This patch adds functionalities specific to mv88e6393x family (88E6393X, 88E6193X and 88E6191X). The main differences between previous devices and this one are: - port 0 can be a SERDES port - all SERDESes are one-lane, eg. no XAUI nor RXAUI - on the other hand the SERDESes can do USXGMII, 10GBASER and 5GBASER (on 6191X only one SERDES is capable of more than 1g; USXGMII is not yet supported with this change) - Port Policy CTL register is changed to Port Policy MGMT CTL register, via which serveral more registers can be accessed indirectly - egress monitor port is configured differently - ingress monitor/CPU/mirror ports are configured differently and can be configured per port (ie. each port can have different ingress monitor port, for example) - port speed AltBit works differently than previously - PHY registers can be also accessed via MDIO address 0x18 and 0x19 (on previous devices they could be accessed only via Global 2 offsets 0x18 and 0x19, which means two indirections; this feature is not yet leveraged with this patch) Co-developed-by: Ashkan Boldaji Signed-off-by: Ashkan Boldaji Signed-off-by: Pavana Sharma Co-developed-by: Marek Behún Signed-off-by: Marek Behún --- drivers/net/dsa/mv88e6xxx/chip.c | 150 +++++++++++++ drivers/net/dsa/mv88e6xxx/chip.h | 4 + drivers/net/dsa/mv88e6xxx/global1.h | 2 + drivers/net/dsa/mv88e6xxx/global2.h | 8 + drivers/net/dsa/mv88e6xxx/port.c | 268 +++++++++++++++++++++++ drivers/net/dsa/mv88e6xxx/port.h | 47 ++++- drivers/net/dsa/mv88e6xxx/serdes.c | 316 ++++++++++++++++++++++++++++ drivers/net/dsa/mv88e6xxx/serdes.h | 44 ++++ 8 files changed, 837 insertions(+), 2 deletions(-) diff --git a/drivers/net/dsa/mv88e6xxx/chip.c b/drivers/net/dsa/mv88e6xxx/chip.c index 62bef0759077..586aeef56a98 100644 --- a/drivers/net/dsa/mv88e6xxx/chip.c +++ b/drivers/net/dsa/mv88e6xxx/chip.c @@ -635,6 +635,29 @@ static void mv88e6390x_phylink_validate(struct mv88e6xxx_chip *chip, int port, mv88e6390_phylink_validate(chip, port, mask, state);

The original 16-bit value is divided into first two 8-bit register in the Port Policy MGMT CTL. We can therefore use the previous code to compute the mask and shift, and then - if 0 <= shift < 8, we access register 0 in Port Policy MGMT CTL - if 8 <= shift < 16, we access register 1 in Port Policy MGMT CTL There are in fact other possible policy settings for Amethyst which could be added here, but this can be done in the future.
