Some Pine64+ boards come with bad RTL8211E PHYs, which cannot work reliably
unless do some hack. According to Pine64 people, Realtek describes the hack
as totally disabling RX delay, and it's not documented at all.
This patchset introduces the workaround on Pine64+.
The first patch adds RGMII variants' support to the dwmac-sun8i driver.
The second patch renames some macros in RTL PHY driver, and the third
patch introduces the hack as the "RGMII-TXID" mode of the PHY.
The fourth patch enables the hack in the device tree.
