Subject: [PATCH] arm64: dts: allwinner: a64-sopine-baseboard: change RGMII mode to TXID
Date: Wed,  9 Jun 2021 16:38:43 +0800
Message-ID: <> (raw)

Although the schematics of Pine A64-LTS and SoPine Baseboard shows both
the RX and TX internal delay are enabled, they're using the same broken
RTL8211E chip batch with Pine A64+, so they should use TXID instead, not

In addition, by checking the real components soldered on both a SoPine
Baseboard and a Pine A64-LTS, RX delay is not enabled (GR69 soldered and
GR70 NC) despite the schematics says it's enabled. It's a common
situation for Pine64 boards that the NC information on schematics is not
the same with the board.

So the RGMII delay mode should be TXID on these boards.
