2008-11-16phylib: make mdio-gpio work without OF (v4)Paulius Zaleckas
make mdio-gpio work with non OpenFirmware gpio implementation. Aditional changes to mdio-gpio: - use gpio_request() and gpio_free() - place irq[] array in struct mdio_gpio_info - add module description, author and license - add note about compiling this driver as module - rename mdc and mdio function (were ugly names) - change MII to MDIO in bus name - add __init __exit to module (un)loading functions - probe fails if no phys added to the bus - kzalloc bitbang with sizeof(*bitbang) Changes since v3: - keep bus naming "%x" to be compatible with existing drivers. Changes since v2: - more #ifdefs reduction - platform driver will be registered on OF platforms also - unified platform and OF bus_id to phy%i Changes since v1: - removed NO_IRQ - reduced #idefs Laurent, please test this driver under OF.

2008-11-14phylib: fix premature freeing of struct mii_busLennert Buytenhek
Commit 46abc02175b3c246dd5141d878f565a8725060c9 ("phylib: give mdio buses a device tree presence") added a call to device_unregister() in a situation where the caller did not intend for the device to be freed yet, but apart from just unregistering the device from the system, device_unregister() does an additional put_device() that is intended to free it. The right function to use in this situation is device_del(), which unregisters the device from the system like device_unregister() does, but without dropping the reference count an additional time.

2008-11-06SMSC LAN911x and LAN921x vendor driverSteve Glendinning
Attached is a driver for SMSC's LAN911x and LAN921x families of embedded ethernet controllers. There is an existing smc911x driver in the tree; this is intended to replace it. Dustin McIntire (the author of the smc911x driver) has expressed his support for switching to this driver. This driver contains workarounds for all known hardware issues, and has been tested on all flavours of the chip on multiple architectures. This driver now uses phylib, so this patch also adds support for the device's internal phy Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: Bahadir Balban <Bahadir.Balban@arm.com> Signed-off-by: Dustin Mcintire <dustin@sensoria.com> Signed-off-by: Bill Gatliff <bgat@billgatliff.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-10-09phylib: two dynamic mii_bus allocation fallout fixesLennert Buytenhek
1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be converted over to mdiobus_{alloc,free}(). 2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its struct fixed_mdio_bus and then use container_of() to go from the former to the latter. Since mii bus structures are no longer embedded, we need to do something like use the mii bus private pointer to go from mii_bus to fixed_mdio_bus instead.

2008-10-08PHY: Avoid unnecessary aneg restartsTrent Piepho
The PHY's aneg is configured and restarted whenever the link is brought up, e.g. when DHCP is started after the kernel has booted. This can take the link down for several seconds while auto-negotiation is redone. If the advertised features haven't changed, then it shouldn't be necessary to bring down the link and start auto-negotiation over again. genphy_config_advert() is enhanced to return 0 when the advertised features haven't been changed and >0 when they have been. genphy_config_aneg() then uses this information to not call genphy_restart_aneg() if there has been no change.
