This framework adds API functions for enabling/ disabling FPGA bridges under kernel control. This allows the Linux kernel to disable FPGA bridges during FPGA reprogramming and to enable FPGA bridges when FPGA reprogramming is done. This framework is be manufacturer-agnostic, allowing it to be used in interfaces that use the FPGA Manager Framework to reprogram FPGA's. The functions are: * of_fpga_bridge_get * fpga_bridge_put Get/put an exclusive reference to a FPGA bridge. * fpga_bridge_enable * fpga_bridge_disable Enable/Disable traffic through a bridge. * fpga_bridge_register * fpga_bridge_unregister Register/unregister a device-specific low level FPGA Bridge driver. Get an exclusive reference to a bridge and add it to a list: * fpga_bridge_get_to_list To enable/disable/put a set of bridges that are on a list: * fpga_bridges_enable * fpga_bridges_disable * fpga_bridges_put Signed-off-by: Alan Tull <atull@opensource.altera.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
