Merge patch series "Print version of the DM firmware"
Moteen Shah <m-shah@ti.com> says:
This patch series adds the functionality to print the DM firmware
version being used. Before requesting TISCI for the DM version we
first check if the DM split mode capability exists, if yes, we proceed
onto making the call to TISCI for retrieving the version information.
DM split mode capability indicates that the DM is a separate binary
altogether and has its own versioning information similar to TIFS.
