Subject[PATCH v4 0/3] phy: Add driver for lan966x Serdes driver
Date
This patch serie adds support for Microchip lan966x serdes. The lan966x
device contains has 7 interfaces, consisting of 2 copper transceivers,
3 Serdes and 2 RGMII interfaces. Two of the Serdes support QSGMII.
The driver also adds the functionality of "muxing" the interfaces to
different logical 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

v3->v4:
- update description of the driver
- removed unused registers
- use bitfield operations in the registers
- add macros for PLL configuration
- move macros and structs at the top of the file

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

dt-bindings: phy: Add constants for lan966x serdes
phy: Add lan966x ethernet serdes PHY driver
