Commit Message

Christian Marangi Nov. 20, 2023, 1:50 p.m. UTC 
Add support for defining shared data size for PHY package defined in DT.

A PHY driver has to define the value .phy_package_priv_data_size to make
the generic OF PHY package function alloc priv data in the shared struct
for the PHY package.
