Subject: [PATCH net-next v2 0/9] Add PCS support for Renesas RZ/{T2H,N2H} SoCs

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This series aims to add PCS support for the Renesas RZ/T2H and RZ/N2H SoCs
These SoCs include a MII converter (MIIC) that converts MII to RMII/RGMII
or can be set in pass-through mode for MII similar to the RZ/N1 SoC. The
MIIC is used in conjunction with the Ethernet switch (ETHSW) available on
these SoCs.

v1->v2:
- Dropped regx in title and description in patch 1/9.
- As done for other IPs used T2H compatible as a fallback for N2H.
- Renamed pcs-rzt2h-miic.h -> renesas,r9a09g077-pcs-miic.h
- Added matrix table in the new header file.
- Corrected the resets check for RZ/N1.
- Updated the commit message in patch 1/9.
- Dropped regx in config description in patch 9/9.
- Dropped patch "net: pcs: rzn1-miic: Add PCS validate callback
  for RZ/T2H MIIC" is this already taken care in commit 508df2de7b3e
  as pointed by Russell King.

Cheers,
Prabhakar
