- address review comments on "net: dsa: microchip: enable EEE support"
  patch

changes v6:
- split patch set and send only first 9 patches
- Add Reviewed-by: Andrew Lunn <andrew@lunn.ch>
- use 0xffff instead of GENMASK
- Document @supported_eee
- use "()" with function name in comments

changes v5:
- spell fixes
- move part of genphy_c45_read_eee_abilities() to
  genphy_c45_read_eee_cap1()
- validate MDIO_PCS_EEE_ABLE register against 0xffff val.
- rename *eee_100_10000* to *eee_cap1*
- use linkmode_intersects(phydev->supported, PHY_EEE_CAP1_FEATURES)
  instead of !linkmode_empty()
- add documentation to linkmode/register helpers

changes v4:
- remove following helpers:
  mmd_eee_cap_to_ethtool_sup_t
  mmd_eee_adv_to_ethtool_adv_t
  ethtool_adv_to_mmd_eee_adv_t
  and port drivers from this helpers to linkmode helpers.
- rebase against latest net-next
- port phy_init_eee() to genphy_c45_eee_is_active()

changes v3:
- rework some parts of EEE infrastructure and move it to c45 code.
- add supported_eee storage and start using it in EEE code and by the
  micrel driver.
- add EEE support for ar8035 PHY
- add SmartEEE support to FEC i.MX series.

changes v2:
- use phydev->supported instead of reading MII_BMSR regiaster
- fix @get_eee > @set_eee

With this patch series we provide EEE control for KSZ9477 family of
switches and
AR8035 with i.MX6 configuration.
According to my tests, on a system with KSZ8563 switch and 100Mbit idle
link,
we consume 0,192W less power per port if EEE is enabled.
