Just to follow up, I modified config/example/fs.py to contain the following
test_sys.cpu_clk_domain = SrcClockDomain()
test_sys.cpu_clk_domain.clock = ['1GHz','700MHz','400MHz','230MHz']
test_sys.cpu_clk_domain.domain_id = 0
test_sys.cpu_clk_domain.voltage_domain = VoltageDomain(voltage =
['1V','0.95V','0.90V','0.85V'])
test_sys.dvfs_handler.domains = [test_sys.cpu_clk_domain]
test_sys.dvfs_handler.enable = True
