Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.
Conversion done using the script at:

The bandgap sensor can be idled when the processor is too, but it
isn't currently being done, so the power consumption of OMAP3
boards can elevated if the bangap sensor is enabled.
This patch attempts to use some additional power management
to idle the clock to the bandgap when not needed.

sun50i_h6_ths_calibrate
For sun50i_h6_ths_calibrate(), the data read from nvmem needs a round of
calculation. On the other hand, the newer SOC may store other data in
the space other than 12bit sensor data. Add mask operation to read data
to avoid conversion error.

to confirm by using imok sysfs entry.

The user-after-free bug in thermal_zone_device_unregister() is reported by
KASAN. It happens because struct thermal_zone_device is released during of
device_unregister() invocation, and hence the "tz" variable shouldn't be

We can sometimes get bogus thermal shutdowns on omap4430 at least with
droid4 running idle with a battery charger connected:
thermal thermal_zone0: critical temperature reached (143 C), shutting down
Dumping out the register values shows we can occasionally get a 0x7f value
that is outside the TRM listed values in the ADC conversion table. And then
we get a normal value when reading again after that. Reading the register
multiple times does not seem help avoiding the bogus values as they stay
until the next sample is ready.
Looking at the TRM chapter "18.4.10.2.3 ADC Codes Versus Temperature", we
should have values from 13 to 107 listed with a total of 95 values. But
looking at the omap4430_adc_to_temp array, the values are off, and the
end values are missing. And it seems that the 4430 ADC table is similar
to omap3630 rather than omap4460.
Let's fix the issue by using values based on the omap3630 table and just
ignoring invalid values. Compared to the 4430 TRM, the omap3630 table has
the missing values added while the TRM table only shows every second
value.
Note that sometimes the ADC register values within the valid table can
also be way off for about 1 out of 10 values. But it seems that those
just show about 25 C too low values rather than too high values. So those
do not cause a bogus thermal shutdown.

We just don't do that. "default y" is for things that are needed for
compatibility (when an old feature is made unconditional), or for things
that are basically part of the infrastructure of a platform.
And it can possibly be used for questions that don't enable code on
their own, but are used to enable or disable a whole slew of other
questions.
A new feature that people aren't using is never 'default y', unless it
cures cancer or ends world hunger.

It is known that Mediatek owns two thermal systems, which only differ
in the way of reading calibration data and converting temperature.
MT8173, MT8183, MT2701 and MT2712 belongs to version 1 thermal
system, and MT7622 belongs to version 2.
In order to handle both systems, the suffix _V1 is appended to the
current code, and then the second patch will add _V2 functions with
the same purpose but different implementation.

The TSENS integrated on MSM8939 is a v0_1 device with 10 sensors.
Different from its predecessor MSM8916, where 'calib_sel' bits sit in
separate qfprom word, MSM8939 has 'cailb' and 'calib_sel' bits mixed and
spread on discrete offsets. That's why all qfprom bits are read as one
go and later mapped to calibration data for MSM8939.

When a thermal zone is looked up by an ID and no zone is found matching
that ID, the thermal_zone_get_by_id() function will return a pointer to
the thermal zone list head which isn't actually a valid thermal zone.
This can lead to a subsequent crash because a valid pointer is returned
to the called, but dereferencing that pointer as struct thermal_zone is
not safe.

The function rcar_gen3_thermal_calc_coefs() takes an argument called
'thcode' which shadows the static global 'thcode' variable. This is not
harmful but bad for readability and is harmful for planned changes to
the driver. The THCODE values should be read from hardware fuses if they
are available and only fallback to the global 'thcode' variable if they
are not fused.
Rename the global 'thcode' variable to 'thcodes' to avoid shadowing the
symbol in functions that take it as an argument.

The generic netlink is initialized at subsys_initcall, so far after
the thermal init routine and the thermal generic netlink family
initialization.
On ŝome platforms, that leads to a memory corruption.
The fix was sent to netdev@ to move the genetlink framework
initialization at core_initcall.
Move the thermal core initialization to postcore level which is very
close to core level.

The initcalls like to play joke. In our case, the thermal-netlink
initcall is called after the thermal-core initcall but this one sends
a notification before the former is initialized. No issue was spotted,
but it could lead to a memory corruption, so instead of relying on the
core_initcall for the thermal-netlink, let's initialize directly from
the thermal-core init routine, so we have full control of the init
ordering.

When the network is not configured, the netlink is disabled on all
the system. The thermal framework assumed the netlink is always
opt-in.
Fix this by adding a Kconfig option for the netlink notification,
defaulting to yes and depending on CONFIG_NET.
As the change implies multiple stubs and in order to not pollute the
internal thermal header, the thermal_nelink.h has been added and
included in the thermal_core.h, so this one regain some kind of
clarity.

This reverts commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6
The above patch is supposed to fix a register index error on mt2701. It
is not clear if the problem solved is a hang or just an invalid value
returned, my guess is the second. The patch introduces, though, a new
hang on MT8173 device making them unusable. So, seems reasonable, revert
the patch because introduces a worst issue.
The reason I send a revert instead of trying to fix the issue for MT8173
is because the information needed to fix the issue is in the datasheet
and is not public. So I am not really able to fix it.
Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173
devices.
