staging: comedi: addi_apci_3501: cleanup comments in hwdrv_apci3501.c
The watchdog/timer subdevice in this driver is basically broke. The
subdevice functions abuse the comedi API and the (*insn_config)
simply doesn't work due to it's treating data[0] as a parameter and
not as the config "instruction".
For now, cleanup the comments for the functions so they are at least
readable. Then we can figure out how to fix the subdevice.

staging: comedi: addi_apci_3501: rewrite the analog output support
Currently the analog output subdevice has two support functions:
(*insn_config) - i_APCI3501_ConfigAnalogOutput()
(*insn_write) - i_APCI3501_WriteAnalogOutput()
The (*insn_config) function is used to configure the analog outputs
in either bipolar or unipolar mode. This function abuses the comedi
API since it treats the data[0] value as a parameter instead of as
the config "instruction".
The (*insn_write) function then writes a single value to the desired
analog output channel after doing some sanity checking on the channel
number. The sanity checking is not required since the comedi core has
already done it. Also, the (*insn_write) functions are supposed to
write all the data, indicated by insn->n, to the channel not just a
single value.
Rewrite the support code so it works properly with the comedi API.
The bipolar/unipolar configuration can be determine in the (*insn_write)
by checking the passed insn->chanspec.
Since the unipolar configuration only has 13-bit resolution, we need
to check that the data is in range because the subdevice 'maxdata' is
set to 14-bits for the bipolar mode. If the data is out of range,
output a dev_warn() and return -EINVAL.

goldfish: add QEMU pipe driver
A QEMU pipe is a very fast communication channel between the

something like;
// connect to special device
fd = open("/dev/qemu_pipe", O_RDWR);
// tell which service we want to talk to (must be zero-terminated)
write(fd, "pipeName", strlen("pipeName")+1);

goldfish: add the goldfish virtual bus
This imports the current Google code and cleans it up slightly to use pr_ and
to properly request its resources.
Goldfish is an emulator used for Android development. It has a virtual bus where
the emulator passes platform device information to the guest which then creates
the appropriate devices.
This part of the emulation is not architecture specific so should not be hiding
in architecture trees as it does in the Google Android tree. The constants it
uses do depend on the platform and the platform creates the bus device which then
talks to the emulator to ascertain the actual devices present.

staging: comedi: Allow comedi on ARM
Bernd Porr reports success getting comedi to work on ARM. He writes:
"""
comedi works nicely on the Raspberry PI. I've compiled the rpi kernel
with comedi enabled and it works with the USBDUX-sigma (need to test the
other boards). With comedirecord running I can plot one channel at 1kHz
without buffer overflow (resulting to 70% load).
So, I guess we just need to add "ARM" to Kconfig in the comedi subdir?
depends on BROKEN || FRV || M32R || MN10300 || SUPERH || TILE || X86 || ARM
I'm running just now 3.2.27 but also the development kernel compiles
with ARM enabled (haven't tested yet).

[V2: no code changes, patchset now generated via git format-patch -M]
In staging, rename ramster to zcache
The original zcache in staging was a "demo" version, and this new zcache
is a significant rewrite. While certain disagreements were being resolved,
both "old zcache" and "new zcache" needed to reside in the staging tree
simultaneously. In order to minimize code change and churn, the newer
version of zcache was temporarily merged into the "ramster" staging driver
which, prior to that, had at one time heavily leveraged the older version
of zcache. So, recently, "new zcache" resided in the ramster directory.
Got that? No? Sorry, temporary political compromises are rarely pretty.
The older version of zcache is no longer being maintained and has now
been removed from the staging tree. So now the newer version of zcache
can rightfully reclaim sole possession of the name "zcache".
FYI, this [PATCH 2/5] is simply a "git mv" generated by "git format-patch -M".
