From: Dinh Nguyen <[email protected]> Since the dwc2 hcd driver is currently not looking for a clock node during init, we should not completely fail if there isn't a clock provided. By assigning clk = NULL, this allows the driver, when configured for dual-role mode, to be able to continue loading the host portion of the driver when a clock node is not specified.
