This driver provides access to the DPFE interface of Broadcom
STB SoCs. The firmware running on the DCPU inside the DDR PHY can
provide current information about the system's RAM, for instance
the DRAM refresh rate. This can be used as an indirect indicator
for the DRAM's temperature. Slower refresh rate means cooler RAM,
higher refresh rate means hotter RAM.
