v2->v3:
1.Add "ingenic,mac.yaml" for Ingenic SoCs.
2.Change tx clk delay and rx clk delay from hardware value to ps.
3.return -EINVAL when a unsupported value is encountered when
parsing the binding.
4.Simplify the code of the RGMII part of X2000 SoC according to
Andrew Lunn’s suggestion.
5.Follow the example of "dwmac-mediatek.c" to improve the code
that handles delays according to Andrew Lunn’s suggestion.

2.7.4
Add support for Ingenic SoC MAC glue layer support for the stmmac
device driver. This driver is used on for the MAC ethernet controller
found in the JZ4775 SoC, the X1000 SoC, the X1600 SoC, the X1830 SoC,
and the X2000 SoC.

Notes:
v1->v2:
1.Fix uninitialized variable.
2.Add missing RGMII-ID, RGMII-RXID, and RGMII-TXID.
3.Change variable val from int to unsinged int.
4.Get tx clock delay and rx clock delay from devicetree.
v2->v3:
1.Change tx clk delay and rx clk delay from hardware value to ps.
2.return -EINVAL when a unsupported value is encountered when
parsing the binding.
3.Simplify the code of the RGMII part of X2000 SoC according to

Perhaps 3 hours is not sufficient time to review. It may be a v3, but
the binding appears to have changed quite a bit in addition to being
broken.

Sorry for that, somehow when I run "make dt_bindings_check", there is no
warrning or error message about this file. I am sure that yamllint is
installed and dtschema has been upgraded to 2021.6.
I will send a fix.

I found that it seems to be because 5.13 newly introduced
"DT_CHECKER_FLAGS=-m", and I am still using the old
"make dt_binding_check" command, so this error is not prompted. Now I
can see this error message after using the
"make DT_CHECKER_FLAGS=-m dt_binding_check" command, and I will send a
fix soon.
