GPIO support for MX53

The BSP which i installed for the ConnectCore MX53 development board does not support the full capabilities of the GPIO, it uses the mx51 GPIO class instead of the mx53. The documentation refers to the ConnectCore_MXF.GPIO class which is the required class that supports all capabilities, but it is not part of the BSP i have installed. Have i missed an update of the BSP for the MX53 or is there an other option to include the proper classes/components?

which capabilities are missing?
