This patch set now deals with the issues reported. Patch 1 amends the binding documentation mention clock-names property for the "xtal" and "clkin" parent clock inputs of Si5351 variants. Patch 2 adds the clock-names property for the SolidRun CuBox using Si5351 with a fixed oscillator connected to "xtal" input. Patch 3 reworks the way we claim parent clocks by using devm_clk_get() for both DT and platform_data based registration. Also, properly check for errors returned by devm_clk_get() and prepare/enable the parent clocks. Patch 4 introduces a function to reset PLLs on rate change. This should improve generated clock output stability. I currently have no scope at hand to actually test that properly, so there may be more issues remaining. @Michael, Jean-Francois: Please test and report if there are still issues remaining.
