The ti_clk_register() and ti_clk_register_omap_hw() functions are always called with the parameter of type "struct device" set to NULL, since the functions from which they are called always have a parameter of type "struct device_node". Replacing "struct device" type parameter with "struct device_node" will allow you to register a TI clock to the common clock framework by taking advantage of the facilities provided by the "struct device_node" type. Further, adding the "of_" prefix to the name of these functions explicitly binds them to the "struct device_node" type. The patch has been tested on a Beaglebone board.
