i915 driver can't work with CML-R CPU and RKL PCH

I got an hardware which has CML-R CPU and TigerLake PCH, here is the cpu info lscpu.log and the booting kernel log journalctl-k-b.log.

https://cgit.freedesktop.org/drm-tip/tree/drivers/gpu/drm/i915/intel_pch.c#n120 Denoted that the TigerLake PCH can only work with TigerLake and RocketLake CPU.

May I know if it is an allowed combination for Linux i915 driver?
