The USB controller requires specific clocks to be enabled. On Exynos 850 / 3830, the DWC3 glue driver needs a “ref” clock and, on some variants, a “susp_clk” (suspend clock). If these clocks are not correctly specified in the device tree, the controller will fail to initialise. Debug messages about missing or unsuspended clocks are a strong indicator of this problem. A patch from early 2017 explicitly removed a debug message that printed when the suspend clock was not specified, because that clock is optional and many boards work fine without it. Nevertheless, you should verify your clock tree configuration.
