net: phy: Do not perform software reset for Generic PHY

2017-03-06T01:57:27+00:00

The Generic PHY driver is a catch-all PHY driver and it should preserve
whatever prior initialization has been done by boot loader or firmware
agents. For specific PHY device configuration it is expected that a
specialized PHY driver would take over that role.

Resetting the generic PHY was a bad idea that has lead to several
complaints and downstream workarounds e.g: in OpenWrt/LEDE so restore
the behavior prior to 87aa9f9c61ad ("net: phy: consolidate PHY
reset in phy_init_hw()").

net: phy: Check phydev->drv

2017-02-20T15:15:11+00:00

There are number of function calls, originating from user-space,
typically through the Ethernet driver that can make us crash by
dereferencing phydev->drv which will be NULL once we unbind the driver
from the PHY.

There are still functional issues that prevent an unbind then rebind to
work, but these will be addressed separately.

net: phy: Allow pre-declaration of MDIO devices

2017-02-07T15:51:46+00:00

Allow board support code to collect pre-declarations for MDIO devices by
registering them with mdiobus_register_board_info(). SPI and I2C buses
have a similar feature, we were missing this for MDIO devices, but this
is particularly useful for e.g: MDIO-connected switches which need to
provide their port layout (often board-specific) to a MDIO Ethernet
switch driver.

net: phy: Add 2000base-x, 2500base-x and rxaui modes

2017-02-07T15:34:42+00:00

The mv88e6390 ports 9 and 10 supports some additional PHY modes. Add
these modes to the PHY core so they can be used in the binding.

phy: increase size of MII_BUS_ID_SIZE and bus_id

2017-01-19T16:46:20+00:00

Some bus names are pretty long and do not fit into
17 chars. Increase therefore MII_BUS_ID_SIZE and
phy_fixup.bus_id to larger number. Now mii_bus.id
can host larger name.

phy: add phy fixup unregister functions

2016-12-08T19:21:47+00:00

>From : Woojung Huh 

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.

net: phy: add an option to disable EEE advertisement

2016-11-30T00:38:31+00:00

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.
