net: phy: replace phy_drivers_register calls

2014-11-12T18:52:53+00:00

Replace module init/exit which only calls phy_drivers_register with
module_phy_driver macro.

Tested using Micrel driver, and otherwise compile-tested only.

net: phy: at803x: Add support for hardware reset

2014-06-21T22:50:00+00:00

The AT8030 will enter a FIFO error mode if a packet is transmitted while
the cable is unplugged. This hardware issue is acknowledged by the
vendor, and the only proposed solution is to conduct a hardware reset
via the external pin each time the link goes down. There is apparantly
no way to fix up the state via the register set.

This patch adds support for reading a 'reset-gpios' property from the DT
node of the PHY. If present, this gpio is used to apply a hardware reset
each time a 'link down' condition is detected. All relevant registers
are read out before, and written back after the reset cycle.

Doing this every time the link goes down might seem like overkill, but
there is unfortunately no way of figuring out whether the PHY is in
such a lock-up state. Hence, this is the only way of reliably fixing up
things.

net: phy: at803x: use #defines for supported PHY ids

2014-06-21T22:50:00+00:00

This removes magic values from two tables and also allows us to match
against specific PHY models at runtime.

net/phy: Remove return value for void function

This was caught when using a spatch (aka. coccinelle) script

Use the generic bits from genphy_config_init() instead of implementing
the same functionality again.

phy/at8031: enable at8031 to work on interrupt mode

2014-03-29T22:20:30+00:00

The at8031 can work on polling mode and interrupt mode.
Add ack_interrupt and config intr funcs to enable
interrupt mode for it.

net: phy: at803x: add suspend/resume callbacks

2013-09-27T21:28:32+00:00

When WOL is enabled, the chip can't be put into power-down (BMCR_PDOWN)
mode, as that will also switch off the MAC, which consequently leads to
a link loss.

Use BMCR_ISOLATE in that case, which will at least save us some
milliamperes in comparison to normal operation mode.
