Add initial support for ethernet controller of the Spacemit K3 SoC.
This ethernet controller is almost a standard Synopsys DesignWare
MAC (version 5.40a). This controller require a syscon device to
configure some basic features, like interface type and internal delay.
Change from v3:
- https://lore.kernel.org/netdev/20260128072931.875041-1-in...
patch 1:
1. fix the uncorrect compatible string postion
patch 3:
1. add "CTRL_" prefix to all ctrl register definition
2. only use delay config 0 to calculate delay code.
3. fix typo in the comment
Change from v2:
- https://lore.kernel.org/netdev/20260121071315.940130-1-in...
patch 1:
1. remove not needed compatible for select
2. drop empty line in "spacemit,apmu" properties
3. add spacemit,apmu properties to required.
patch 3:
1. remove misused phy_fix_phy_mode_for_mac_delays.
2. use local tx clock instead of the clk_tx_i in the dwmac.
Change from v1:
- https://lore.kernel.org/netdev/20260120043609.910302-1-in...
patch 1:
1. remove phy clock
patch 3:
1. improve comment and include something special about Spacmit K3 dwmac
2. reorder the included file
3. fix wrong delay macro used in spacemit_dwmac_set_delay.
4. add check for maximum supported delay.
5. use DIV_ROUND_CLOSEST to calculate best delay configuration.
6. use assign for the ctrl register initial value.
7. fix input when calling of_property_read_u32().
