The interrupt line used for the watchdog is 12, according to the official
Intel Edison BSP code.
And indeed after fixing it we start getting an interrupt and thus the
watchdog starts working again:

Legacy RTC requires interrupt line 8 to be dedicated for it. On
Intel MID platforms the legacy PIC is absent and in order to make RTC
work we need to allocate interrupt separately.
Current solution brought by commit de1c2540aa4f does it in a wrong place,
and since it's done unconditionally for all x86 devices, some of them,
e.g. PNP based, might get it wrong because they execute the MID specific
code due to x86_platform.legacy.rtc flag being set.
Move intel_mid_legacy_rtc_init() to its own module and call it before x86 RTC
CMOS initialization.

The Intel Mid goes in and creates a I2C device for the
MPU3050 if the input driver for MPU-3050 is activated.
As of commit:
3904b28efb2c ("iio: gyro: Add driver for the MPU-3050 gyroscope")
.. there is a proper and fully featured IIO driver for this
device, so deprecate the use of the incomplete input driver
by augmenting the device population code to react to the
presence of the IIO driver's Kconfig symbol instead.

Pull timer updates from Thomas Gleixner:
"This is the last functional update from the tip tree for 4.10. It got
delayed due to a newly reported and anlyzed variant of BIOS bug and
the resulting wreckage:
- Seperation of TSC being marked realiable and the fact that the
platform provides the TSC frequency via CPUID/MSRs and making use
for it for GOLDMONT.
- TSC adjust MSR validation and sanitizing:
The TSC adjust MSR contains the offset to the hardware counter. The
sum of the adjust MSR and the counter is the TSC value which is
read via RDTSC.
On at least two machines from different vendors the BIOS sets the
TSC adjust MSR to negative values. This happens on cold and warm
boot. While on cold boot the offset is a few milliseconds, on warm
boot it basically compensates the power on time of the system. The
BIOSes are not even using the adjust MSR to set all CPUs in the
package to the same offset. The offsets are different which renders
the TSC unusable,
What's worse is that the TSC deadline timer has a HW feature^Wbug.
It malfunctions when the TSC adjust value is negative or greater
equal 0x80000000 resulting in silent boot failures, hard lockups or
non firing timers. This looks like some hardware internal 32/64bit
issue with a sign extension problem. Intel has been silent so far
on the issue.
The update contains sanity checks and keeps the adjust register
within working limits and in sync on the package.
As it looks like this disease is spreading via BIOS crapware, we
need to address this urgently as the boot failures are hard to
debug for users"

TSC on Intel Atom SoCs capable of determining TSC frequency by MSR is
reliable and the frequency is known (provided by HW).
On these platforms PIT/HPET is generally not available so calibration won't
work at all and there is no other clocksource to act as a watchdog for the
TSC, so we have no other choice than to trust it.
Set both X86_FEATURE_TSC_KNOWN_FREQ and X86_FEATURE_TSC_RELIABLE flags to
make sure the calibration is skipped and no watchdog is required.

Watchdog device in Intel Tangier relies on SCU to be present. It uses the SCU
IPC channel to send commands and receive responses. If watchdog driver is
initialized quite before SCU and a command has been sent the result is always
an error like the following:
intel_mid_wdt: Error stopping watchdog: 0xffffffed
Register watchdog device whne SCU is ready to avoid described issue.

Commit cc7cc02bada8 ("PCI: Query platform firmware for device power
state") augmented struct pci_platform_pm_ops with a ->get_state hook and
implemented it for acpi_pci_platform_pm, the only pci_platform_pm_ops
existing till v4.7.
However v4.8 introduced another pci_platform_pm_ops for Intel Mobile
Internet Devices with commit 5823d0893ec2 ("x86/platform/intel-mid: Add
Power Management Unit driver"). It is missing the ->get_state hook,
which is fatal since pci_set_platform_pm() enforces its presence. Andy
Shevchenko reports that without the present commit, such a device
"crashes without even a character printed out on serial console and
reboots (since watchdog)".
Retrofit mid_pci_platform_pm with the missing callback to fix the
breakage.

immediately.
This appears to be a safer approach based on the documentation.

Drivers should not really include stuff from asm-generic directly,
and the PC-style cmos rtc driver does this in order to reuse the
mc146818 implementation of get_rtc_time/set_rtc_time rather than
the architecture specific one for the architecture it gets built for.
To make it more obvious what is going on, this moves and renames the
two functions into include/linux/mc146818rtc.h, which holds the
other mc146818 specific code. Ideally it would be in a .c file,
but that would require extra infrastructure as the functions are
called by multiple drivers with conflicting dependencies.
With this change, the asm-generic/rtc.h header also becomes much
more generic, so it can be reused more easily across any architecture
that still relies on the genrtc driver.
The only caller of the internal __get_rtc_time/__set_rtc_time
functions is in arch/alpha/kernel/rtc.c, and we just change those
over to the new naming.

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. The advantage
in doing so is that module.h itself sources about 15 other headers;
adding significantly to what we feed cpp, and it can obscure what
headers we are effectively using.
Since module.h was the source for init.h (for __init) and for
export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance
for the presence of either and replace as needed.
One module.h was converted to moduleparam.h since the file had
multiple module_param() in it, and another file had an instance of
MODULE_DEVICE_TABLE deleted, since that is a no-op when builtin.
Finally, the 32 bit build coverage of olpc_ofw revealed a couple
implicit includes, which were pretty self evident to fix based on
what gcc was complaining about.

Intel MID platforms are using explicitly defined regulators.
Let the regulator core know that we do not have any additional
regulators left. This lets it substitute unprovided regulators with
dummy ones.
Without this change when CONFIG_REGULATOR=y the USB driver fails on getting
"vbus" regulator and SDHCI can't get "vmmc" and "vqmmc" regulators either.

Intel Penwell is one of the first SoCs in Intel MID series. It has slightly
older version of PWRMU IP, though it is compatible with one found on Intel
Tangier. Since we are not using (yet) any advanced stuff in the driver we may
safely re-use what it's done for Intel Tangier for now.
Extend PWRMU driver to support Intel Penwell by adding PCI ID and re-using
existing ->set_initial_state() function.

Pull module_init replacement part one from Paul Gortmaker:
"Replace module_init with equivalent device_initcall in non modules.
This series of commits converts non-modular code that is using the
module_init() call to hook itself into the system to instead use
device_initcall().
The conversion is a runtime no-op, since module_init actually becomes
__initcall in the non-modular case, and that in turn gets mapped onto
device_initcall. A couple files show a larger negative diffstat,
representing ones that had a module_exit function that we remove here
vs previously relying on the linker to dispose of it.
We make this conversion now, so that we can relocate module_init from
init.h into module.h in the future.
The files changed here are just limited to those that would otherwise
have to add module.h to obviously non-modular code, in order to avoid
a compile fail, as testing has shown"

The X86_INTEL_MID option is bool, and hence this code is either
present or absent. It will never be modular, so using
module_init as an alias for __initcall is rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
