* realtek: do not reset SerDes on link changeBirger Koblitz2022-05-142-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not reset the RTL930x SerDes on link changes, instead set up the SDS with internal PHYs for the SFP+ ports only. This fixes the 8 1GBit ports on the Zyxel XGS1250 which do not work without this patch. A complete SerDes reset was performed on all SerDes links. For copper 1Gbit ports, this is commonly a single XGMII link to an RTL8218D. There is however no support for setting up the XGMII link on RTL9300/RTL9310, thereby wiping the (RX/TX) setup done by u-boot and breaking the 1GBit ports. No SerDes reset should be done for these links. The handling of SGMII/HiSGMII, 1000BX or 10GR links is actually entirely different. All these modes need to be suitably RX calibrated and the pre- main and post- amplifiers set up properly for TX. The 10GBit SFP+ fiber links are recalibrated instead of reset, which e.g. is necessary when someone pulls a module out and puts another in. This makes swapping out 10GBit fiber modules possible. 1GBit modules are not yet supported, nor any modules with an internal phy.

* realtek: Fix bug when accessing external PHYs on SoCs older than Revision CBirger Koblitz2021-10-091-3/+22
| | | | | | | | | | RTL8393 SoCs older than Revision C hang on accesses to PHYs with PHY address larger or equal to the CPU-port (52). This will make scanning the MDIO bus hang forever. Since the RTL8390 platform does not support more than 52 PHYs, return -EIO for phy addresses >= 52. Note that the RTL8390 family of SoCs has a fixed mapping between port number and PHY-address.
