Pull spi updates from Mark Brown:
"Since Grant is even more specacularly busy than usual for the time
being I've been collecting SPI patches for him for this release -
probably things will revert back to Grant before the next release.There's nothing too exciting here, mostly it's simple driver specific
stuff:- Add spi: to the modaliases of SPI devices to provide namespacing.
- A driver for AD-FMCOMMS1-EBZ.
- DT binding for Orion.
- Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.There may be a few more fixes I've missed, people keep sending me new

No call was being made by the GPIO driver to put the GPIO into output
mode meaning that the calls to gpio_set_value() which were being done
were not valid. A similar issue appears to exist with the DT GPIO
requests but as they appear to be being used for pinmux it's less clear
to me that we want to configure them.Without this fix Cragganmore systems can't talk to their SPI devices.

When gpio_request() fails the driver logged the failure but while it'd
try to print an error code in the non-DT case it didn't pass the error
code in so garbage would be logged and in the DT case the error wasn't
logged.Further, in the non-DT case the error code was then overwritten with -EBUSY
depriving the caller of information and breaking automatic probe deferral
pushing back from the GPIO level. Also reformat the non-DT log message
so it's not word wrapped and we can grep for it.Signed-off-by: Mark Brown

…it/swarren/linux-tegra into next/clk

This branch contains numerous changes required as a baseline in order to
convert Tegra to the common clock framework. The intention was to also
include patches to actually convert Tegra to the common clock framework.
However, those patches appeared late in the kernel cycle and currently
cause regressions on some boards, so were dropped for now.* 'for-3.6/common-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:

Trivial simplification. Instead of requiring spi master drivers to
always set the bus number (even when a dynamic number is desired),
this patch modifies spi_alloc_master() to initialize num_chipselect to
1 (because there will always be at least one CS) and bus_num to -1 for
dynamic allocation. This simplifies the code needed to be written for
drivers.Signed-off-by: Grant Likely
