Subject: [PATCH net-next 1/2] dt-bindings: net: airoha: npu: Add
 firmware-name property

Add firmware-name property in order to introduce the capability to
specify the firmware names used for RiscV core/Data section binaries.
This is a preliminary patch to enable NPU offloading for MT7996 (Eagle)
chipset since it requires a different binary with respect to the one
used for MT7992 on EN7581 SoC.

Signed-off-by: Lorenzo Bianconi <lorenzo@...nel.org>
