The Berlin SoC has a two SATA ports. Add a PHY driver to handle them. The mode selection can let us think this PHY can be configured to fit other purposes. But there are reasons to think the SATA mode will be the only one usable: the PHY registers are only accessible indirectly through two registers in the SATA range, the PHY seems to be integrated and no information tells us the contrary. For these reasons, make the driver a SATA PHY driver.

of_match_table is NULL for Non-DT based. Better to use the of_match_ptr(). If driver is DT based 'of_match_table = phy_berlin_sata_of_match' else 'of_match_table = NULL' This is take care by of_match_ptr() macro. Thanks, Varka Bhadram
