Jean Delvare 8f3c7c547d hwmon: (w83627hf) Don't touch nonexistent I2C address registers
Only the W83627HF could be accessed through I2C. All other supported
chips are LPC-only, so they do not have I2C address registers. Don't
write to nonexistent or reserved registers on these chips.

Jean Delvare 275b7d6ebe hwmon: (w83627hf) Add support for suspend
On suspend some register values are lost, most notably the Value RAM
areas but also other limits. Restore them on resume. On top of that,
some fixups are needed to work around BIOS bugs, in particular when
the BIOS omits running the same initialization sequence on resume
that it does after boot. In that case we have to carry initialization
over suspend.

Linus Torvalds cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

Guenter Roeck 72cbdddcc1 hwmon: (coretemp) Drop dependency on PCI for TjMax detection on Atom CPUs
So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for
Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping
(x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs
with TjMax of 100 degrees C. This was verified by checking the output of
/proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx).

Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not
supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90
degrees C, except for E6xxT models which have a TjMax of 110 degrees C.
E6xxT CPUs can however not be detected by software.

Calculate TjMax for Atom CPUs as follows. Note that the listed values are not
correct in some cases (230, 330). tjmax_table is used for those to override
the default values.

ID	Stepping	TjMax		Models
0x1c	10		100		D4xx, N4xx, D5xx, N5xx
0x1c	not 10		90		Z5xx, N2xx, 230, 330, others
0x26	-		90		Atom Tunnel Creek (Exx),
					Lincroft (Z6xx)
0x27	-		90		Atom Medfield (Z2460)
0x36	-		100		Atom Cedar Trail (N2xxx, D2xxx)

Also drop the module dependency on PCI.

avoiding function prototypes and using convenient macros such as

Linus Torvalds 5e090ed7af ARM: soc: late platform updates
This branch contains updates to OMAP and Marvell platforms (kirkwood,
 dove, mvebu) that came in after we had done the big multiplatform merges,
 so they were kept separate from the rest, and not separated into the
 traditional topics of cleanup/driver/platform features.
 
 For OMAP, the updates are:
 - Runtime PM conversions for the GPMC and RNG IP blocks
 - Preparation patches for the OMAP common clock framework conversion
 - clkdev alias additions required by other drivers
 - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
 - OMAP hwmod code and data improvements
 - Preparation patches for the IOMMU runtime PM conversion
 - Preparation patches for OMAP4 full-chip retention support
 
 For Kirkwood/Dove/mvebu:
 
 - New driver for "address decoder controller" for mvebu, which
   is a piece of hardware that configures addressable devices and
   peripherals. First user is the boot rom aperture on armada XP since
   it is needed for SMP support.
 - New device tree bindings for peripherals such as gpio-fan, iconnect
   nand, mv_cesa and the above address decoder controller.
 - Some defconfig updates, mostly to enable new DT boards and a few drivers.
 - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
 - New clean gpio driver for mvebu

Linus Torvalds 9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by

platform_device+sysfs interface for an online CPU, or the presence of
a platform_device+sysfs interface for an offline CPU.  A similar race
occurs during coretemp_exit, after the module calls
unregister_hotcpu_notifier, but before it unregisters all devices, a

Guenter Roeck 080b98e9ab hwmon: (ina2xx) Fix word size register read and write operations
The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word
operations from chip to host byte order. However, the data passed from and to
the SMBus word API functions is in host byte order, not in chip byte order.
Conversion should therefore use swab16 instead of be16 to change the byte order.

Replace driver internal word conversion functions with SMBus API functions to
solve the problem.

Henrik Rydberg 829917cd72 hwmon: (applesmc) Decode and act on read/write status codes
The behavior of the SMC has changed several times over the years,
causing read failures in the driver. It seems the problem can be
explained by a shift in SMC speed combined with improper action on
status codes.

We should first wait for the SMC to settle, which was the most
frequent response on the old slow machines. Then, if the SMC is busy,
we need to try again later by resending the command. This was the most
likely response until 2012. Now, with a shorter wait time, we are
again most likely to poll while the SMC is settling, and as a result
we see high failure rates on many old and new models.

With the distinction between busy and failure, we can also wait longer
before retrying, without sacrificing speed.  This seems to bring
failures down to virtually zero on all models.

Restoring the configuration register on device removal has the side
effect of also resetting the hysteresis value. This is inconsistent as
the other limits are not reset, only hysteresis. So, following the

restoring the configuration register.

Henrik Rydberg b6e5122f09 hwmon: (applesmc) Allow negative temperature values
There are many userland reports of sensors with unreasonably small and
large temperatures. There seem to be several reasons for this:

Firstly, the major sensor type (sp78) is actually a signed number.
This explains why some sensors show very small or large values - they
are in fact all small, but of different sign.

Secondly, the other sensor type (1-hex) is not properly understood; it
may be that it is not a temperature after all.

Thirdly, some sensors are differential in nature, showing changes over
time rather than absolute numbers.  This explains why those values are
small and of varying sign.

This patch interprets the sp78 type as signed short, but keeps the
original scaling. For other types, -EINVAL is returned, since the
nature of those sensors is unknown.

Henrik Rydberg a332bf9a65 hwmon: (applesmc) Shorten minimum wait time
The 2012 series of MacBooks have a faster SMC, and the current driver
timings do not work at all. Tests show that decreasing the minimum
wait time, from 64 us to 16 us, works well. Since this is still larger
than the original minimum of 10 us used before 2008, there is nothing
inherently problematic with changing it. The fail frequency on older
machines seems to increase slightly, but not enough to be noticeable.

Tested on MBA11, MBA31, MBA5,2, MBP9,2.

I no longer have a mailbox at smsc.com, and I've had two reports
that that email address now bounces from people trying to
contact me.  This patch updates all references to that invalid
address to one that I can be contacted on more permanently.

This patch also updates the maintainer status to reflect
the fact I'm no longer directly paid to maintain these drivers.
