This patch is against the 'renesas-devel-20170213-v4.10-rc8' tag of Simon
Horman's 'renesas.git' repo.

   The binding was documented in the IMR driver patch. I don't expect it to
change even if the driver would be rewritten for DRM.

   The manual seems to suggest that IMR-LX4 devicec are different between 7795

    Devices, of course. :-)

and 7796 SoCs, so we may need SoC specific compatibility. I'll look into this...

    Found no difference between 7795/7796 (other than performance).
