[PATCH net-next v2 0/9] Add support for OPEN Alliance 10BASE-T1x MACPHY Serial Interface

[Parthiban Veerasooran <Parthiban.Veerasooran@microchip.com>]

This patch series contain the below updates,
- Adds support for OPEN Alliance 10BASE-T1x MACPHY Serial Interface in the
  net/ethernet/oa_tc6.c.
- Adds driver support for Microchip LAN8650/1 Rev.B0 10BASE-T1S MACPHY
  Ethernet driver in the net/ethernet/microchip/lan865x.c.

Changes:
v2:
- Removed RFC tag.
- OA TC6 framework configured in the Kconfig and Makefile to compile as a
  module.
- Kerneldoc headers added for all the API methods exposed to MAC driver.
- Odd parity calculation logic updated from the below link,
  https://elixir.bootlin.com/linux/latest/source/lib/bch.c#L348
- Control buffer memory allocation moved to the initial function.
- struct oa_tc6 implemented as an obaque structure.
- Removed kthread for handling mac-phy interrupt instead threaded irq is
  used.
- Removed interrupt implementation for soft reset handling instead of
  that polling has been implemented.
- Registers name in the defines changed according to the specification
  document.
- Registers defines are arranged in the order of offset and followed by
  register fields.
- oa_tc6_write_register() implemented for writing a single register and
  oa_tc6_write_registers() implemented for writing multiple registers.
- oa_tc6_read_register() implemented for reading a single register and
  oa_tc6_read_registers() implemented for reading multiple registers.
- Removed DRV_VERSION macro as git hash provided by ethtool.
- Moved MDIO bus registration and PHY initialization to the OA TC6 lib.
- Replaced lan865x_set/get_link_ksettings() functions with
  phy_ethtool_ksettings_set/get() functions.
- MAC-PHY's standard capability register values checked against the
  user configured values.
- Removed unnecessary parameters validity check in various places.
- Removed MAC address configuration in the lan865x_net_open() function as
  it is done in the lan865x_probe() function already.
- Moved standard registers and proprietary vendor registers to the
  respective files.
- Added proper subject prefixes for the DT bindings.
- Moved OA specific properties to a separate DT bindings and corrected the
  types & mistakes in the DT bindings.
- Inherited OA specific DT bindings to the LAN865x specific DT bindings.
- Removed sparse warnings in all the places.
- Used net_err_ratelimited() for printing the error messages.
- oa_tc6_process_rx_chunks() function and the content of oa_tc6_handler()
  function are split into small functions.
- Used proper macros provided by network layer for calculating the
  MAX_ETH_LEN.
- Return value of netif_rx() function handled properly.
- Removed unnecessary NULL initialization of skb in the
  oa_tc6_rx_eth_ready() function removed.
- Local variables declaration ordered in reverse xmas tree notation.
