net: phy: mscc: use new PTP_MSGTYPE_* defines

2020-11-25T20:23:21+00:00

Use recently introduced PTP_MSGTYPE_SYNC and PTP_MSGTYPE_DELAY_REQ
defines instead of a driver internal enumeration.

net: phy: mscc: Add PTP support for 2 more VSC PHYs

2020-11-14T02:25:34+00:00

Add VSC8572 and VSC8574 in the PTP configuration
as they also support PTP.

net: phy: mscc: remove the use of .ack_interrupt()

2020-11-06T00:32:00+00:00

In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.

This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.

net: phy: mscc: implement generic .handle_interrupt() callback

2020-11-06T00:32:00+00:00

In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.

Also, remove the .did_interrupt() callback since it's not anymore used.

net: phy: mscc: use phy_trigger_machine() to notify link change

2020-11-06T00:31:59+00:00

According to the comment describing the phy_mac_interrupt() function, it
it intended to be used by MAC drivers which have noticed a link change
thus its use in the mscc PHY driver is improper and, most probably, was
added just because phy_trigger_machine() was not exported.
Now that we have acces to trigger the link state machine, use directly
the phy_trigger_machine() function to notify a link change detected by
the PHY driver.

net: phy: mscc: macsec: constify vsc8584_macsec_ops

2020-08-26T23:21:17+00:00

The only usage of vsc8584_macsec_ops is to assign its address to the
macsec_ops field in the phydev struct, which is a const pointer. Make it
const to allow the compiler to put it in read-only memory.
