net: ethernet: Use device_get_match_data()

2023-10-13T09:04:53+00:00

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

net: ethernet: altera: Convert to platform remove callback returning void

2023-09-20T08:06:37+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

net: altera-tse: make ALTERA_TSE depend on HAS_IOMEM

2023-08-18T17:18:51+00:00

On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common than
PCI devices.  Hence it could have a fully functional s390 kernel with
CONFIG_PCI=n, then the relevant iomem mapping functions [including
ioremap(), devm_ioremap(), etc.] are not available.

Here let ALTERA_TSE depend on HAS_IOMEM so that it won't be built to cause
below compiling error if PCI is unset:

------
ERROR: modpost: "devm_ioremap" [drivers/net/ethernet/altera/altera_tse.ko] undefined!
------

net: altera_tse: explicitly disable autoscan on the regmap-mdio bus

2023-06-07T20:30:12+00:00

Set the .autoscan flag to false on the regmap-mdio bus, to avoid using a
random uninitialized value. We don't want autoscan in this case as the
mdio device is a PCS and not a PHY.

net: altera_tse: Use the correct Kconfig option for the PCS_LYNX dependency

Use the correct Kconfig dependency for altera_tse as PCS_ALTERA_TSE was
replaced by PCS_LYNX.

net: altera-tse: Initialize local structs before using it

2023-06-07T20:30:11+00:00

The regmap_config and mdio_regmap_config objects needs to be zeroed before
using them. This will cause spurious errors at probe time as config->pad_bits
is containing random uninitialized data.

net: ethernet: altera-tse: Convert to mdio-regmap and use PCS Lynx

2023-06-05T08:56:36+00:00

The newly introduced regmap-based MDIO driver allows for an easy mapping
of an mdiodevice onto the memory-mapped TSE PCS, which is actually a
Lynx PCS.

Convert Altera TSE to use this PCS instead of the pcs-altera-tse, which
is nothing more than a memory-mapped Lynx PCS.

net: altera: tse: remove mac_an_restart() function

2023-05-22T10:20:35+00:00

The mac_an_restart() method will only be called if the driver sets
legacy_pre_march2020, which the altera tse driver does not do.
Therefore, providing a stub is unnecessary.
