That will break the 6390! You need to add the new PHY for the 88E6341. Andrew

Avoiding forward declaration would mean to move about half of source code. mv88e6xxx_physid_for_family depends on mv88e6xxx_table which depends on all _ops structures which depends on all lot of other functions. I wanted to create a small fixup patch which can be easily backported to stable releases which are affected by this issue. If you do not like forward declarations, I can create a followup patch which moves this half of code in this file to avoid forward declaration. But having it in one patch would mean to complicate reviewing code... > > static int mv88e6xxx_mdio_read(struct mii_bus *bus, int phy, int reg) > > { > > struct mv88e6xxx_mdio_bus *mdio_bus = bus->priv; > > @@ -3040,24 +3042,9 @@ static int mv88e6xxx_mdio_read(struct mii_bus *bus, int phy, int reg) > > err = chip->info->ops->phy_read(chip, bus, phy, reg, &val); > > mv88e6xxx_reg_unlock(chip); > > > > - if (reg == MII_PHYSID2) { > > - /* Some internal PHYs don't have a model number. */ > > - if (chip->info->family != MV88E6XXX_FAMILY_6165) > > - /* Then there is the 6165 family.

That will break > the 6390! You need to add the new PHY for the 88E6341. I have not replaced anything. I just put there a new phy_id section for 88E6341. You are probably confused by 'git diff' output as quickly looking at it, somebody can think that there is phy replacement. But there is no replacement, I only added a new PHY. Entry for 88E6390 is still there! Also this is reason why I wanted to avoid big code movement. It will be harder to read the 'git diff' output in this patch.

First chip->info->family (enum mv88e6xxx_family; MV88E6XXX_FAMILY_6341) is mapped to enum mv88e6xxx_model (MV88E6341) via family_model_table[] and then enum mv88e6xxx_model (MV88E6341) is mapped to prod_num (MV88E6XXX_PORT_SWITCH_ID_PROD_6341) via mv88e6xxx_table[]. All this is done in mv88e6xxx_physid_for_family() function. So at the end, this function converts MV88E6XXX_FAMILY_6341 to MV88E6XXX_PORT_SWITCH_ID_PROD_6341. And therefore I do not see anything wrong in family_model_table[] table. I defined family_model_table[] table to just maps enum mv88e6xxx_family to enum mv88e6xxx_model as mv88e6xxx_table[] table already contains mapping from enum mv88e6xxx_model to phys_id, to simplify implementation.

I can change it in this way. I just thought that if prod_id is already defined for every model in mv88e6xxx_table[] table I could reuse it, instead of duplicating it... Anyway, now I'm looking at phy/marvell.c driver again and it supports only 88E6341 and 88E6390 families from whole 88E63xxx range. So do we need to define for now table for more than MV88E6XXX_FAMILY_6341 and MV88E6XXX_FAMILY_6390 entries? > + > static int mv88e6xxx_mdio_read(struct mii_bus *bus, int phy, int reg) > { > struct mv88e6xxx_mdio_bus *mdio_bus = bus->priv; > @@ -3056,7 +3068,7 @@ static int mv88e6xxx_mdio_read(struct mii_bus *bus, int phy, int reg) > * a PHY, > */ > if (!(val & 0x3f0)) > - val |= MV88E6XXX_PORT_SWITCH_ID_PROD_6390 >> 4; > + val |= family_model_table[chip->info->family] >> 4; > } > > and it compiles.

Probably not. I've no idea if the 6393 has an ID, so to be safe you should add that. Assuming it has a family of its own. Andrew

And i recently found out Marvell have some automotive switches, 88Q5xxx which are actually based around the same IP and could be added to this driver. They also might not have an ID. I suspect this list is going to get longer, so having it table driven will make that simpler, less error prone. Andrew

I now realize that I did not implement this for 6393, these PHYs are detected as mv88e6085 ... PHY [...] driver [Generic PHY] (irq=POLL) And it seems that this temperature sensor is different from 1510, 6341 and 6390 :) I will look into this and send a patch. Marek
