net: phy: realtek: Dummy IRQ calls for RTL8366RB

2019-02-24T02:45:28Z

This fixes a regression introduced by commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7 "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

net: phy: don't use locking in phy_is_started

2019-02-14T17:04:55Z

Russell suggested to remove the locking from phy_is_started() because the read is atomic anyway and actually the locking may be more misleading.

net: phy: phy driver features are mandatory

2019-01-19T18:03:08Z

Since phy driver features became a link_mode bitmap, phy drivers that don't have a list of features configured will cause the kernel to crash when probed. Prevent the phy driver from registering if the features field is missing.

net: phy: Add missing features to PHY drivers

2019-01-16T23:41:02Z

The bcm87xx and micrel driver has PHYs which are missing the .features value. Add them. The bcm87xx is a 10G FEC only PHY. Add the needed features definition of this PHY.

phy.h: fix obvious errors in doc and kerneldoc content

2018-12-28T00:29:31Z

1) note that gianfar_phy.c was removed years ago 2) fix obvious copy and paste error in regular doc 3) change regular doc into kerneldoc for phy_modes() Signed-off-by: Robert P. J. Day Signed-off-by: David S. Miller

net: phy: improve phy state checking

2018-12-18T23:11:07Z

Add helpers phy_is_started() and __phy_is_started() to avoid open-coded checks whether PHY has been started. To make the check easier move PHY_HALTED before PHY_UP in enum phy_state. Further improvements: phy_start_aneg(): Return -EBUSY and print warning if function is called from a non-started state (DOWN, READY, HALTED). Better check because function is exported and drivers may use it incorrectly. phy_interrupt(): Return IRQ_NONE also if state is DOWN or READY. We should never receive an interrupt in one of these states, but better play safe. phy_stop(): Just return and print a warning if PHY is in a non-started state. This warning should help to identify drivers with unbalanced calls to phy_start() / phy_stop(). phy_state_machine(): Schedule state machine run only if PHY is in a started state. E.g. if state is READY we don't need the state machine, it will be started by phy_start(). v2: - don't use __func__ within phy_warn_state v3: - use WARN() instead of printing error message to facilitate debugging Signed-off-by: Heiner Kallweit Reviewed-by: Florian Fainelli Signed-off-by: David S.

net: phy: Convert u32 phydev->lp_advertising to linkmode

2018-11-11T18:10:01Z

Convert phy drivers to report the link partner advertised modes using a linkmode bitmap. This allows them to report the higher speeds which don't fit in a u32. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: ethernet: Convert phydev advertize and supported from u32 to link mode

2018-11-11T18:10:01Z

There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: remove states PHY_STARTING and PHY_PENDING

Both states aren't used. Most likely they result from an idea that never materialized. So remove them. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller
