gpt_clk, pwm1_clk and pwm2_clk parent clock are all ipg_perclk.

No. The gpt has several parents and the one we are using is the ipg
clock. Try a sleep 10 with your patch applied.

You are right. Sounds like gpt_clk can not be defined here. Is it better to pass
three clocks (ipg, ipg_per, ckil) to gpt driver and let gpt decide what to use?
Anyway, it's beyond this patch. I'll keep this line as it was.

Yes, this would be the correct solution.
