+description:
+ PHY packages are multi-port Ethernet PHY of the same family
+ and each Ethernet PHY is affected by the global configuration
+ of the PHY package.
+
+ Each reg of the PHYs defined in the PHY package node is
+ absolute and describe the real address of the Ethernet PHY on
+ the MDIO bus.

+ description:
+ The base ID number for the PHY package.
+ Commonly the ID of the first PHY in the PHY package.
+
+ Some PHY in the PHY package might be not defined but
+ still occupy ID on the device (just not attached to
+ anything) hence the PHY package reg might correspond
+ to a not attached PHY (offset 0).

Document ethernet PHY package nodes used to describe PHY shipped in bundle of 2-5 PHY. The special node describe a container of PHY that share common properties. This is a generic schema and PHY package should create specialized version with the required additional shared properties. Example are PHY packages that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node MUST declare the base address used by the PHY driver for global configuration by calculating the offsets of the global PHY based on the base address of the PHY package. Each reg of the PHYs defined in the PHY package node is absolute and describe the real address of the Ethernet PHY on the bus.
