If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/thermal/tango_thermal.ko | grep alias

When this platform is suspended, firmware powers the entire SoC down,
except a few hardware blocks waiting for wakeup events. There is no
context to save for this particular block.Therefore, there is nothing useful for the driver to do on suspend;
so we define a NULL suspend hook. On resume, the driver initializes
the block exactly as is done in the probe callback.Signed-off-by: Marc Gonzalez

The Tango thermal driver provides support for the primitive temperature
sensor embedded in Tango chips since the SMP8758.This sensor only generates a 1-bit signal to indicate whether the die
temperature exceeds a programmable threshold.Signed-off-by: Marc Gonzalez
