Subject: [PATCH v5 0/4] Adding the Sparx5 Serdes driver

Adding the Sparx5 Serdes driver

This series of patches provides the serdes driver for the Microchip Sparx5
ethernet switch.

The serdes driver supports the 10G and 25G serdes instances available in the
Sparx5.

The Sparx5 serdes support several interface modes with several speeds and also
allows the client to change the mode and the speed according to changing in the
environment such as changing cables from DAC to fiber.

The serdes driver is to be used by the Sparx5 switchdev driver that
will follow in subsequent series.

History:
--------
v4 -> v5:
    - Bindings:
      - Removed .yaml from compatible string
      - reg prop: removed description and added minItems
      - reg-names prop: removed description and added const name list and minItems
      - #phy-cells prop: removed description and added maxItems
    - Configuration interface
      - Removed include of linux/phy.h
      - Added include of linux/types.h
    - Driver
       - Added include of linux/phy.h

v3 -> v4:
    - Add a reg-names item to the binding description
    - Add a clocks item to the binding description
    - Removed the clock parameter from the configuration interface
    - Use the clock dt node to get the coreclock, and using that when 
      doing the actual serdes configuration
    - Added a clocks entry with a system clock reference to the serdes node in
      the device tree

v2 -> v3:
    - Sorted the Kconfig sourced folders
    - Sorted the Makefile included folders
    - Changed the configuration interface documentation to use kernel style

v1 -> v2: Fixed kernel test robot warnings
    - Made these structures static:
      - media_presets_25g
      - mode_presets_25g
      - media_presets_10g
      - mode_presets_10g
    - Removed these duplicate initializations:
      - sparx5_sd25g28_params.cfg_rx_reserve_15_8
      - sparx5_sd25g28_params.cfg_pi_en
      - sparx5_sd25g28_params.cfg_cdrck_en
      - sparx5_sd10g28_params.cfg_cdrck_en
