Hi Krzysztof,

First bad commit (maybe != root cause):

commit: 552418658acd6302e971c7137cb7d3108e464829 [10/16] clk: socfpga: use ARCH_INTEL_SOCFPGA also for 32-bit ARM SoCs (and compile test)
config: arm64-randconfig-r016-20210408 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project 56ea2e2fdd691136d5e6631fa0e447173694b82c)
