Florian Fainelli fe26821fa6 net: phy: broadcom: Wire suspend/resume for BCM54810
The BCM54810 PHY can use the standard BMCR Power down suspend, but needs
a custom resume routine which first clear the Power down bit, and then
re-initializes the PHY. While in low-power mode, the PHY only accepts
writes to the BMCR register. The datasheet clearly says it:

Reads or writes to any MII register other than MII Control register
(address 00h) while the device is in the standby power-down mode may
cause unpredictable results.

Florian Fainelli cb64da3a5b net: phy: broadcom: Have bcm54xx_adjust_rxrefclk() check for flags
bcm54xx_adjust_rxrefclk() already checks for PHY_BRCM_AUTO_PWRDWN_ENABLE
and PHY_BRCM_DIS_TXCRXC_NOENRGY in order to set the appropriate bit. The
situation is a bit more complicated with the flag
PHY_BRCM_RX_REFCLK_UNUSED but essentially amounts to the same situation.

The default setting for the 125MHz clock is to be on for all PHYs and
we still treat BCM50610 and BCM50610M specifically with the polarity of
the bit reversed.

Tao Ren b9bcb95315 net: phy: broadcom: add 1000Base-X support for BCM54616S
The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly
because genphy functions are designed for copper links, and 1000Base-X
(clause 37) auto negotiation needs to be handled differently.

This patch enables 1000Base-X support for BCM54616S by customizing 3
driver callbacks, and it's verified to be working on Facebook CMM BMC
platform (RGMII->1000Base-KX):

  - probe: probe callback detects PHY's operation mode based on
    INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX
    Control register.

  - config_aneg: calls genphy_c37_config_aneg when the PHY is running in
    1000Base-X mode; otherwise, genphy_config_aneg will be called.

  - read_status: calls genphy_c37_read_status when the PHY is running in
    1000Base-X mode; otherwise, genphy_read_status will be called.

Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and
100Base-FX support is not available as of now.

Heiner Kallweit dcdecdcfe1 net: phy: switch drivers to use dynamic feature detection
Recently genphy_read_abilities() has been added that dynamically detects
clause 22 PHY abilities. I *think* this detection should work with all
supported PHY's, at least for the ones with basic features sets, i.e.
PHY_BASIC_FEATURES and PHY_GBIT_FEATURES. So let's remove setting these
features explicitly and rely on phylib feature detection.

I don't have access to most of these PHY's, therefore I'd appreciate
regression testing.

v2:
- make the feature constant a comment so that readers know which
  features are supported by the respective PHY

This extra BCM54612E code in PHY driver isn't really aneg specific. Even
without it aneg works OK but the problem is no packets pass through PHY.

Moreover putting this code inside config_aneg callback didn't allow
resuming PHY correctly. When driver called phy_stop and phy_start it was
putting PHY machine into RESUMING state. After that machine was
switching into AN and NOLINK without ever calling phy_start_aneg. This
prevented this extra setup from being called and PHY didn't work.

Timur Tabi 529ed12752 net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause
Instead of having individual PHY drivers set the SUPPORTED_Pause and
SUPPORTED_Asym_Pause flags, phylib itself should set those flags,
unless there is a hardware erratum or other special case.  During
autonegotiation, the PHYs will determine whether to enable pause
frame support.

Pause frames are a feature that is supported by the MAC.  It is the MAC
that generates the frames and that processes them.  The PHY can only be
configured to allow them to pass through.

This commit also effectively reverts the recently applied c7a61319
("net: phy: dp83848: Support ethernet pause frames").

So the new process is:

1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause
and SUPPORTED_AsymPause bits in phydev->supported.  This indicates that
the PHY supports pause frames.

2) The MAC driver checks phydev->supported before it calls phy_start().
If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver
sets those bits in phydev->advertising, if it wants to enable pause
frame support.

3) When the link state changes, the MAC driver checks phydev->pause and
phydev->asym_pause,  If the bits are set, then it enables the corresponding
features in the MAC.  The algorithm is:

	if (phydev->pause)
		The MAC should be programmed to receive and honor
                pause frames it receives, i.e. enable receive flow control.

	if (phydev->pause != phydev->asym_pause)
		The MAC should be programmed to transmit pause
		frames when needed, i.e. enable transmit flow control.

Commit 439d39a9ac ("net: phy: broadcom:
extract register definitions") added a bunch of registers to brcmphy.h
but left some to broadcom.c, move all of them to the header file since
the BCM54xx and BCM7xxx PHY drivers do share all of these registers.

Florian Fainelli 439d39a9ac net: phy: broadcom: extract register definitions
The Broadcom BCM54xx register definitions are shared between BCM54xx and
BCM7xx internal PHYs for which we are adding support. Extract these
register definitions and put them in include/linux/brcmphy.h for use by
the BCM7xxx internal PHY driver.

Christian Hohnstaedt d5bf9071e7 phylib: Support registering a bunch of drivers
If registering of one of them fails, all already registered drivers
of this module will be unregistered.

Use the new register/unregister functions in all drivers
registering more than one driver.

amd.c, realtek.c: Simplify: directly return registration result.

Tested with broadcom.c
All others compile-tested.

Uwe Kleine-König cf93c94581 net/phy: fix many "defined but unused" warnings
MODULE_DEVICE_TABLE only expands to something if it's compiled
for a module.  So when building-in support for the phys, the
mdio_device_id tables are unused.  Marking them with __maybe_unused
fixes the following warnings:
