76f60470a1 realtek: Fix bug when accessing external PHYs on SoCs older than Revision C
RTL8393 SoCs older than Revision C hang on accesses to PHYs with PHY address
larger or equal to the CPU-port (52). This will make scanning the MDIO bus
hang forever. Since the RTL8390 platform does not support more than
52 PHYs, return -EIO for phy addresses >= 52. Note that the RTL8390 family
of SoCs has a fixed mapping between port number and PHY-address.

9ae927febd realtek: Fix bug in VLAN ingress and egress filtering
The ingress filter registers use 2 bits for each port to define the filtering
state, whereas the egress filter uses 1 bit. So for for the ingress filter
the register offset for a given port is:
(port >> 4) << 4: since there are 16 entries in a register of 32 bits
and for the egress filter:
(port >> 5) << 4: since there are 32 entries in a register of 32 bits

3810e89729 realtek: ensure output drivers are enabled in RTL8231
The bootloader can leave the GPIO expander in a state which doesn't have
output drivers enabled so GPIOs will properly work for input but output
operations will have no effect.

To avoid disrupting the boot in case the bootloader left direction and
data registers in an inconsistent state (e.g. pulling SoC's reset to 0)
reconfigure everything as input.

2e676c05dc realtek: fix kernel panic in DSA driver for 5.10
dsa_to_port function in 5.10 returns dsa_port from the port list in
dsa_switch_tree, but the tree is built when the switch is registered
by dsa_register_switch and it's null in rtl83xx_mdio_probe.

So, we need to use dsa_to_port after the registration of the switch.
