This small series add the initial support for the Airoha AN8855 Switch.
It's a 5 port Gigabit Switch with SGMII/HSGMII upstream port.
This is starting to get in the wild and there are already some router
having this switch chip.
It's conceptually similar to mediatek switch but register and bits
are different. And there is that massive Hell that is the PCS
configuration.
Saddly for that part we have absolutely NO documentation currently.
There is this special thing where PHY needs to be calibrated with values
from the switch efuse. (the thing have a whole cpu timer and MCU)
>From v8 Driver is now evaluated with Kernel selftest scripts for DSA:

Changes v8:
- Add port Fast Age support
- Add support for Port Isolation
- Use correct register for Learning Disable
- Add support for Ageing Time OP
- Set default PVID to 0 by default
- Add mdb OPs
- Add port change MTU
- Fix support for Upper VLAN
Changes v7:
- Fix devm_dsa_register_switch wrong export symbol
Changes v6:

- Reset fdb struct in fdb_dump
- Drop support_asym_pause in port_enable
- Add define for get_phy_flags
- Fix bug for port not inititially part of a bridge
(in an8855_setup the port matrix was always cleared but
the CPU port was never initially added)
- Disable learning and flood for user port by default
- Set CPU port to flood and learning by default
- Correctly AND force duplex and flow control in an8855_phylink_mac_link_up
- Drop RGMII from pcs_config
- Check ret in "Disable AN if not in autoneg"
- Use devm_mutex_init
- Fix typo for AN8855_PORT_CHECK_MODE
- Better define AN8855_STP_LISTENING = AN8855_STP_BLOCKING
- Fix typo in AN8855_PHY_EN_DOWN_SHIFT
- Use paged helper for PHY
- Skip calibration in config_init if priv not defined
Changes v3:
- Out of RFC
- Switch PHY code to select_page API
- Better describe masks and bits in PHY driver for ADC register
- Drop raw values and use define for mii read/write
- Switch to absolute PHY address
- Replace raw values with mask and bits for pcs_config
- Fix typo for ext-surge property name
- Drop support for relocating Switch base PHY address on the bus
Changes v2:
- Drop mutex guard patch
- Drop guard usage in DSA driver
- Use __mdiobus_write/read
- Check return condition and return errors for mii read/write
- Fix wrong logic for EEE
- Fix link_down (don't force link down with autoneg)
- Fix forcing speed on sgmii autoneg
- Better document link speed for sgmii reg
- Use standard define for sgmii reg
- Imlement nvmem support to expose switch EFUSE
- Rework PHY calibration with the use of NVMEM producer/consumer
- Update DT with new NVMEM property
- Move aneg validation for 2500-basex in pcs_config
- Move r50Ohm table and function to PHY driver
