net: phy: fix auto-negotiation stall due to unavailable interrupt

2017-05-03T15:37:42+00:00

[ Upstream commit f555f34fdc586a56204cd16d9a7c104ec6cb6650 ] The Ethernet link on an interrupt driven PHY was not coming up if the Ethernet cable was plugged before the Ethernet interface was brought up. The patch trigger PHY state machine to update link state if PHY was requested to do auto-negotiation and auto-negotiation complete flag already set. During power-up cycle the PHY do auto-negotiation, generate interrupt and set auto-negotiation complete flag. Interrupt is handled by PHY state machine but doesn't update link state because PHY is in PHY_READY state. After some time MAC bring up, start and request PHY to do auto-negotiation. If there are no new settings to advertise genphy_config_aneg() doesn't start PHY auto-negotiation. PHY continue to stay in auto-negotiation complete state and doesn't fire interrupt. At the same time PHY state machine expect that PHY started auto-negotiation and is waiting for interrupt from PHY and it won't get it.

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() Signed-off-by: Woojung Huh Signed-off-by: David S. Miller

net: phy: add mdix_ctrl to hold the user configuration.

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. Signed-off-by: Raju Lakkaraju Signed-off-by: David S. Miller

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.

net: phy: leds: add support for led triggers on phy link state change

2016-10-18T15:56:31+00:00

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.
