NET: phy_device, fix lock imbalance

2009-07-14T19:03:39+00:00

Don't forget to unlock a mutex in phy_scan_fixups on a fail path. Signed-off-by: Jiri Slaby Signed-off-by: David S. Miller

phy_device: fix parameter name in kernel-doc

Fix kernel-doc parameter name in phy_device.c. Signed-off-by: Randy Dunlap Signed-off-by: David S. Miller

phylib: add *_direct() variants of phy_connect and phy_attach functions

2009-04-27T09:53:46+00:00

Add phy_connect_direct() and phy_attach_direct() functions so that drivers can use a pointer to the phy_device instead of trying to determine the phy's bus_id string. This patch is useful for OF device tree descriptions of phy devices where the driver doesn't need or know what the bus_id value in order to get a phy_device pointer.

phylib: rework to prepare for OF registration of PHYs

2009-04-27T09:53:45+00:00

This patch makes changes in preparation for supporting open firmware device tree descriptions of MDIO busses. Changes include: - Cleanup handling of phy_map[] entries; they are already NULLed when registering and so don't need to be re-cleared, and it is good practice to clear them out when unregistering. - Split phy_device registration out into a new function so that the OF helpers can do two stage registration (separate allocation and registration steps).

phylib: Fix Freescale TBI PHY detection

2009-01-14T22:38:02+00:00

Freescale on-chip TBI PHYs reports PHY ID as 0x0, but as of commit 3ee82383f0098a2e13acc8cf1be8e47512f41e5a Author: Giulio Benetti Date: Thu Nov 13 21:53:13 2008 +0000 phy: fix phy address bug PHYID returns 0xffff and not 0xffffffff when not found and in some case(at91sam9263) 0x0. Maybe this patch could be useful. phy_device.c treats PHY ID == 0x0 as bogus IDs, and that results in gianfar driver failure to see the TBI PHYs. This code snippet triggers: if (!priv->tbiphy) { printk(KERN_WARNING "SGMII mode requires that the device " "tree specify a tbi-handle\n"); return; } Although tbi-handle is specified in the device tree. Btw, technically PHY ID == 0x0 is a valid ID (if we ever see a PHY manufactured by Xerox :-). Signed-off-by: Anton Vorontsov Acked-by: Andy Fleming Signed-off-by: David S. Miller

net: PHYLIB mdio fixes #2

2008-12-26T00:50:41+00:00

The PHYLIB mdio code has more problems in error paths: - mdiobus_release can be called before bus->state is set to MDIOBUS_REGISTERED - mdiobus_scan allocates resources which need to be freed - the comment is wrong, the resistors used are actually pull-ups.

phylib: Remove unnecessary "reset" fixups in genphy_setup_forced

2008-12-16T23:39:48+00:00

genphy_setup_forced hasn't actually reset the PHY for a long time, but a comment to that effect remained in the code, so code continued to act as if it *had* reset the PHY, and called the necessary fixup functions to respond to a PHY reset. With no reset, those functions are no longer needed, so we remove them. Signed-off-by: Andy Fleming Signed-off-by: David S. Miller

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

phy: fix phy_id detection also for broken hardware.
