[PATCH net-next 00/11] phylib consolidation

[PATCH net-next 00/11] phylib consolidation

[Russell King - ARM Linux admin]

Hi,

Over the last few releases, there has been a push to clean up and
consolidate the phylib code. Some cases have been missed, and this
series catches those cases.

1. Remove redundant .aneg_done initialisers; calling genphy_aneg_done()
   for clause 22 PHYs is the default when .aneg_done is not set.

2. Some PHY drivers manually set phydev->pause and phydev->asym_pause,
   but we have a helper for this - phy_resolve_aneg_pause(), introduced
   in 2d880b8709c0 ("net: phy: extract pause mode").  Use this in the
   lxt, marvell and uPD60620 drivers.

   Incidentally, this brings up the question whether marvell fiber mode
   is correctly interpreting and advertising the pause parameters.

3. Add a genphy_check_and_restart_aneg() helper, which complements the
   clause 45 version of this. This will be useful for PHY drivers that
   open code this logic (e.g. marvell.c)

4. Add a genphy_read_status_fixed() helper to read the fixed-mode
   status from a clause 22 PHY.  lxt and marvell both contain copies
   of this code, so convert them over.

5. Arrange marvell driver to use genphy_read_lpa() for copper mode.
   This needs some rearrangement of the code in
   marvell_read_status_page_an(), but preserves using the PHY specific
   status register to derive the current negotiation results.

6. Simplify the marvell driver so we can use the
   genphy_read_status_fixed() helper directly rather than
   marvell_read_status_page_fixed().

7. Use positive logic in the marvell driver to determine the link
   state, and get rid of the REGISTER_LINK_STATUS definition; we
   already have a definition for this.

8. The marvell driver reads the PHY specific status register multiple
   times when determining the status: once in marvell_update_link()
   and again in marvell_read_status_page_an(). This is a waste;
   rearrange to read the status register once, and pass its value into
   marvell_read_status_page_an().  We preserve using
   genphy_update_link() for the copper side.

9. The marvell driver was using private clause 37 definitions, but we
   have clause 37 definitions in uapi/linux/mii.h. Use the generic
   definitions.

10. Switch the marvell driver to use phy_modify_changed() to modify
    the fiber advertisement.

11. Switch the marvell driver to use genphy_check_and_restart_aneg()
    introduced above rather than open-coding this functionality.

[PATCH net-next 01/11] net: phy: remove redundant .aneg_done initialisers

[Russell King]

Remove initialisers that set .aneg_done to genphy_aneg_done - this is
the default for clause 22 PHYs, so the initialiser is redundant.

[PATCH net-next 02/11] net: phy: use phy_resolve_aneg_pause()

[Russell King]

Several drivers code their own version of this, working from the LPA
register, after setting the ethtool link partner advertisement bitmask.
Use the generic function instead.

[PATCH net-next 04/11] net: phy: provide and use genphy_read_status_fixed()

[Russell King]

There are two drivers and generic code which contain exactly the same
code to read the status of a PHY operating without autonegotiation
enabled. Rather than duplicate this code, provide a helper to read
this information.

[PATCH net-next 06/11] net: phy: marvell: initialise link partner state earlier

[Russell King]

Move the initialisation of the link partner state earlier, inside
marvell_read_status_page(), so we don't have the same initialisation
scattered amongst the other files.  This is in a similar place to
the genphy implementation, so would result in the same behaviour if
a PHY read error occurs.

This allows us to get rid of marvell_read_status_page_fixed(), which
became a pointless wrapper around genphy_read_status_fixed().

[PATCH net-next 07/11] net: phy: marvell: use positive logic for link state

[Russell King]

Rather than using negative logic:

	if (there is no link)
		set link = 0
	else
		set link = 1

use the more natural positive logic:

	if (there is link)
		set link = 1
	else
		set link = 0

[PATCH net-next 08/11] net: phy: marvell: consolidate phy status reading

[Russell King]

marvell_read_status_page_an() always reads the PHY status register, but
marvell_update_link() has already done this.  Rather than wastefully
reading the register twice in quick succession, read it once in
marvell_read_status_page() and use the result for both.

This makes marvell_update_link() rather pointless, so move it into
marvell_read_status_page().
