However, some switches have internal PHYs but NOT starting from port 0. For example 88e6393X, 88E6193X and 88E6191X have integrated PHYs available on ports 1 to 8 To properly support this offset, add a new field to allow specifying an internal PHYs layout. If field is not set, default layout is assumed (start at port 0) Reviewed-by: Andrew Lunn --- Changes since v2: - move start/end computation out of for loop - remove whitespace Signed-off-by: Alexis Lothoré --- drivers/net/dsa/mv88e6xxx/chip.c | 4 +++- drivers/net/dsa/mv88e6xxx/chip.h | 5 +++++ drivers/net/dsa/mv88e6xxx/global2.c | 5 ++++- 3 files changed, 12 insertions(+), 2 deletions(-) diff --git a/drivers/net/dsa/mv88e6xxx/chip.c b/drivers/net/dsa/mv88e6xxx/chip.c index c812e52bb5b7..2716d17c5c49 100644 --- a/drivers/net/dsa/mv88e6xxx/chip.c +++ b/drivers/net/dsa/mv88e6xxx/chip.c @@ -465,7 +465,9 @@ static int mv88e6xxx_port_setup_mac(struct mv88e6xxx_chip *chip, int port, static int mv88e6xxx_phy_is_internal(struct mv88e6xxx_chip *chip, int port) { - return port < chip->info->num_internal_phys; + return port >= chip->info->internal_phys_offset && + port < chip->info->num_internal_phys + + chip->info->internal_phys_offset; } static int mv88e6xxx_port_ppu_updates(struct mv88e6xxx_chip *chip, int port) diff --git a/drivers/net/dsa/mv88e6xxx/chip.h b/drivers/net/dsa/mv88e6xxx/chip.h index da6e1339f809..eca51946c100 100644 --- a/drivers/net/dsa/mv88e6xxx/chip.h +++ b/drivers/net/dsa/mv88e6xxx/chip.h @@ -167,6 +167,11 @@ struct mv88e6xxx_info { /* Supports PTP */ bool ptp_support; + + /* Internal PHY start index. 0 means that internal PHYs range starts at + * port 0, 1 means internal PHYs range starts at port 1, etc + */ + unsigned int internal_phys_offset; }; struct mv88e6xxx_atu_entry { diff --git a/drivers/net/dsa/mv88e6xxx/global2.c b/drivers/net/dsa/mv88e6xxx/global2.c index 615896893076..937a01f2ba75 100644 --- a/drivers/net/dsa/mv88e6xxx/global2.c +++ b/drivers/net/dsa/mv88e6xxx/global2.c @@ -1196,9 +1196,12 @@ int mv88e6xxx_g2_irq_setup(struct mv88e6xxx_chip *chip) int mv88e6xxx_g2_irq_mdio_setup(struct mv88e6xxx_chip *chip, struct mii_bus *bus) { + int phy_start = chip->info->internal_phys_offset; + int phy_end = chip->info->internal_phys_offset + + chip->info->num_internal_phys; int phy, irq; - for (phy = 0; phy < chip->info->num_internal_phys; phy++) { + for (phy = phy_start; phy < phy_end; phy++) { irq = irq_find_mapping(chip->g2_irq.domain, phy); if (irq < 0) return irq;
