This patch serie adds support for Microchip lan966x serdes. The lan966x
device which contains this serdes has 8 interfaces, consisting of 2
copper transceivers, 3 Serdes and 2 RGMII interfaces and 2 of the
Serdes support QSGMII. The driver add the functionality of "muxing" the
interfaces to different switch ports.
The following table shows which interfaces can be supported by the port.
PortNumber Max Speed Ethernet interface options
0 1Gbps CuPHY, 1G SGMII or QSGMII
1 1Gbps CuPHY, 1G SGMII or QSGMII
2 2.5Gbps 2.5G SGMII, QSGMII, RGMII
3 2.5Gbps 2.5G SGMII, QSGMII, RGMII
4 2.5Gbps 2.5G SGMII, QSGMII
5 1Gbps QSGMII, RGMII
6 1Gbps QSGMII, RGMII
7 1Gbps QSGMII
v2->v3:
- remove unused includes
- add missing '...' in microchip,lan966x-serdes.yaml
- rename lan966x-serdes.h to phy-lan966x-serdes.h
- Rename CU->PHY and RG->RGMII
- update commit message for PATCH 2
v1->v2:
- replace the regmap with iomem
- update DT bindings
Horatiu Vultur (3):
dt-bindings: phy: Add lan966x-serdes binding
dt-bindings: phy: Add constants for lan966x serdes
phy: Add lan966x ethernet serdes PHY driver
