about the comments from V1::
- Krzysztof: Filename - same as bindings, so nuvoton,npcm845-clk.h
In NPCM7XX we use the same include file and clock source
dt-binding
https://elixir.bootlin.com/linux/v5.19-rc1/source/Documentation/devicetree/bindings/clock/nuvoton,npcm750-clk.txt
dt-binding include
https://elixir.bootlin.com/linux/v5.19-rc1/source/include/dt-bindings/clock/nuvoton,npcm7xx-clock.h
we prefer to be align with our older BMC version

- Krzysztof: Dual license, same as bindings.
modified in the file * SPDX-License-Identifier: (GPL-2.0-only OR
BSD-2-Clause) */
the same license approved in en7523-clk include file and pushed to
Linux kernel 5.19 :
