of/net/mdio-gpio: Fix pdev->id issue when using devicetrees.

2012-11-19T23:57:07+00:00

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-"

Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.

Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.

So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

Revert "drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before mdiobus_free"

2012-11-15T03:32:15+00:00

This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e.

As pointed out by Ben Hutchings, this change is not correct.

mdiobus_unregister() can't be called if the bus isn't registered yet,
however this change can result in situations which cause that to
happen.

Part of the confusion here revolves around the fact that the
callers of this module control registration/unregistration,
rather than the module itself.

drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before mdiobus_free

2012-11-03T01:36:06+00:00

Based on commit b27393aecf66199f5ddad37c302d3e0cfadbe6c0

Calling mdiobus_free without calling mdiobus_unregister causes
BUG_ON(). This patch fixes the issue.

The semantic patch that found this issue(http://coccinelle.lip6.fr/):

Ensure that of_mdio_find_bus() matches the prototype in the header (and
stop sparse complaining) by including the header with the prototype.

net: phy: smsc: Implement PHY config_init for LAN87xx

2012-09-27T22:28:30+00:00

The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving
capability. Enabling it leads to the PHY not being able to detect Link when
cold-started without cable connected. Thus, make sure this is disabled.

phy/micrel: Rename KS80xx to KSZ80xx

2012-09-24T19:54:33+00:00

There is no such part as KS8001, KS8041 or KS8051. There are only
KSZ8001, KSZ8041 and KSZ8051. Rename these parts as such to match
the Micrel naming.

phy/micrel: Implement support for KSZ8021

2012-09-24T19:54:32+00:00

The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.
