ethernet: Make OA_TC6 config symbol invisible

Commit aa58bec064ab1622 ("net: ethernet: oa_tc6: implement register
write operation") introduced a library that implements the OPEN Alliance
TC6 10BASE-T1x MAC-PHY Serial Interface protocol for supporting
10BASE-T1x MAC-PHYs.

There is no need to ask the user about enabling this library, as all
drivers that use it select the OA_TC6 symbol. Hence make the symbol
invisible, unless when compile-testing.

net: ethernet: oa_tc6: implement register write operation

Implement register write operation according to the control communication
specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface
document. Control write commands are used by the SPI host to write
registers within the MAC-PHY. Each control write commands are composed of
a 32 bits control command header followed by register write data.

The MAC-PHY ignores the final 32 bits of data from the SPI host at the
end of the control write command. The write command and data is also
echoed from the MAC-PHY back to the SPI host to enable the SPI host to
identify which register write failed in the case of any bus errors.
Control write commands can write either a single register or multiple
consecutive registers. When multiple consecutive registers are written,
the address is automatically post-incremented by the MAC-PHY. Writing to
any unimplemented or undefined registers shall be ignored and yield no
effect.

net: ethernet: adi: Add ADIN1110 support

The ADIN1110 is a low power single port 10BASE-T1L MAC-PHY
designed for industrial Ethernet applications. It integrates
an Ethernet PHY core with a MAC and all the associated analog
circuitry, input and output clock buffering.

ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registers
can be accessed through the MDIO MAC registers.
We are registering an MDIO bus with custom read/write in order
to let the PHY to be discovered by the PAL. This will let
the ADIN1100 Linux driver to probe and take control of
the PHY.

The ADIN2111 is a low power, low complexity, two-Ethernet ports
switch with integrated 10BASE-T1L PHYs and one serial peripheral
interface (SPI) port.

The device is designed for industrial Ethernet applications using
low power constrained nodes and is compliant with the IEEE 802.3cg-2019
Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE).
The switch supports various routing configurations between
the two Ethernet ports and the SPI host port providing a flexible
solution for line, daisy-chain, or ring network topologies.

The ADIN2111 supports cable reach of up to 1700 meters with ultra
low power consumption of 77 mW. The two PHY cores support the
1.0 V p-p operating mode and the 2.4 V p-p operating mode defined
in the IEEE 802.3cg standard.

The device integrates the switch, two Ethernet physical layer (PHY)
cores with a media access control (MAC) interface and all the
associated analog circuitry, and input and output clock buffering.

The device also includes internal buffer queues, the SPI and
subsystem registers, as well as the control logic to manage the reset
and clock control and hardware pin configuration.

Access to the PHYs is exposed via an internal MDIO bus. Writes/reads
can be performed by reading/writing to the ADIN2111 MDIO registers
via SPI.

On probe, for each port, a struct net_device is allocated and
registered. When both ports are added to the same bridge, the driver
will enable offloading of frame forwarding at the hardware level.

Driver offers STP support. Normal operation on forwarding state.
Allows only frames with the 802.1d DA to be passed to the host
when in any of the other states.

When both ports of ADIN2111 belong to the same SW bridge a maximum
of 12 FDB entries will offloaded by the hardware and are marked as such.

ASIX AX88796[1] is a versatile ethernet adapter chip, that can be
connected to a CPU with a 8/16-bit bus or with an SPI. This driver
supports SPI connection.

The driver has been ported from the vendor kernel for ARTIK5[2]
boards. Several changes were made to adapt it to the current kernel
which include:

+ updated DT configuration,
+ clock configuration moved to DT,
+ new timer, ethtool and gpio APIs,
+ dev_* instead of pr_* and custom printk() wrappers,
+ removed awkward vendor power managemtn.
+ introduced ethtool tunable to control SPI compression

The other ax88796 driver is for NE2000 compatible AX88796L chip. These
chips are not compatible. Hence, two separate drivers are required.
