Pull rockchip fixes from Heiko Stuebner:
Fixes for wrong register offsets in both rk3036 and rk3368.
Also rename the external input for the emac on rk3036, which
should still be ok to do, as that binding was only introduced
during this merge-window.

My previous patch fixed some warnings about printing a couple
of variables that are always uninitialized in quadfs_pll_fs660c32_set_rate(),
but I now got a warning that only shows up in some configurations (i.e.
without gcc -Os) about the params.ndiv being used uninitialized in the
error case:
drivers/clk/st/clkgen-fsyn.c: In function 'quadfs_pll_fs660c32_set_rate':
drivers/clk/st/clkgen-fsyn.c:584:75: warning: 'params.ndiv' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/clk/st/clkgen-fsyn.c:574:16: note: 'params.ndiv' was declared here
This changes the error handling so we bail for invalid arguments rather
than continuing with uninitialized data.

The size of unsigned long on 64-bit architectures is equal to the
size of u64, so this check is impossible there. This throws off
static checkers:
drivers/clk/clk-axi-clkgen.c:331 axi_clkgen_recalc_rate() warn:
impossible condition '(tmp > (~0)) => (0-u64max > u64max)'
Let's change this code to use min_t() instead so that we
get the same effect on architectures where sizeof(unsigned long)
doesn't equal sizeof(u64).

Version 1 of the axi-clkgen core has not been used in new designs for over
two years now. This is a soft peripheral used in FPGAs and anybody who has
updated their kernel to the latest version will also have updated the
bitstream containing the clock generator. So it should be safe to drop
support for this now.

of_match_device could return NULL, and so cause a NULL pointer
dereference later.
Even if the probability of this case is very low, fixing it made
static analyzers happy.
Solving this with of_device_get_match_data made also code simplier.

The definition of s2mps11_name is meant to resolve the name of a
given clock. Remove it because the clocks have the same name we
can get it directly from the s2mps11_clks_init structure.
While in the probe function the s2mps11_clks is used only to
iterate through the s2mps11_clks. The naming itself brings
confusion and the readability does not improve much.

The clk_table and clk_data are declared static. The clk_table
contains the three clock data structures belonging to the s2mps11
driver. In the probe function it gets stored into clk_data.

clk_data, itself, is also declared static. Declare locally it
and allocate it inside the probe function, as it is not used
anywhere else.

The driver allocates three structures, s2mpsxx_clk_init, for
three different clock types (s2mps11, s2mps13 and s2mps14). They
are quite similar but they differ only by the name. Only one of
these structures is used, while the others lie unused in the
memory.
The clock's name, though, is not such a meaningful information
and by assigning the same name to the initial data we can avoid
over allocation. The common name chosen will be s2mps11,
coherently with the device driver name, instead of the clock
device.
Therefore, remove the structures associated to s2mps13 and
s2mps14 and use only the one referred to s2mps11 for all kind of
clocks.

Commit e6d5e7d90be9 ("clk-divider: Fix READ_ONLY when divider > 1") removed
the special ops struct for read-only clocks and instead opted to handle
them inside the regular ops.
On the rk3368 this results in breakage as aclkm now gets set a value.
While it is the same divider value, the A53 core still doesn't like it,
which can result in the cpu ending up in a hang.
The reason being that "ACLKENMasserts one clock cycle before the rising
edge of ACLKM" and the clock should only be touched when STANDBYWFIL2
is asserted.
To fix this, reintroduce the read-only ops but do include the round_rate
callback. That way no writes that may be unsafe are done to the divider
register in any case.
The Rockchip use of the clk_divider_ops is adapted to this split again,
as is the nxp, lpc18xx-ccu driver that was included since the original
commit. On lpc18xx-ccu the divider seems to always be read-only
so only uses the new ops now.

Most PLL's don't actually have LOCK_ENABLE bits. However, most PLL's
also had that flag set, which meant that the clk code was trying to
enable locks, and inadvertantly flipping bits in other fields.
For PLLM, ensure the correct register is used for the misc_register.
PLL_MISC0 contains the EN_LCKDET bit which should be used for enabling
the lock, and PLLM_MISC1 shouldn't be used at all.
Lastly, remove some of the settings which would point to the EN_LCKDET
bits for some PLLs. There is no need to enable the locks, and that is
done as part of the set_defaults logic already.

This adds support for the interrupt controller present on PIC32 class
devices. It handles all internal and external interrupts. This controller
exists outside of the CPU core and is the arbitrator of all interrupts
(including interrupts from the CPU itself) before they are presented to
the CPU.
The following features are supported:
- DT properties for EVIC and for devices/peripherals that use interrupt lines
- Persistent and non-persistent interrupt handling
- irqdomain and generic chip support
- Configuration of external interrupt edge polarity

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC support for Tegra platforms from Olof Johansson:
"Here's a single-SoC topic branch that we've staged separately. Mainly
because it was hard to sort the branch contents in a way that fit our
existing branches due to some refactorings.
The code has been in -next for quite a while, but we staged it in
arm-soc a bit late, which is why we've kept it separate from the other
updates and are sending it separately here"

There are many locations that do
if (memory_was_allocated_by_vmalloc)
vfree(ptr);
else
kfree(ptr);
but kvfree() can handle both kmalloc()ed memory and vmalloc()ed memory
using is_vmalloc_addr(). Unless callers have special reasons, we can
replace this branch with kvfree(). Please check and reply if you found
problems.
