In VADC driver with recalibration parameter enabled and
MPP2 or MPP4 current sink configuration some ratiometric
channels report the adc code higher than maximum permitted
value.
VADC driver checks the adc code against the permitted
maximum value and overwrites adc code to permitted maximum
value if it is higher and this results into incorrect adc
readings.
Fix this problem by avoiding the adc code check when
recalibration parameter enabled.

In addition to bringing in upstream commits, this merge also makes minor
changes to mainitain compatibility with upstream:
The definition of list_next_entry in qcrypto.c and ipa_dp.c has been
removed, as upstream has moved the definition to list.h. The implementation
of list_next_entry was identical between the two.
irq.c, for both arm and arm64 architecture, has had its calls to
__irq_set_affinity_locked updated to reflect changes to the API upstream.
Finally, as we have removed the sleep_length member variable of the
tick_sched struct, all changes made by upstream commit ec804bd do not
apply to our tree and have been removed from this merge. Only
kernel/time/tick-sched.c is impacted.

commit 145e74a4e5022225adb84f4e5d4fff7938475c35 upstream.
Upper limit for write operations to temperature limit registers
was clamped to a fractional value. However, limit registers do
not support fractional values. As a result, upper limits of 127.5
degrees C or higher resulted in a rounded limit of 128 degrees C.
Since limit registers are signed, this was stored as -128 degrees C.
Clamp limits to (-55, +127) degrees C to solve the problem.
Value on writes to auto_temp[12]_min and auto_temp[12]_max were not
clamped at all, but masked. As a result, out-of-range writes resulted
in a more or less arbitrary limit. Clamp those attributes to (0, 127)
degrees C for more predictable results.

commit ead82d6792ef5c600d535bca6ec50a4da14ff7c7 upstream.
The mapping from OF device IDs to platform device IDs is wrong.
TYPE_NCPXXWB473 is 0, TYPE_NCPXXWL333 is 1, so
ntc_thermistor_id[TYPE_NCPXXWB473] is { "ncp15wb473", TYPE_NCPXXWB473 }
while
ntc_thermistor_id[TYPE_NCPXXWL333] is { "ncp18wb473", TYPE_NCPXXWB473 }.
So the name is wrong for all but the "ntc,ncp15wb473" entry, and the
type is wrong for the "ntc,ncp15wl333" entry.
So map the entries by index, it is neither elegant nor robust but at
least it is correct.

commit 59cf4243e557aa64ab2ef51280454aa1f3828e14 upstream.
In commit 9e8269de, support was added for ntc_thermistor devices being
declared in the device tree and implemented on top of IIO. With that
change, a dependency was added to the ntc_thermistor driver:
depends on (!OF && !IIO) || (OF && IIO)
This construct has the drawback that the driver can no longer be
selected when OF is set and IIO isn't, nor when IIO is set and OF is
not. This is a regression for the original users of the driver.
As the new code depends on IIO and is useless without OF, include it
only if both are enabled, and set the dependencies accordingly. This
is clearer, more simple and more correct.
