instead of 'hsm_m4fss'
 3. Add a comment for separate SRAMs
 4. Change firmware-name value to match existing naming convention
 5. Change status to 'reserved' and add a commment
 6. Re-order bootph-pre-ram property before vendor properties
 7. Update commit message to call out rationale for putting firmare-name
    in SoC level dtsi
 8. Dropped [PATCH v2 1/3] in v3 as it is already merged[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.
