phylib: Allow early-out in phy_change

2009-04-13T21:51:23+00:00

Marvell 88E1121R Dual PHY device can be hardware-configured to use shared interrupt pin for both PHY ports. For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt. So check for interrupt originator in phy_change() to allow early-out. Signed-off-by: Anatolij Gustschin Signed-off-by: David S. Miller

phylib: convert state_queue work to delayed_work

2009-03-13T22:41:19+00:00

It closes a race in phy_stop_machine when reprogramming of phy_timer (from phy_state_machine) happens between del_timer_sync and cancel_work_sync. Without this change it could lead to crash if phy_device would be freed after phy_stop_machine (timer would fire and schedule freed work).

phy: power management support

2008-11-29T00:24:56+00:00

This patch adds the power management support into the physical abstraction layer. Suspend and resume functions respectively turns on/off the bit 11 into the PHY Basic mode control register. Generic PHY device starts supporting PM. In order to support the wake-on LAN and avoid to put in power down the PHY device, the MDIO is aware of what the Ethernet device wants to do. Voluntary, no CONFIG_PM defines were added into the sources. Also generic suspend/resume functions are exported to allow other drivers use them (such as genphy_config_aneg etc.). Within the phy_driver_register function, we need to remove the memset. It overrides the device driver owner and it is not good. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S. Miller

phylib: add mdiobus_{read,write}

2008-10-08T23:38:41+00:00

Add mdiobus_{read,write} routines to allow direct reading/writing of registers on an mii bus without having to go through the PHY abstraction, and make phy_{read,write} use these primitives. Signed-off-by: Lennert Buytenhek Signed-off-by: David S. Miller

phylib: give mdio buses a device tree presence

2008-10-08T23:33:40+00:00

Introduce the mdio_bus class, and give each 'struct mii_bus' its own 'struct device', so that mii_bus objects are represented in the device tree and can be found by querying the device tree. Signed-off-by: Lennert Buytenhek Acked-by: Andy Fleming Signed-off-by: David S. Miller

phylib: move to dynamic allocation of struct mii_bus

2008-10-08T23:29:57+00:00

This patch introduces mdiobus_alloc() and mdiobus_free(), and makes all mdio bus drivers use these functions to allocate their struct mii_bus'es dynamically. Signed-off-by: Lennert Buytenhek Signed-off-by: David S. Miller Acked-by: Andy Fleming

phylib: rename mii_bus::dev to mii_bus::parent

2008-10-08T23:27:49+00:00

In preparation of giving mii_bus objects a device tree presence of their own, rename struct mii_bus's ->dev argument to ->parent, since having a 'struct device *dev' that points to our parent device conflicts with introducing a 'struct device dev' representing our own device.

phylib: allow incremental scanning of an mii bus

2008-09-19T03:13:54+00:00

This patch splits the bus scanning code in mdiobus_register() off into a separate function, and makes this function available for calling from external code. This allows incrementally scanning an mii bus, e.g. as information about which addresses are 'safe' to scan becomes available. Signed-off-by: Lennert Buytenhek Acked-by: Andy Fleming

phylib: Fix some sparse warnings

2008-05-06T16:01:41+00:00

Declared some things static, declared some things in the header. Signed-off-by: Andy Fleming Signed-off-by: Jeff Garzik

phylib: Add support for board-level PHY fixups

2008-04-25T06:08:52+00:00

Sometimes the specific interaction between the platform and the PHY requires special handling. For instance, to change where the PHY's clock input is, or to add a delay to account for latency issues in the data path. We add a mechanism for registering a callback with the PHY Lib to be called on matching PHYs when they are brought up, or reset. Signed-off-by: Andy Fleming Signed-off-by: Jeff Garzik
