Hi Stephen,

Test that clks registered with 'struct clk_parent_data' work as intended and can find their parents.
When testing this on arm64, I see the error below. The error is only seen if I boot through efi, i.e., with "-bios QEMU_EFI-aarch64.fd" qemu parameter.
Any idea what might cause the problem ?
I noticed that the new overlay tests fail as well, also with "path '/' not found".
[Maybe] answering my own question: I think the problem may be that there is no devicetree file and thus no devicetree root when booting through efi (in other words, of_root is NULL). Would it make sense to skip the tests in that case ?
Thanks, Guenter
Thanks, Guenter
