From: Markus Mayer <mmayer at broadcom.com>

This series introduces a driver to interact with the Broadcom STB DDR
PHY Front End (DPFE), specifically to communicate with the DCPU that is
part of the DDR PHY and which is running its own firmware.

The DCPU provides information such as DRAM refresh rate, which can be
used as indirect indicator for the DRAM temperature (the higher the
refresh rate, the hotter the RAM).
