Subject: [PATCH net-next v3 0/3] TSN endpoint Ethernet MAC driver

This series adds a driver for my FPGA based TSN endpoint Ethernet MAC.
It also includes the device tree binding.

The device is designed as Ethernet MAC for TSN networks. It will be used
in PLCs with real-time requirements up to isochronous communication with
protocols like OPC UA Pub/Sub.

v3:
 - set MAC mode based on PHY information (Andrew Lunn)
 - remove/postpone loopback mode interface (Andrew Lunn)
 - add suppress_preamble node support (Andrew Lunn)
 - add mdio timeout (Andrew Lunn)
 - no need to call phy_start_aneg (Andrew Lunn)
 - remove unreachable code (Andrew Lunn)
 - move 'struct napi_struct' closer to queues (Vinicius Costa Gomes)
 - remove unused variable (kernel test robot)
 - switch from mdio interrupt to polling
 - mdio register without PHY address flag
 - thread safe interrupt enable register
 - add PTP_1588_CLOCK_OPTIONAL dependency to Kconfig
 - introduce dmadev for DMA allocation
 - mdiobus for platforms without device tree
 - prepare MAC address support for platforms without device tree
 - add missing interrupt disable to probe error path

v2:
 - add C45 check (Andrew Lunn)
 - forward phy_connect_direct() return value (Andrew Lunn)
 - use phy_remove_link_mode() (Andrew Lunn)
 - do not touch PHY directly, use PHY subsystem (Andrew Lunn)
 - remove management data lock (Andrew Lunn)
 - use phy_loopback (Andrew Lunn)
 - remove GMII2RGMII handling, use xgmiitorgmii (Andrew Lunn)
 - remove char device for direct TX/RX queue access (Andrew Lunn)
 - mdio node for mdiobus (Rob Herring)
 - simplify compatible node (Rob Herring)
 - limit number of items of reg and interrupts nodes (Rob Herring)
 - restrict phy-connection-type node (Rob Herring)
 - reference to mdio.yaml under mdio node (Rob Herring)
 - remove device tree (Michal Simek)
 - fix %llx warning (kernel test robot)
 - fix unused tmp variable warning (kernel test robot)
 - add missing of_node_put() for of_parse_phandle()
 - use devm_mdiobus_alloc()
 - simplify mdiobus read/write
 - reduce required nodes
 - ethtool priv flags interface for loopback
 - add missing static for some functions
 - remove obsolete hardware defines

Gerhard Engleder (3):
  dt-bindings: Add vendor prefix for Engleder
  dt-bindings: net: Add tsnep Ethernet controller
  tsnep: Add TSN endpoint Ethernet MAC driver
