I'm slightly confused. 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.
