Hi all,

Here is a collection of little, independent improvements to the
brcmstb-avs-cpufreq driver.

- more flexible interface for __issue_avs_command()
  This change makes the function more versatile as it can handle input
  and output parameters at the same time.
- Support polling AVS firmware
  This change allows the driver to use polling if interrupt driven mode
  doesn't work for some reason.
- send S2_ENTER / S2_EXIT commands to AVS
  Let the AVS firmware know when we are about to enter, or have just
  exited, S2 mode.

Regards,
-Markus
