Pratheesh Gangadhar f1a304e794 UIO: add PRUSS UIO driver support
This patch implements PRUSS (Programmable Real-time Unit Sub System)
UIO driver which exports SOC resources associated with PRUSS like
I/O, memories and IRQs to user space. PRUSS is dual 32-bit RISC
processors which is efficient in performing embedded tasks that
require manipulation of packed memory mapped data structures and
handling system events that have tight real time constraints. This
driver is currently supported on Texas Instruments DA850, AM18xx and
OMAP-L138 devices.
For example, PRUSS runs firmware for real-time critical industrial
communication data link layer and communicates with application stack
running in user space via shared memory and IRQs.

menuconfig UIO
tristate "Userspace I/O drivers"
depends on !S390
help
Enable this to allow the userspace driver core code to be
built. This code allows userspace programs easy access to
kernel interrupts and memory locations, allowing some drivers
to be written in userspace. Note that a small kernel driver
is also required for interrupt handling to work properly.
If you don't know what to do here, say N.

Driver for Hilscher CIF DeviceNet and Profibus cards. This
driver requires a userspace component called cif that handles
all of the heavy lifting and can be found at:
<http://www.osadl.org/projects/downloads/UIO/user/>
To compile this driver as a module, choose M here: the module
will be called uio_cif.

tristate "Userspace I/O platform driver with generic IRQ handling"
help
Platform driver for Userspace I/O devices, including generic
interrupt handling code. Shared interrupts are not supported.
This kernel driver requires that the matching userspace driver
handles interrupts in a special way. Userspace is responsible
for acknowledging the hardware device if needed, and re-enabling
interrupts in the interrupt controller using the write() syscall.
If you don't know what to do here, say N.
config UIO_AEC
tristate "AEC video timestamp device"
depends on PCI
help
UIO driver for the Adrienne Electronics Corporation PCI time
code device.
This device differs from other UIO devices since it uses I/O
ports instead of memory mapped I/O. In order to make it
possible for UIO to work with this device a utility, uioport,
can be used to read and write the ports:
git clone git://ifup.org/philips/uioport.git
If you compile this as a module, it will be called uio_aec.
