035d8483ac net: eth-phy: manage subnode mdio0
Bind any subnode with name beginning by mdio, mdio0 for example,
and not only the "mdio" as namei of subnode.

880ecb09b9 net: eth-phy: use dev_dbg and log_notice
Replace debug trace and printf to log macros:
- debug() replaced by dev_dbg() when device is available, this macro
indicate the device name since commit ceb70bb870 ("dm: Print device
name in dev_xxx like Linux")
- printf() replaced by log_notice() to allow  dispatch to log backends.

d33982d5bc net: eth-phy: add support of device tree configuration for gpio reset
The gpio reset and the assert or deassert delay are defined in generic
binding of the ethernet phy in Linux:
Documentation/devicetree/bindings/net/ethernet-phy.yaml

  reset-gpios:
    maxItems: 1
    description:
      The GPIO phandle and specifier for the PHY reset signal.

  reset-assert-us:
    description:
      Delay after the reset was asserted in microseconds. If this
      property is missing the delay will be skipped.

  reset-deassert-us:
    description:
      Delay after the reset was deasserted in microseconds. If
      this property is missing the delay will be skipped.

This patch adds the parsing of this common DT properties in the
u-class "eth_phy_generic", used by default in the associated driver
"eth_phy_generic_drv"

This parsing function eth_phy_of_to_plat can be reused by other
ethernet phy drivers for this uclass UCLASS_ETH_PHY.

0fd3d91152 dm: Use access methods for dev/uclass private data
Most drivers use these access methods but a few do not. Update them.

In some cases the access is not permitted, so mark those with a FIXME tag
for the maintainer to check.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

5fe419ef2a net: Add eth phy generic driver for shared MDIO
For dual ethernet controllers, the HW design may connect ETH phys to
one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.

To resolve this problem, introduce an eth phy generic driver and uclass.

After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.

When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.
