Subject: [PATCH 1/2] dt-bindings: net: dwmac-meson: Add a compatible string for G12A onwards
Date: Sat, 20 Jun 2020 21:26:40 +0200 [thread overview]
Message-ID: <20200620192641.175754-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20200620192641.175754-1-martin.blumenstingl@googlemail.com>
Amlogic Meson G12A, G12B and SM1 have the same (at least as far as we
know at the time of writing) PRG_ETHERNET glue register implementation.
This implementation however is slightly different from AXG as it now has
an undocument "auto cali idx val" register in PRG_ETH1[17:16] which
seems to be related to RGMII Ethernet.
Add a compatible string for G12A and newer so the new registers can be
used.
