There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.Signed-off-by: Jean Delvare

only 3 bytes - pwm_config[3] is out of range.Since this code path is never called with ix == 3 (the device has no PWM4

On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt. This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the
memorized logical state, in effect bringing back the accelerometer and
backlight to the state prior to suspend. Works for both suspend to ram
and hibernation. The patch has zero effect on the running state.Signed-off-by: Henrik Rydberg

Enable the coretemp driver on an Intel Atom.
I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load). Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.Cc: Arjan van de Ven

This driver adds support for the hardware monitoring features of
the WM831x PMICs to the hwmon API. Monitoring is provided for
the system voltages supported natively by the WM831x, the chip
temperature, the battery temperature and the auxiliary inputs
of the WM831x.Currently no alarms are supported, though digital comparators on
the WM831x devices would allow these to be provided.Since the auxiliary and battery temperature input scaling depends
on the system configuration the value is reported as a voltage to
userspace.Signed-off-by: Mark Brown

The Winbond/Nuvoton WPCD377I is the reduced version of a Super-I/O
which emulates the National Semiconductor LM96000 hardware monitoring
chips, but without the hardware monitoring part. Instead of plain
disabling the emulation, the vendor left the emulated chip visible,
but all monitored values are always zero. This is rather confusing for
the users. So detect this case and refuse to bind to such fake chips.This fixes lm-sensors ticket #2182:

Now that we have ACPI-based hardware monitoring drivers, and we will
start telling users to use them instead of native drivers when I/O
resources conflict, I think it would be good to clearly mark ACPI
drivers as such in Kconfig.Also, in the case of monolithic kernels, I think the ACPI drivers
should take precedence over native drivers, so they should be listed
first in Makefile.Signed-off-by: Jean Delvare

We had a report about a mainboard for AMD family 0Fh processors not
routing the 6th VID pin from the CPU to the hardware monitoring chip.While the vendor should have wired the pin (or, failing that, should
have hardwired it to level high rather than low), the fact is that
none of these processors are currently known to operate at the lower
voltage levels which require the 6th VID pin. So, as a practical
workaround, I propose to ignore the 6th VID pin for these CPUs.If this decision ever causes problems, we'll reconsider.

Most known Abit motherboards have unique uguru chip IDs. However,
some "refresh" boards keep the same chip ID but have a different
DMI string. As our DMI board string matching is (necessarily)
strict, some boards were failing DMI detection, and as the old
probe method was also failing, the driver would not load.The only known boards affected by this problem are the IP35 Pro XE
(vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to
relax the match criteria, as some boards (e.g. the AB9 Quad GT)
have different uguru chip IDs.This patch replaces the dmi_name string with a NULL terminated
array of strings to be matched per uguru chip ID. It has been
compile and runtime tested (thanks Rune).References: https://bugs.launchpad.net/bugs/298798
