Subject: [PATCH 00/10] Add Gigabit Ethernet driver support

The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.

The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE)  and Dedicated Direct memory access controller
(DMAC).

With a few changes in the driver we can support both IPs.

This patch series is in preparation for adding Gigabit ethernet driver support to RZ/G2L SoC.

The number of patches after incorporatng RFC review comments is 19.
So splitting the patches into 2 patchsets (10 + 9).

The series is the first patchset which aims to add RZ/G2L SoC with
compatible strings, E-MAC and D-MAC initialization.

Second patchset basically fillup all the stubs for the full Gigabit
Ethernet functionality.

RFC->V1:
 * Added Rb tags of patch#1 and patch #9
 * Renamed "rgeth" to gbeth
 * Renamed the variable "no_ptp_cfg_active" with "gptp" and
   "ptp_cfg_active" with "ccc_gac
 * Handled NC queue only for R-Car.
 * Removed RIC3 initialization from DMAC init, as it is 
   same as reset value.
 * moved stubs function to patch#4.
 * Added tsrq variable instead of multi_tsrq feature bit.
 * moved CSR0 initialization from E-MAC init to later patch.
 * started using ravb_modify for initializing link registers.
