Subject[Patch net-next v12 05/13] net: dsa: microchip: add DSA support for microchip LAN937x
Date
Basic DSA driver support for lan937x and the device will be
configured through SPI interface.

drivers/net/dsa/microchip/ path is already part of MAINTAINERS &
the new files come under this path. Hence no update needed to the
MAINTAINERS

Reused KSZ APIs for port_bridge_join() & port_bridge_leave() and
added support for port_stp_state_set().

RGMII internal delay values for the mac is retrieved from
rx-internal-delay-ps & tx-internal-delay-ps as per the feedback from
v3 patch series.
https://lore.kernel.org/netdev/20210802121550.gqgbipqdvp5x76ii@skbuf/

It supports standard delay 2ns only. If the property is not found, the
value will be forced to 0.
