Subject: [PATCH net-next v2 0/2] ravb: Add MII support for R-Car V4M

	Hi all,

All EtherAVB instances on R-Car Gen3/Gen4 SoCs support the RGMII
interface.  In addition, the first two EtherAVB instances on R-Car V4M
also support the MII interface, but this is not yet supported by the
driver.  This patch series adds support for MII on R-Car Gen4, after the
customary cleanup.

Changes compared to v1[1]:
  - New patch "ravb: Improve ravb_hw_info instance order",
  - Add Reviewed-by,
  - Rename ravb_emac_init_rcar_apsr() to ravb_emac_init_rcar_gen4(),
  - Restrict MII support to R-Car Gen4 by adding a new ravb_hw_info
    instance.

The corresponding pin control support is available in [2].

Compile-tested only, as all AVB interfaces on the Gray Hawk Single
development board are connected to RGMII PHYs.
No regressions on R-Car V4H.

Thanks for your comments!
