Subject: [PATCH net-next v5 0/6] net: lan966x: Add lan966x switch driver

This patch series add support for Microchip lan966x driver

The lan966x switch is a multi-port Gigabit AVB/TSN Ethernet Switch with
two integrated 10/100/1000Base-T PHYs. In addition to the integrated PHYs,
it supports up to 2RGMII/RMII, up to 3BASE-X/SERDES/2.5GBASE-X and up to
2 Quad-SGMII/Quad-USGMII interfaces.

Initially it adds support only for the ports to behave as simple
NIC cards. In the future patches it would be extended with other
functionality like Switchdev, PTP, Frame DMA, VCAP, etc.

v4->v5:
- more fixes to the reset of the switch, require all resources before
  activating the hardware
- fix to lan966x-switch binding
- implement get/set_pauseparam in ethtool_ops
- stop calling lan966x_port_link_down when calling lan966x_port_pcs_set and
  call it in lan966x_phylink_mac_link_down

v3->v4:
- add timeouts when injecting/extracting frames, in case the HW breaks
- simplify the creation of the IFH
- fix the order of operations in lan966x_cleanup_ports
- fixes to phylink based on Russel review

v2->v3:
- fix compiling issues for x86
- fix resource management in first patch

v1->v2:
- add new patch for MAINTAINERS
- add functions lan966x_mac_cpu_learn/forget
- fix build issues with second patch
- fix the reset of the switch, return error if there is no reset controller
- start to use phylink_mii_c22_pcs_decode_state and
  phylink_mii_c22_pcs_encode_advertisement to remove duplicate code
