Add functions to unregister phy fixup for modules.
int phy_unregister_fixup(const char *bus_id, u32 phy_uid, u32 phy_uid_mask)
Unregister phy fixup from phy_fixup_list per bus_id, phy_uid &
phy_uid_mask
int phy_unregister_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask)
Unregister phy fixup from phy_fixup_list.
Use it for fixup registered by phy_register_fixup_for_uid()
int phy_unregister_fixup_for_id(const char *bus_id)
Unregister phy fixup from phy_fixup_list.
Use it for fixup registered by phy_register_fixup_for_id()

Add new parameter mdix_ctrl to hold the user configuration.
Existing mdix maintain the current status of MDI(X) crossover performed or
not.
mdix_ctrl can configure either ETH_TP_MDI or ETH_TP_MDI_X orETH_TP_MDI_AUTO.

This patch adds an option to disable EEE advertisement in the generic PHY
by providing a mask of prohibited modes corresponding to the value found in
the MDIO_AN_EEE_ADV register.
On some platforms, PHY Low power idle seems to be causing issues, even
breaking the link some cases. The patch provides a convenient way for these
platforms to disable EEE advertisement and work around the issue.

Create an option CONFIG_LED_TRIGGER_PHY (default n), which will create a
set of led triggers for each instantiated PHY device. There is one LED
trigger per link-speed, per-phy.
The triggers are registered during phy_attach and unregistered during
phy_detach.
This allows for a user to configure their system to allow a set of LEDs
not controlled by the phy to represent link state changes on the phy.
LEDS controlled by the phy are unaffected.
For example, we have a board where some of the leds in the
RJ45 socket are controlled by the phy, but others are not. Using the
triggers provided by this patch the leds not controlled by the phy can
be configured to show the current speed of the ethernet connection. The
leds controlled by the phy are unaffected.

The PHY interrupts are now handled in a threaded interrupt handler,
which can sleep. The work queue is no longer needed, phy_change() can
be called directly. phy_mac_interrupt() still needs to be safe to call
in interrupt context, so keep the work queue, and use a helper to call
phy_change().

adds PHY-mode "trgmii" as an extension for the operation
mode of the PHY interface for PHY_INTERFACE_MODE_TRGMII.
and adds a variable trgmii inside mtk_mac as the indication
to make the difference between the MAC connected to internal
switch or connected to external PHY by the given configuration
on the board and then to perform the corresponding setup on
TRGMII hardware module.
