* net: cpsw: Make phy its own driverSascha Hauer2019-08-281-82/+96
| | | | | | | | | | | | | | | This makes of_phy_device_connect() work properly when the phy is specified in the device tree. Without it of_mdio_find_phy() will not find the right device. It will match: bus->parent->device_node == phy_node->parent Without this patch bus->parent->device_node will be the ethernet node and phy_node->parent will be the ti,cpsw-mdio node. With the MDIO device node registered as device of its own both nodes above will be the ti,cpsw-mdio node. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: cpsw: adopt to upstream device tree changesSascha Hauer2019-07-101-6/+10
| | | | | | | | | | | | | | | | | Upstream device trees no longer have a "cpsw-phy-sel" property to find the phy_sel register, instead they have a child device of the pinctrl node compatible to "ti,am3352-phy-gmii-sel". Also the "rmii-clock-ext" property is no longer global to the cpsw but instead can be selected per slave. To adopt to these changes take the short way out for now and find the new node by its compatible and hardcode the "rmii-clock-ext" setting (which is set to true in am33xx-l4.dtsi and not overwritten by any board). This makes the cpsw driver work again. Tested on Beaglebone black board. Fixes: 1dc748b3b2 ("dts: update to v5.1-rc1") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: ethernet: cpsw: cpsw-phy-sel: Use phandle for phy selTeresa Remmet2019-02-131-6/+11
| | | | | | | | | | | | | | | With the usage of the interconnect target module hierarchy in device tree the cpsw-phy-sel node moved to the system control module. An phandle has been added instead to the device tree include. Try to use the cpsw-phy-sel phandle first then fall back looking for the cpsw-phy-sel child. This patch is based on the upstream kernel patch: 18eb8aea7fb2 ("net: ethernet: cpsw-phy-sel: prefer phandle for phy sel") Signed-off-by: Teresa Remmet <t.remmet@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | | Upstream dts files changed to the generic binding for mii phys, so we have to support it in barebox aswell. The barebox internal device trees haven't been changed, so support them until all have changed. We print a warning to add some motivation to change.

* net: cpsw: fix probe with fixed-linkAndreas Schmidt2018-03-051-4/+6
| | | | | | | | | While cpsw is probe dt, it accepts only slaves nodes with "phy_id" property. In case of fixed-link there are no "phy_id" property and probe would be failed. This patch avoid the failure due to missing "phy_id" in case of fixed-link. Signed-off-by: Andreas Schmidt <mail@schmidt-andreas.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: cpsw: Call phy_device_connect() earlierSascha Hauer2018-02-221-15/+4
| | | | | | | | | We only want to register a slave when a valid phy is available. Instead of manually calling mdiobus_scan() and phy_register_device() we can let this do from phy_device_connect() which also works for fixed phys. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: cpsw: unregister device on remove callbackSascha Hauer2015-04-281-5/+39
| | | | | | | | | | The CPSW uses DMA, so we should quiesce the device before leaving barebox. This patch unregisters the CPSW properly on the device remove callback. To do this we have to fix the error path in cpsw_slave_setup, since this function can fail and we need a known slave status in the remove function.

* net: cpsw: ignore error on slave setupSascha Hauer2015-01-061-15/+14
| | | | | | | | | | | The CPSW has two slaves. When one of them fails to setup continue anyway with the other one. This fixes a crash in the beaglebone black which only has one slave connected. The code doesn't find a phy on the second slave and bails out, but the error path is broken: It frees the private data structures which contains used resources.

* net cpsw: fix rx stability under heavy network loadChristoph Fritz2014-05-051-1/+6
| | | | | | | | | | | | RX DMA Head Descriptor Pointer can get 0 when there is a lot of traffic, which results in a timeout error. A good way to provoke this error is by sending lots of ARP requests. This patch makes sure that the RX DMA Head Descriptor Pointer is set. The origin driver, from which this is derived, already contains this fix.
