[next 0/5] Add support of Ethernet for Aspeed AST2600 SoC

[next 0/5] Add support of Ethernet for Aspeed AST2600 SoC

[Dylan Hung]

This patch series adds support of Ethernet for Aspeed AST2600 SoC. There
are 4 MAC controllers (ftgmac100) in AST2600 that can support
10/100/1000T Ethernet.  4 MDIO controllers are used to connect to PHY
chips.  The MDIO controller has stand-alone hardware block so we
introduce DM_MDIO so that we can use external MDIO driver (aspeed_mdio)
instead of integrated MDIO drier in ftgmac100.c.  The patch series also
revises the MII interface delay for better RMII/RGMII timing margin.

[next 1/5] net: ftgmac100: Add DM_MDIO support

[Dylan Hung]

Add support for DM_MDIO to connect to PHY.  For the systems that have a
stand-alone MDIO hardware block, enable CONFIG_DM_MDIO to use driver
model for MDIO devices.

[next 2/5] net: ftgmac100: Add Aspeed AST2600 support

[Dylan Hung]

Add support of the MAC controller of Aspeed AST2600 SOC.  The MAC
controller is the same with AST2500, except it has stand-alone MDIO
hardware block.

[next 3/5] ARM: dts: ast2600: Add MDIO devices

[Dylan Hung]

There are 4 MDIO bus controllers in AST2600 SOC.  Each of them can
connect to one or more PHY chips and is flexible to work with the 4 MAC
devices in AST2600.  On AST2600 EVB, MDIO 0,1,2,3 connect to the PHY
chips used by MAC 0,1,2,3 respectively.

[next 5/5] clk: ast2600: Revise MII interface delay

[Dylan Hung]

The clock delay of the RMII/RGMII interface is controlled by SCU340~35C.
These values are obtained by measurement and experiments so we simply
use macro to define them.
