Ethernet phy like dp83867 is using strapping resistors to setup PHY
address. On Xilinx boards strapping is setup on wires which are connected
to SOC where internal pull ups/downs influnce phy address. That's why there
is a need to setup pins properly (via pinctrl driver for example) and then
perform phy reset. I can be workarounded by reset gpio done for mdio bus
but this is not working properly when multiply phys sitting on the same
bus. That's why it needs to be done via ethernet-phy-id driver where dt
binding has gpio reset per phy.
DT binding is available here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-phy.yaml
The driver is are reading the vendor and device id from valid phy node
using ofnode_read_eth_phy_id() and creating a phy device.
Kconfig PHY_ETHERNET_ID symbol is used because not every platform has gpio
support.

Some boards like the Beacon RZ/G2 SOM use either flags for
tx-internal-delay-ps, rx-internal-delay-ps or rgmii-rxid.
In Linux the APSR_RDM flag is set when either rx-internal-delay-ps
is set or the mode is rgmii-rxid, and the APSR_TDM is set when
tx-internal-delay-ps is found or rgmii-txid is set, and both
are set if rgmii-id is set.
The ravb driver in U-Boot driver was missing rgmii-rxid support,
so add that support in a similar fashion to what is done in Linux.

Since same DT is used in Linux and U-Boot we need to workaround this

ignore the gem pointing to phy directly.

priv->phy_of_node only if it is not valid node.

This patch changes the register in the fman_mdio and fsl_ls_mdio

The sja1105_check_device_id() function contains logic to work without
changing the device tree on reworked boards, one of which I have (the
NXP LS1021A-TSN normally has a SJA1105T, but I have a version with a
resoldered SJA1105Q which is pin compatible). This logic is taken from
the Linux driver.
However this logic gets shortcircuited in U-Boot by an earlier check for
the exact device ID specified in the device tree. So the reworked board
does not probe the SJA1105Q switch. Remove this duplicated logic and let
the automatic device ID detection do its job.

The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for
(ret != -ENOENT) and if the condition is true, returns ret outright.
This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.
Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

It turns out that in custom designs if the system is reset
multiple times in conjunction with a slight increase in external
temperature, the felix switch starts to behave in a strange way:
packets are no longer received on the ENECT interface connected
to the L2switch internal port (the TX side of internal port stops working
or the packets do not reach there. It is not very clear where
the packets remain blocked. None of the counters points to a disruption
in the L2switch)
The issue is not reproducible on NXP reference designs.
It was observed that by adding the switch core reset, the problem
goes aways, even if intensive testing in temperature chambers
is applied.
The current patch performs soft reset on the switch core to ensure proper
operation of the L2switch.
