Subject: [PATCH 1/1] ARM: dts: stm32: replace rgmii mode with rgmii-id on stm32mp15 boards
Date: Mon, 17 Jun 2019 10:50:18 +0200 [thread overview]
Message-ID: <20190617085018.20352-2-christophe.roullier@st.com> (raw)
In-Reply-To: <20190617085018.20352-1-christophe.roullier@st.com>
On disco and eval board, Tx and Rx delay are applied (pull-up of 4.7k
put on VDD) so which correspond to RGMII-ID mode with internal RX and TX
delays provided by the PHY, the MAC should not add the RX or TX delays
in this case
