Also in:
lkml, netdev
Subsystem:
microchip ksz series ethernet switch driver, networking drivers, networking [dsa], open firmware and flattened device tree bindings, the rest · Maintainers:
Woojung Huh, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Andrew Lunn, Vladimir Oltean, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Revision v5 of 11 in this series.
Revisions (11)
Documentation in .yaml format and updates to the MAINTAINERS Also 'make dt_binding_check' is passed. Introduced rx-internal-delay-ps & tx-internal-delay-ps for RGMII internal delay along with min/max values. This is to address the Vladimir proposal from the previous revision and mdio details are added as suggested by Rob.
