* If compiled with EXT_RESOURCES look up the "biu" and "ciu" clocks in the DT * Don't use custom property "bus-frequency" but the standard one "clock-frequency" * Use the DT property max-frequency and fall back to 200Mhz if it don't exists * Add more mmc caps suported by the controller * Always ack all interrupts * Subclassed driver can supply an update_ios so they can handle update the clocks accordingly * Take care of the DDR bit in update_ios (no functional change since we do not support voltage change for now) * Make use of the FDT bus-width property
