This clock is usually called pclock, "apb_pclk" (amba peripheral bus p clock, don't know what P is...) what name does this have on your data sheet? > +The following generic properties as defined in pinctrl-bindings.txt are valid > +to specify in a pin configuration subnode: > +pins - the list of pins that properties in the node > + apply to (either this or "groups" has to be > + specified) > +function - the mux function to select > +bias-disable - disable any pin bias > +bias-pull-up - pull up the pin. Supported only on GPIO0_* pins. > +bias-pull-down - pull down the pin. Supported on all pins except of GPIO0_*. Generic bindings, nice. Put a reference to the file pinctrl-bindings.txt to point this out.
