Hi, This is a follow-up to a previous series that was printing a warning when a mux has a set_parent implementation but is missing determine_rate(). The rationale is that set_parent() is very likely to be useful when changing the rate, but it's determine_rate() that takes the parenting decision. If we're missing it, then the current parent is always going to be used, and thus set_parent() will not be used. The only exception being a direct call to clk_set_parent(), but those are fairly rare compared to clk_set_rate(). Stephen then asked to promote the warning to an error, and to fix up all the muxes that are in that situation first. So here it is :) Let me know what you think, Maxime To: Michael Turquette <mturquette@xxxxxxxxxxxx> To: Stephen Boyd <sboyd@xxxxxxxxxx> To: Andreas Färber <afaerber@xxxxxxx> To: Manivannan Sadhasivam
