Guenter Roeck e1e081a7e3 hwmon: (pmbus) Simplify memory allocation for sensor attributes
Since memory is now allocated with dev_ functions, we no longer need to keep
track of allocated memory. Sensor memory allocation can therefore be
simplified significantly.

Guenter Roeck 663834f3b7 hwmon: (pmbus) Improve boolean handling
Boolean handling depends on storing the sensor data index in sensor_device_attr
as part of the index variable. This limits the number of sensor attributes to
256, and means the sensor sequence number actually has to be maintained to be
able to access sensor data from boolean functions.

Rework the code to store sensor pointers in the pmbus_boolean data structure
directly. With this approach, the number of supportable sensors is now
unlimited.

Vivien Didelot 412e29c135 hwmon: (sht15) check GPIO directions
Without this patch, the SHT15 driver may fail silently with a
non-bidirectional data line and/or an input-only clock line.

This patch checks the return value of gpio_direction_* function calls
and returns the error code (if any) to the caller. If an error occurs in
the read work function (work_funct_t), we wake the queue up directly
without updating the data->state flag, to notice the waiter of the I/O
error.

The patch also makes minor cleanups: s/error_ret/unlock for some labels
and uses devm_gpio_request_one() for the clock line.

Chris Verges 0602934f30 hwmon: (lm73} Detect and report i2c bus errors
If an LM73 device does not exist on an I2C bus, attempts to communicate
with the device result in an error code returned from the i2c read/write
functions.  The current lm73 driver casts that return value from a s32
type to a s16 type, then converts it to a temperature in celsius.
Because negative temperatures are valid, it is difficult to distinguish
between an error code printed to the response buffer and a negative
temperature recorded by the sensor.

The solution is to evaluate the return value from the i2c functions
before performing any temperature calculations.  If the i2c function did
not succeed, the error code should be passed back through the virtual
file system layer instead of being printed into the response buffer.

Before:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   -46

After:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   cat: read error: No such device or address

The smatch static code analyzer complains:

drivers/hwmon/w83627ehf.c:911 w83627ehf_update_device() error: buffer overflow 'W83627EHF_REG_TEMP_OFFSET' 3 <= 8
drivers/hwmon/w83627ehf.c:909 w83627ehf_update_device() error: buffer overflow 'data->temp_offset' 3 <= 8

drivers/hwmon/w83627ehf.c:2673 w83627ehf_resume() error: buffer overflow 'data->temp_offset' 3 <= 8

A deeper analysis of the code shows that these are false positives, as
only the lower 3 bits of data->have_temp_offset can be set so the
write is never attempted with i >= 3. However this shows that the code
isn't very robust and future changes could easily introduce a buffer
overflow. So let's add a safety check to prevent that and make smatch
happy.

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.

 "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.

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.

Amit Daniel Kachhap c48cbba6fe hwmon: exynos4: move thermal sensor driver to driver/thermal directory
This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.

coretemp_init loops with for_each_online_cpu, adding platform_devices
and sysfs interfaces, then calls register_hotcpu_notifier.  There is a
race if a CPU is offlined or onlined after the loop, but before
register_hotcpu_notifier.  The race might result in the absence of a
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
CPU might offline and a device for an offline CPU will exist for 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.

Henrik Rydberg e30bca1257 hwmon: (applesmc) Ignore some temperature registers
Not all sensors in the T range are useful temperatures.  This patch

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.

Guenter Roeck bbc8a569ae hwmon: (w83781d) Fix compile warning
The following compile warning may be seen if the driver is compiled with
-Wuninitialized:

drivers/hwmon/w83781d.c: warning: 'sc_addr[1]' may be used uninitialized in this
function [-Wuninitialized]

While this is a false positive, it is annoying in nightly builds, and may help
to conceal real problems. The current code is quite tricky, and and it is easy
to rearrage the code to make the warning disappear. So fix it.

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.

The patch was originally written by adamski99 (ubuntuforums.org) and
later tested by janhouse (bbs.archlinux.org).
