[PATCH v15 0/6] altera fpga area and fpga bus

From: atull

From: Alan Tull <atull@xxxxxxxxxxxxxxxxxxxxx>

For v15, I'm not using the FPGA Manager as the bus. I'm adding a FPGA Bus;
the FPGA Manager and bridges go below it.

I've gotten enough feedback that my proposals are Altera specific that I am
going with that and changing the bindings to include an 'altr,' prefix.

I've combined the bindings document and the other Documentation/fpga/ document
and done a rewrite there.

Anybody who tried the previous patchset will not have much changes to do to get
this going. The changes are:
* The live tree has a 'altr,fpga-bus' which contains the FPGA Manager and
FPGA Bridges.
* The target path in your overlays needs to be adjusted accordingly.

That said, the changes for each of these submissions is getting to be less and
less; most of these patches are unchanged for v15.

Alan Tull (6):
fpga: add bindings document for fpga area and fpga bus
add sysfs document for fpga bridge class
ARM: socfpga: add bindings document for fpga bridge drivers
fpga: add fpga bridge framework
fpga: fpga-area and fpga-bus: device tree control for FPGA
ARM: socfpga: fpga bridge driver support
