You got me wrong.  I was asking you to drop property 'clock-names' only,
not 'clocks' together.  I do not think it works if you drop property
'clocks', because I see that dw_i2c_plat_probe() will fail if
devm_clk_get() fails.  Did you test the patch before posting it out?

I am sorry that my Hikey board don't work well. I will fix my board and test
it.

Thank you very much.
