net: phy: realtek: fix enabling of the TX-delay for RTL8211F

2016-11-28T17:06:54+00:00

The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
PHY driver to enable the RX and/or TX delays:
- PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
  PHY (if required, the MAC should add the delays in this case)
- PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
  (currently not supported by RTL8211F)

With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
and PHY_INTERFACE_MODE_RGMII_TXID.
Additionally we now explicity disable the TX-delay, which seems to be
enabled automatically after a hard-reset of the PHY (by triggering it's
reset pin) to get a consistent state (as defined by the phy-mode).

This fixes a compatibility problem with some SoCs where the TX-delay was
also added by the MAC. With the TX-delay being applied twice the TX
clock was off and TX traffic was broken or very slow (<10Mbit/s) on
1000Mbit/s links.

phy: Centralize setting driver module owner

2016-01-07T19:31:27+00:00

Rather than have each driver set the driver owner field, do it once in
the core code. This will also help with later changes, when the device
structure will move.

net: phy: realtek: register/unregister multiple drivers properly

2014-06-11T22:17:27+00:00

Using phy_drivers_register/_unregister functions is proper way to
handle multiple PHY drivers registration. For Realtek PHY drivers
module, it fixes incomplete current error-handlings up and adds
missed unregistration for the RTL8201CP driver.

phylib: Support registering a bunch of drivers

2012-07-09T07:10:56+00:00

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.

Tested with broadcom.c
All others compile-tested.
