Subject: [PATCH net-next v5 0/3] net: dsa: rzn1-a5psw: add support for vlan and .port_bridge_flags

From: Alexis Lothoré <alexis.lothore@...tlin.com>

Hello,
this series enables vlan support in Renesas RZN1 internal ethernet switch,
and is a follow up to the work initiated by Clement Leger a few months ago,
who handed me over the topic.
This new revision aims to iron the last few points raised by Vladimir to
ensure that the driver is in line with switch drivers expectations, and is
based on the lengthy discussion in [1] (thanks Vladimir for the valuable
explanations)

----
V5:
 - ensure that flooding can be enabled only if port belongs to a bridge
 - enable learning in a5psw_port_stp_state_set() only if port has learning
   enabled
 - toggle vlan tagging on vlan filtering in
 - removed reviewed-by on second patch since its modified

RESEND V4:
 - Resent due to net-next being closed

V4:
 - Fix missing CPU port bit in a5psw->bridged_ports
 - Use unsigned int for vlan_res_id parameters
 - Rename a5psw_get_vlan_res_entry() to a5psw_new_vlan_res_entry()
 - In a5psw_port_vlan_add(), return -ENOSPC when no VLAN entry is found
 - In a5psw_port_vlan_filtering(), compute "val" from "mask"

V3:
 - Target net-next tree and correct version...

V2:
 - Fixed a few formatting errors
 - Add .port_bridge_flags implementation

Clément Léger (3):
  net: dsa: rzn1-a5psw: use a5psw_reg_rmw() to modify flooding
    resolution
  net: dsa: rzn1-a5psw: add support for .port_bridge_flags
  net: dsa: rzn1-a5psw: add vlan support
