Arnd said in another patch:
"As far as I can tell, this driver must have produced this
error for as long as it has been merged into the mainline kernel, but
it was never part of the normal build tests:
drivers/i2c/busses/i2c-nuc900.c: In function 'nuc900_i2c_probe':
drivers/i2c/busses/i2c-nuc900.c:601:17: error: request for member
'apbfreq' in something not a structure or union
ret = (i2c->clk.apbfreq)/(pdata->bus_freq * 5) - 1;
^
This is an attempt to get the driver to build and possibly
work correctly, although I do wonder whether we should just
remove it, as it has clearly never worked."
I agree with removing it since nobody showed interest in Arnd's fixup
patch.

Since IMX serial SOCs support low bus freq mode, some clocks freq
may change to save power. I2C needs to check the clock source and
update the divider.
For example:
i.MX6SL I2C clk is from IPG_PERCLK which is sourced from IPG_CLK.
Under normal operation, IPG_CLK is 66MHz, ipg_perclk is at 22MHz.
In low bus freq mode, IPG_CLK is at 12MHz and IPG_PERCLK is down
to 4MHz. So the I2C driver must update the divider register for
each transaction when the current IPG_PERCLK is not equal to the
clock of previous transaction.

Test i2c device Maxim max44009, datasheet is located at:
http://www.maximintegrated.com/datasheet/index.mvp/id/7175
The max44009 support repeat operation like:
read -> repeat restart -> read/write
The current i2c imx host controller driver don't support this
operation that causes i2c bus hang due to "MTX" is cleared in
.i2c_imx_read(). If "read" is the last message there have no problem,
so the current driver supports all SMbus operation like:
write -> repeat restart -> read/write
IMX i2c controller for master receiver has some limitation:
- If it is the last byte for one operation, it must generate STOP
signal before read I2DR to prevent controller from generating another
clock cycle.
- If it is the last byte in the read, and then do repeat restart, it must
set "MTX" before read I2DR to prevent controller from generating another
extra clock cycle.
The patch is to fix the issue.

We should always check if the bus is free, independently if it is a read

HSI2C module on Exynos5260 differs from current modules in
following ways:
1. HSI2C on Exynos5260 has fifo_depth of 16bytes
2. Module needs to be reset as a part of init sequence.
Hence, Following changes are involved.
1. Add a new compatible string and Updates the Documentation dt bindings.
2. Introduce a variant struct to support the changes in H/W
3. Reset the module during init. Thus, bringing the module back
to default state irrespective of what firmware did with it.

For !CONFIG_PM_RUNTIME, the device were never put back into active
state while resuming.
For CONFIG_PM_RUNTIME, we blindly trusted the device to be inactive
while we were about to handle it at suspend late, which is just too
optimistic.
Even if the driver uses pm_runtime_put_sync() after each tranfer to
return it's runtime PM resources, there are no guarantees this will
actually mean the device will inactivated. The reason is that the PM
core will prevent runtime suspend during system suspend, and thus when
a transfer occurs during the early phases of system suspend the device
will be kept active after the transfer.
To handle both issues above, use pm_runtime_force_suspend|resume() from
the system suspend|resume callbacks.

Pull ACPI and power management fixes from Rafael Wysocki:
"Still fixing regressions (partly by reverting commits that broke
things for people), fixing other stable-candidate bugs and adding some
blacklist entries for ACPI video and _OSI.
Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
fix for an ACPI-related regression in TPM (introduced in 3.14), a
revert of the ACPI AC driver conversion in 3.13 that went wrong for an
unknown reason, two reverts of commits that attempted to remove an old
user space interface in /proc and broke some utilities, in 3.13 too, a
fix for a CPU hotplug bug in the ACPI processor driver (stable
material), two (stable candidate) fixes for intel_pstate and a few new
blacklist entries, mostly for systems that shipped with Windows 8.
Specifics:
- ACPICA fix for a stale pointer access introduced by a recent commit
in the XSDT validation code from Lv Zheng.
- ACPICA fix for the default value of the command line switch to
favor 32-bit FADT addresses (in case there's a conflict between a
64-bit and a 32-bit address). The previous default was that the
32-bit version would take precedence and we tried to change it to
the other way around and it didn't work. From Lv Zheng.
- A TPM commit related to ACPI _DSM in 3.14 caused the driver to
refuse to load if a specific _DSM was missing and that broke resume
from system suspend on Chromebooks that require the TPM hardware to
be restored to a working state during resume by the OS. Restore
the old behavior to load the driver if the _DSM in question is not
present, but prevent it from using the feature the _DSM is for.
- ACPI AC driver conversion in 3.13 broke thermal management on at
least one machine and has to be reverted. From Guenter Roeck.
- Two reverts of 3.13 commits that attempted to remove the old ACPI
battery interface in /proc, but turned out to break some utilities
still using that interface. From Lan Tianyu.
- ACPI processor driver fix to prevent acpi_processor_add() from
modifying the CPU device's .offline field which leads to breakage
if the initial online of the CPU fails. From Igor Mammedov.
- Two intel_pstate fixes, one to take a BayTrail documentation update
into account and one to avoid forcing the maximum P-state on init
which causes CPU PM trouble on systems with P-states coordination
when one of the CPU cores is initialized after an offline/online
cycle triggered by user space. Both stable candidates, from Dirk
Brandewie.
- Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
from Aaron Lu.
- Two new ACPI video blacklist entries for machines shipping with
Win8 that need to use native backlight so that it can be controlled
in a usual way (which doesn't work otherwise due bugs in the ACPI

Pull device mapper fixes from Mike Snitzer:
"A dm-crypt fix for a cpu hotplug crash that switches from using
per-cpu data to a mempool allocation (which offers allocation with cpu
locality, and there is no inter-cpu communication on slab allocation).
A couple dm-thinp stable fixes to address "out-of-data-space" issues.
A dm-multipath fix for a LOCKDEP warning introduced in 3.15-rc1"
* tag 'dm-3.15-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm mpath: fix lock order inconsistency in multipath_ioctl
dm thin: add timeout to stop out-of-data-space mode holding IO forever
dm thin: allow metadata commit if pool is in PM_OUT_OF_DATA_SPACE mode
dm crypt: fix cpu hotplug crash by removing per-cpu structure

"Drivercore bugfixes for v3.15
This branch contains bug fixes important to get into v3.15. There is
a fix for modifying properties seen during early boot, a fix for an
incorrect prototype when CONFIG_OF=n, and a couple of corrections to
device tree memory nodes on a few platforms"

"MIPS fixes for various loose ends:
- Fix workarounds for R4000 erratum.
- Patch up DEC, Siemens-Nixdorf and Loongson hardware support.

scripts.
