16466f4284 net: phy: bcm7xxx: remove 28nm wildcard entry
A wildcard entry with the 32-bits OUI 0x600d8400 was added as part of
the BCM7xxx internal PHY driver, but that entry might match other PHYs
that are not covered by this driver, so let's just remove it.

a62ea5a75f net: phy: bcm7xxx: properly clear AFE_RX_LP_COUNTER
The AFE_RX_LP_COUNTER kept the last 3 bits set, which would not properly
clear the EEE LPI mode errors bits. Make sure that those bits are set to
0 to ensure the PHY timing is always good even during EEE wake-up.

9918542e2d net: phy: bcm7xxx: fix spurious MDIO failures during workaround
Writing first to the AFE registers, and then the VCO, RCAL, RC_CAL
registers turned out to unveil some spurious MDIO read/write failures
which would make the workaround partially applied. The fix is to write
first to the VCO, RCAL, RC_CAL registers, and then write to the AFE
registers.

a3622f2c82 net: phy: bcm7xxx: define constants for our registers
Define constants for the various registers used in
bcm7xxx_28nm_afe_config_init() to help clarify what this workaround is
about.

b560a58c45 net: phy: add Broadcom BCM7xxx internal PHY driver
This patch adds support for the Broadcom BCM7xxx Set Top Box SoCs
internal PHYs. This driver supports the following generation of SoCs:

- BCM7366, BCM7439, BCM7445 (28nm process)
- all 40nm and 65nm (older MIPS-based SoCs)

The PHYs on these SoCs require a bunch of workarounds to operate
correctly, both during configuration time and at suspend/resume time,
the driver handles that for us.
