You are correct that the FW comes with DT, and in typical case, you
wouldn't need this.

However, there are still new/updated drivers being developed, and
sometimes requires new/changes in DT binding. So, the DT that comes with
the FW can get out of date, and will lack the support for new drivers.
Certain version of the FW allows overriding the DT that comes with the
FW. So, we are providing the in-kernel DT to allow developers to provide
the updated device tree for newer kernels. This patch series is bringing
the in-kernel DT closer to what the latest FW is providing to avoid
potential conflicts.

Suravee
