net: phylink, dsa: eliminate phylink_fixed_state_cb()

Move the callback into the phylink_config structure, rather than providing a callback to set this up. Signed-off-by: Russell King Tested-by: Florian Fainelli Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phylink: add separate pcs operations structure

2020-03-30T18:52:27+00:00

Add a separate set of PCS operations, which MAC drivers can use to couple phylink with their associated MAC PCS layer. The PCS operations include: - pcs_get_state() - reads the link up/down, resolved speed, duplex and pause from the PCS. - pcs_config() - configures the PCS for the specified mode, PHY interface type, and setting the advertisement. - pcs_an_restart() - restarts 802.3 in-band negotiation with the link partner - pcs_link_up() - informs the PCS that link has come up, and the parameters of the link. Link parameters are used to program the PCS for fixed speed and non-inband modes. Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phylink: rename 'ops' to 'mac_ops'

2020-03-30T18:52:27+00:00

Rename the bland 'ops' member of struct phylink to be a more descriptive 'mac_ops' - this is necessary as we're about to introduce another set of operations. Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller

Change phylink_mii_c22_pcs_set_advertisement() to take only the PHY interface and advertisement mask, rather than the full phylink state. Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phylink: propagate resolved link config via mac_link_up()

2020-02-27T20:02:14+00:00

Propagate the resolved link parameters via the mac_link_up() call for MACs that do not automatically track their PCS state. We propagate the link parameters via function arguments so that inappropriate members of struct phylink_link_state can't be accessed, and creating a new structure just for this adds needless complexity to the API.

net: phylink: add support for polling MAC PCS

2020-01-06T07:22:32+00:00

Some MAC PCS blocks are unable to provide interrupts when their status changes. As we already have support in phylink for polling status, use this to provide a hook for MACs to enable polling mode. The patch idea was picked up from Russell King's suggestion on the macb phylink patch thread here [0] but the implementation was changed. Instead of introducing a new phylink_start_poll() function, which would make the implementation cumbersome for common PHYLINK implementations for multiple types of devices, like DSA, just add a boolean property to the phylink_config structure, which is just as backwards-compatible. https://lkml.org/lkml/2019/12/16/603 Suggested-by: Russell King Signed-off-by: Vladimir Oltean Signed-off-by: David S.
