The entering of L23 lower-power state is optional, because the
connected endpoint might doesn't support it. So pcie-brcmstb shouldn't
print an error if it fails.

Which part of the PCIe spec states that the L23 Ready state is optional?

tbh i don't have access to the PCIe spec, so my statement based on
this comment [1].

Please tell, how can we proceed here? In case L23 is required by the
specs the driver also need adjustment.

Best regards

Thanks
