fpga: Add COMPILE_TEST to all drivers

2016-11-29T21:51:44Z

Like Zynq the Altera drivers compile fine on x86 and others too, so make it easier to compile test this stuff. A10 requires REGMAP_MMIO to compile, so be explicit rather than relying on it via ARCH_SOCFPGA. Signed-off-by: Jason Gunthorpe Acked-by: Alan Tull

fpga: add altera freeze bridge support

2016-11-10T16:03:36Z

Add a low level driver for Altera Freeze Bridges to the FPGA Bridge framework. A freeze bridge is a bridge that exists in the FPGA fabric to isolate one region of the FPGA from the busses while that one region is being reprogrammed.

ARM: socfpga: fpga bridge driver support

2016-11-10T16:03:36Z

Supports Altera SOCFPGA bridges: * fpga2sdram * fpga2hps * hps2fpga * lwhps2fpga Allows enabling/disabling the bridges through the FPGA Bridge Framework API functions. The fpga2sdram driver only supports enabling and disabling of the ports that been configured early on. This is due to a hardware limitation where the read, write, and command ports on the fpga2sdram bridge can only be reconfigured while there are no transactions to the sdram, i.e. when running out of OCRAM before the kernel boots. Device tree property 'init-val' configures the driver to enable or disable the bridge during probe. If the property does not exist, the driver will leave the bridge in its current state.

fpga: add fpga bridge framework

2016-11-10T16:03:35Z

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 Signed-off-by: Greg Kroah-Hartman
