Merge branch 'ravb-r8a7795' 

Simon Horman says:

====================
ravb: Add support for r8a7795 SoC

please consider this series for net-next.
It enhances the ravb driver to support the r8a7795 SoC.

Changes:

* Dropped RFC prefix
* Details in changelog of individual patches

Base:

* net-next/master

Availability:

To aid review of this in conjunction with other EtherAVB changes
the following branches are available in my renesas tree on kernel.org.

* me/r8a7795-ravb-driver-v4: this series
* me/r8a7795-ravb-pfc-v2: r8a7795 sh-pfc update for EthernetAVB
* me/r8a7795-ravb-integration-v4: enable EthernetAVB on r8a7795
* me/r8a7795-ravb-driver-and-integration-v4.runtime:
      the above three branches with their runtime dependencies
