This series adds support for creating PCSs as devices on a bus with a driver (patch 3). As initial users,
- The Lynx PCS (and all of its users) is converted to this system (patch 5) - The Xilinx PCS is broken out from the AXI Ethernet driver (patches 6-8) - The Cadence MACB driver is converted to support external PCSs (namely the Xilinx PCS) (patches 9-10). The last few patches add device links for pcs-handle to improve boot times, and add compatibles for all Lynx PCSs. Care has been taken to ensure backwards-compatibility. The main source of this is that many PCS devices lack compatibles and get detected as PHYs. To address this, pcs_get_by_fwnode_compat allows drivers to edit the devicetree to add appropriate compatibles. This is technically a v3 (with [1,2] being v1 and v2, respectively), but there have been so many architectural changes that I didn't bother maintaining the series changelog. I think it is best to review this series independently of its past iterations. I submitted this as an RFC since net-next is closed, but I believe this series is fully tested and ready to be applied.
