[PATCH 5/5] net: phy: marvell10g: Adapt Marvell 10G PHY driver from Linux

Sun Mar 19 18:08:10 CET 2023
Pull Marvell 10G PHY driver from Linux 6.1.y as of commit
d6d29292640d3 ("net: phy: marvell10g: select host interface configuration")
and heavily adapt to match U-Boot PHY framework. Support for
hwmon is removed as is much other functionality which could
not be tested, this results in much simpler driver which can
only bring the PHY up and set MAC type.

+ * Marvell 10G 88x3310 PHY driver
+ *
+ * Based upon the ID registers, this PHY appears to be a mixture of IPs
+ * from two different companies.
+ *
+ * There appears to be several different data paths through the PHY which
+ * are automatically managed by the PHY. The following has been determined
+ * via observation and experimentation for a setup using single-lane Serdes:
+ *
+ * SGMII PHYXS -- BASE-T PCS -- 10G PMA -- AN -- Copper (for <= 1G)
+ * 10GBASE-KR PHYXS -- BASE-T PCS -- 10G PMA -- AN -- Copper (for 10G)
+ * 10GBASE-KR PHYXS -- BASE-R PCS -- Fiber
+ *
+ * With XAUI, observation shows:
+ *
+ * XAUI PHYXS -- <appropriate PCS as above>
+ *
+ * and no switching of the host interface mode occurs.
+ *
+ * If both the fiber and copper ports are connected, the first to gain
+ * link takes priority and the other port is completely locked out.
