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

Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.
This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.
However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.
Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate. This is done by
adding a second function that may be used to enable the PHYs.

Marvell engineers tell us:
It seems that many units use the RUNIT clock.
SPI, UART, NAND, TWSI, ...
So it's not possible to clock gate it.
Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

We are currently using an inferior or equal operator for comparing
the transfer frequency with the clock frequency table. Because of
this, we always end up selecting 20Mhz as a frequency, due to the
inequality transfer hz <= 20 Mhz being always true. Fix this by
reversing the inequality, which is how the comparison should be done.

a function __init omap2_mcspi_master_setup().
If omap2_mcspi_master_setup is only used by omap2_mcspi_probe then
annotate omap2_mcspi_master_setup with a matching annotation.
The fix is obviously to mark the omap2_mcspi_master_setup function as

If a seccomp filter program is installed, older static binaries and
distributions with older libc implementations (glibc 2.13 and earlier)
that rely on vsyscall use will be terminated regardless of the filter
program policy when executing time, gettimeofday, or getcpu. This is
only the case when vsyscall emulation is in use (vsyscall=emulate is the
default).
This patch emulates system call entry inside a vsyscall=emulate by
populating regs->ax and regs->orig_ax with the system call number prior
to calling into seccomp such that all seccomp-dependencies function
normally. Additionally, system call return behavior is emulated in line
with other vsyscall entrypoints for the trace/trap cases.
