[PATCH net-next 00/10] net: dsa: mv88e6xxx: Global (1) cosmetics

[Vivien Didelot]

The Global (1) internal SMI device of Marvell switches is a set of
registers providing support to different units for MAC addresses (ATU),
VLANs (VTU), PHY polling (PPU), etc.

Chips (like 88E6060) may use a different address for it, or have
subtleties in the units (e.g. different number of databases, changing
how registers must be accessed), making it hard to maintain properly.

This patchset is a first step to polish the Global (1) support, with no
functional changes though. Here's basically what it does:

  - add helpers to access Global1 registers (same for Global2)
  - remove a few family checks (VTU/STU FID registers)
  - s/mv88e6xxx_vtu_stu_entry/mv88e6xxx_vtu_entry/
  - add a per-chip mv88e6xxx_ops structure of function pointers:

  struct mv88e6xxx_ops {
        int (*get_eeprom)(struct mv88e6xxx_chip *chip,
                          struct ethtool_eeprom *eeprom, u8 *data);
        int (*set_eeprom)(struct mv88e6xxx_chip *chip,
                          struct ethtool_eeprom *eeprom, u8 *data);

        int (*set_switch_mac)(struct mv88e6xxx_chip *chip, u8 *addr);

        int (*phy_read)(struct mv88e6xxx_chip *chip, int addr, int reg,
                        u16 *val);
        int (*phy_write)(struct mv88e6xxx_chip *chip, int addr, int reg,
                         u16 val);
  };

Future patchsets will add ATU/VTU ops, software reset, etc.
