CLK_OF_DECLARE_DRIVER is for when a platform driver _and_ CLK_OF_DELARE need to "probe" the same device node. But in this patch, the compatible string is being deleted from the driver's match table. Also, are all the registered in hi3660_clk_crgctrl_init() actually needed for the timer? If only a subset, then I would expect to split the code and have the CLK_OF_DECLARE_DRIVER() path register just the clks that matter for the timer, and then leave the rest of the clks to be registered by the probe of the platform driver. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
