Hi Can,

quoted

 			} else if (!on && clki->enabled) {
 				clk_disable_unprepare(clki->clk);
+				wait_us = hba->dev_info.clk_gating_wait_us;
+				if (ref_clk && wait_us)
+					usleep_range(wait_us, wait_us + 10);

Hi Stanley,

If wait_us is 1us, it would be inappropriate to use usleep_range() here.
You have checks of the delay in patch #2, but why it is not needed here?

Thanks,
Can Guo.

You are right. I could make that delay checking as common function so it
can be used here as well to cover all possible values.

Thanks for suggestion.
Stanley
