This series prevents the UCLASS_ETH device "node" field overwriting
by some network drivers when Ethernet PHYs are linked to UCLASS_ETH device using
"phy-handle" DT property and when Ethernet PHY driver needs to read some
additional information from DT (like dp83867).
It fixes following cases:
- network drivers
priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev,
priv->interface);
<-- phydev is connected to dev which is UCLASS_ETH device
if (priv->phy_of_handle > 0)
dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle);
<-- phydev->dev->node is overwritten by phy-handle DT node
- PHY driver in .config() callback
int node = dev_of_offset(dev);
<-- PHY driver uses overwritten dev->node
const void *fdt = gd->fdt_blob;
if (fdtdec_get_bool(fdt, node, "property"))
...
As result, UCLASS_ETH device can't be used any more for DT accessing.
It adds new field ofnode node to struct phy_device and updates TI CPSW and
zynq_gem drivers to use it.
zynq_gem.c, xilinx_phy.c changes only build tested.
Changes in v2:
- struct phy_device->node field initialization added to phy_device_create()
Dependency:
This series has dependency from
https://patchwork.ozlabs.org/cover/936370/
due to possible merge conflicts
PS: Not sure if any other Net drivers need to be updated,
at least I've not found any.
