how is this IP block differnet from the one used in many Lantiq SoCs?
there is already an upstream driver for the RCU IP block on the Lantiq
SoCs: drivers/reset/reset-lantiq.c

some background:
Lantiq was started as a spinoff from Infineon in 2009. Intel then
acquired Lantiq in 2015. source: [0]
Intel is re-using some of the IP blocks from the MIPS Lantiq SoCs
(Intel even has some own MIPS SoCs as part of the Lantiq acquisition,
typically used for PON/GPON/ADSL/VDSL capable network devices).
Thus I think it is likely that the new "Lightening Mountain" SoCs use
an updated version of the Lantiq RCU IP.
