Giel van Schijndel 7721fea3d0 hwmon: f71882fg: add support for the Fintek F71808E
Allow device probing to recognise the Fintek F71808E.

Sysfs interface:
 * Fan/pwm control is the same as for F71889FG
 * Temperature and voltage sensor handling is largely the same as for
   the F71889FG
  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to
    what in7_input refers for F71889FG)

For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.

Fenghua Yu cb84b19474 x86, hwmon: Package Level Thermal/Power: pkgtemp hwmon driver
This patch adds a hwmon driver for package level thermal control. The driver
dumps package level thermal information through sysfs interface so that upper
level application (e.g. lm_sensor) can retrive the information.

Instead of having the package level hwmon code in coretemp, I write a seperate
driver pkgtemp because:

First, package level thermal sensors include not only sensors for each core,
but also sensors for uncore, memory controller or other components in the
package. Logically it will be clear to have a seperate hwmon driver for package
level hwmon to monitor wider range of sensors in a package. Merging package
thermal driver into core thermal driver doesn't make sense and may mislead.

Secondly, merging the two drivers together may cause coding mess. It's easier
to include various package level sensors info if more sensor information is
implemented. Coretemp code needs to consider a lot of legacy machine cases.
Pkgtemp code only considers platform starting from Sandy Bridge.

On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp:

pkgtemp-isa-0000
Adapter: ISA adapter
physical id 0: +33.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0000

Both of_bus_type and of_platform_bus_type are just #define aliases

switches to the of_register_platform_driver()/of_unregister_platform_driver()

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

Jean Delvare 436cad2a41 hwmon: (it87) Fix in7 on IT8720F
The IT8720F has no VIN7 pin, so VCCH should always be routed
internally to VIN7 with an internal divider. Curiously, there still
is a configuration bit to control this, which means it can be set
incorrectly. And even more curiously, many boards out there are
improperly configured, even though the IT8720F datasheet claims that
the internal routing of VCCH to VIN7 is the default setting. So we
force the internal routing in this case.

It turns out that all boards with the wrong setting are from Gigabyte,
so I suspect a BIOS bug. But it's easy enough to workaround in the
driver, so let's do it.

Jean Delvare cd4de21f7e hwmon: (k8temp) Bypass core swapping on single-core processors
Commit a2e066bba2 introduced core
swapping for CPU models 64 and later. I recently had a report about
a Sempron 3200+, model 95, for which this patch broke temperature
reading. It happens that this is a single-core processor, so the
effect of the swapping was to read a temperature value for a core
that didn't exist, leading to an incorrect value (-49 degrees C.)

Disabling core swapping on singe-core processors should fix this.

Additional comment from Andreas:

The BKDG says

  Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit
  selects the CPU whose temperature is reported in the CurTemp
  field. This bit only applies to dual core processors. For
  single core processors CPU0 Thermal Sensor is always selected.

k8temp_probe() correctly detected that SEL_CORE can't be used on single
core CPU. Thus k8temp did never update the temperature values stored
in temp[1][x] and -49 degrees was reported. For single core CPUs we
must use the values read into temp[0][x].

Wolfram Sang fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

Jean Delvare 87c33daadb hwmon: (adm1031) Allow setting update rate
Based on earlier work by Ira W. Snyder.

The adm1031 chip is capable of using a runtime configurable sampling rate,
using the fan filter register. Add support for reading and setting the
update rate via sysfs.

Ira W. Snyder 8c3c7a256f hwmon: (lm90) Use programmed update rate
The lm90 driver programs the sensor chip to update its readings at 2 Hz
(500 ms between readings). However, the driver only does reads from the
chip at intervals of 2 * HZ (2000 ms between readings). Change the driver
update rate to the programmed update rate.

Jean Delvare 70dd6beac0 hwmon: (asus_atk0110) Don't load if ACPI resources aren't enforced
When the user passes the kernel parameter acpi_enforce_resources=lax,
the ACPI resources are no longer protected, so a native driver can
make use of them. In that case, we do not want the asus_atk0110 to be
loaded. Unfortunately, this driver loads automatically due to its
MODULE_DEVICE_TABLE, so the user ends up with two drivers loaded for
the same device - this is bad.

So I suggest that we prevent the asus_atk0110 driver from loading if
acpi_enforce_resources=lax.

Samu Onkalo 6d94d40810 lis3: interrupt handlers for 8bit wakeup and click events
Content for the 8bit device threaded interrupt handlers.  Depending on the
interrupt line and chip configuration, either click or wakeup / freefall
handler is called.  In case of click, BTN_ event is sent via input device.
 In case of wakeup or freefall, input device ABS_ events are updated
immediatelly.

It is still possible to configure interrupt line 1 for fast freefall
detection and use the second line either for click or threshold based
interrupts.  Or both lines can be used for click / threshold interrupts.

Polled input device can be set to stopped state and still get coordinate
updates via input device using interrupt based method.  Polled mode and
interrupt mode can also be used parallel.

BTN_ events are remapped based on existing axis remapping information.

Samu Onkalo 342c5f1281 lis3: introduce platform data for second ff / wu unit
8 bit device has two wakeup / free fall units.  It was not possible to
configure the second unit.  This patch introduces configuration entry to
the platform data and also corresponding changes to the 8 bit setup
function.

High pass filters were enabled by default.  Patch introduces configuration
option for high pass filter cut off frequency and also possibility to
disable or enable the filter via platform data.  Since the control is a
new one and default state was filter enabled, new option is used to
disable the filter.  This way old platform data is still compatible with
the change.
