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 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
v1 -> v2:
- replace the regmap with iomem
- update DT bindings

I'm guessing these are used for the phy cells? If so, I can't figure out
how and I shouldn't have to search the driver to figure it out.
What's CU? What's RG?

These are just some constatns to be able to select between the
integrated PHYs, RGMII, SerDes interfaces. Because these interfaces
needs to be muxed according to the HW.
This is something similar with the Ocelot Serdes where there are only
2 Serdes types.

Cu - copper PHY
RG - RGMII
I will create a new version where I will improve the log message.

These are just some constatns to be able to select between the
integrated PHYs, RGMII, SerDes interfaces. Because these interfaces
needs to be muxed according to the HW.
This is something similar with the Ocelot Serdes where there are only
2 Serdes types.

Cu - copper PHY
RG - RGMII
I will create a new version where I will improve the log message.
