Merge remote-tracking branch 'spi/topic/xilinx' into spi-next (2015-02-08 11:17:01 +0800)
----------------------------------------------------------------
spi: Updates for v3.20
The major highlight this release is a refactoring of the core to allow
us to run synchronous transfers in the context of the caller when there
is no contention for the bus. This improves performance in the very
common case by eliminating context switches and reducing the number of
hardware setup and teardown operations we need to perform.
Other changes:
- New drivers for DLN-2 USB-SPI adapter and ST SPI controllers.
- A big round of cleanups, performance and feature improvements
for the xilinx driver from Ricardo Ribalda Delgado.
- A wide range of smaller cleanups, fixes and feature improvements
throughout the subsystem.
