Hello,

This is a series adding support for the EIP-150, which is a crypto block
containing:
- a public key accelerator
- a random number generator
- an interrupt controller

The series is a bit long but every subsystem may take its own share
independently. I might want to split it into several chunks in the
future if it expands but at as for now, here is the full picture.

For instance, the clock part has grown due to the inputs From Stephan
Boyd (addition of Kunit tests + a couple of misc preliminary changes).
Link: https://lore.kernel.org/linux-clk/20260129201003.288605-1...

Regarding the big engine, the EIP-28 Public Key Accelerator, it
currently only supports RSA, but more algorithms might be added
later. The hardware supports (EC)DSA and (EC)DH. It also requires a
firmware.

The very last patch adds the block in the Renesas RZ/N1D DTSI, as this
is the platform I am using this hardware one.

Thanks,
Miquèl
