[PATCH 0/2] Thermal MMIO Driver

[Talel Shenhar <talel@amazon.com>]

This series introduces the generic thermal MMIO driver that will use
memory mapped reads to get the temperature.  Any HW/System that
allows temperature reading by a single memory-mapped reading, be it
register or shared memory, is a potential candidate to work with this
driver.

This driver is most suitable for cases such as the following:
- The entire thermal HW setup is done by another SW entity (e.g.
  bootloader) and all that is left is to read the current temperature from
  a register.
- The thermal HW setup is done via an external CPU (e.g. micro-controller)
  and that CPU has is using shared memory that can be memory-mapped to this
  driver.
- The thermal HW setup and reading is done via CPLD, which exports the
  current temperature to the system via a register.
- The thermal HW is working out-of-the-box and only reports temperature via
  a single register access.
