The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics and
a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp
was renamed to strncasecmp, and strnicmp made into a wrapper for the new
strncasecmp to avoid breaking existing users.
To allow the compat wrapper strnicmp to be removed at some point in the
future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

DT-enabled Dove has moved from ARCH_DOVE in mach-dove to MACH_DOVE
in mach-mvebu. As non-DT ARCH_DOVE will stay to rot for a while, add a new
DT-only MACH_DOVE to thermal Kconfig.
This was originally supposed to go in via "ARM: dove: prepare new Dove DT Kconfig"
patch from Sebastian Hesselbarth for 3.15, but slipped through the cracks.
I've tested on CuBox that without this patch you can't compile
dove_thermal into a mach-mvebu based kernel, and with this patch I can
build the driver and it works as expected run-time.

On latest i.MX6 SOC with thermal calibration data of 0x5A100000,
the critical trip temperature will be an invalid value and
cause system auto shutdown as below log:
thermal thermal_zone0: critical temperature reached(42 C),shutting down
So, with universal formula for thermal sensor, only room
temperature point is calibrated, which means the calibration
data read from fuse only has valid data of bit [31:20], others
are all 0, the critical trip point temperature can NOT depend
on the hot point calibration data, here we set it to 20 C higher
than default passive temperature.

When binding cooling devices to thermal zones created from the device
tree the minimum and maximum cooling states are in the wrong order
leading to failure to bind.
Fix the order of cooling states in the call to
thermal_zone_bind_cooling_device to fix this.

While dealing with this problem, I found another problem that also
results in a kernel crash on thermal module removal:

Subject: [PATCH] thermal: hwmon: Make the check for critical temp valid consistent
We used the tz->ops->get_crit_temp && !tz->ops->get_crit_temp(tz, temp)
to decide if we need to create the temp_crit attribute file but we just
check if tz->ops->get_crit_temp exists to decide if we need to remove
that attribute file. Some ACPI thermal zone doesn't have a valid critical
trip point and that would result in removing a non-existent device file
on thermal module unload.
