stmmac: fix MDIO settings

2016-04-01T18:38:59+00:00

Initially the phy_bus_name was added to manipulate the
driver name but it was recently just used to manage the
fixed-link and then to take some decision at run-time.
So the patch uses the is_pseudo_fixed_link and removes
the phy_bus_name variable not necessary anymore.

The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using
fixed-link).

Revert "stmmac: Fix 'eth0: No PHY found' regression"

2016-04-01T18:38:58+00:00

This reverts commit 88f8b1bb41c6208f81b6a480244533ded7b59493.
due to problems on GeekBox and Banana Pi M1 board when
connected to a real transceiver instead of a switch via
fixed-link.

stmmac: Fix 'eth0: No PHY found' regression

2016-03-03T20:02:05+00:00

This patch manages the case when you have an Ethernet MAC with
a "fixed link", and not connected to a normal MDIO-managed PHY device.

The test of phy_bus_name was not helpful because it was never affected
and replaced by the mdio test node.

stmmac: rework DMA bus setting and introduce new platform AXI structure

2016-03-02T19:21:30+00:00

This patch restructures the DMA bus settings and this is done
by introducing a new platform structure used for programming
the AXI Bus Mode Register inside the DMA module.
This structure can be populated from device-tree as documented in the
binding txt file.

After initializing the DMA, the AXI register can be optionally tuned
for platform drivers based.
This patch also reworks some parameters to make coherent the DMA
configuration now that AXI register is introduced.
For example, the burst_len is managed by using the mentioned axi
support above; so the snps,burst-len parameter has been removed.
It makes sense to provide the AAL parameter from DT to Address-Aligned
Beats inside the Register0 and review the PBL settings when initialize
the engine.

For PCI glue, rebuilding the story of this setting, it
was added to align a configuration so not for fixing some
known problem. No issue raised after this patch.
It is safe to use the default burst length instead of
tuning it to the maximum value

stmmac: remove setup/free glue callbacks

2015-07-29T07:13:25+00:00

As all dwmac-* drivers have been converted to have a proper probe
function the setup callback can now be removed. Also remove the
free callback that wasn't used by any driver.

New dwmac-* drivers should implement standard probe and remove
functions to preform any needed setup and teardown.

stmmac: remove unused stmmac_of_data struct

2015-07-29T07:13:24+00:00

As dwmac-* drivers that need OF match have been converted
to use their own internal OF match data structure this can
now be removed.

stmmac: drop custom_* fields from plat_stmmacenet_data

2015-07-21T03:45:57+00:00

Both of these fields are unused and has been unused since they
were added 3 and 5 years ago. Drop them since they are clearly
not very useful.

stmmac: add phy-handle support to the platform layer

2015-05-31T00:04:36+00:00

On stmmac driver, PHY specification in device-tree was done using the
non-standard property "snps,phy-addr". Specifying a PHY on a different
MDIO bus that the one within the stmmac controller doesn't seem to be
possible when device-tree is used.

This change adds support for the phy-handle property, as specified in
Documentation/devicetree/bindings/net/ethernet.txt.

stmmac: Read tx-fifo-depth and rx-fifo-depth from the devicetree

2015-04-16T17:58:42+00:00

Read the tx-fifo-depth and rx-fifo-depth from the devicetree. The Synopsys
stmmac controller fifos are configurable per product instance, and the fifo
sizes are needed to configure certain features correctly such as flow control.
