From mboxrd@z Thu Jan 1 00:00:00 1970 From: martin.blumenstingl@googlemail.com (Martin Blumenstingl) Date: Wed, 2 May 2018 00:00:45 +0200 Subject: [PATCH 1/1] ARM: dts: meson8b: RGMII doesn't use the eth_txd1_1 and eth_txd0_1 pins In-Reply-To: <20180501220045.2004-1-martin.blumenstingl@googlemail.com> References: <20180501220045.2004-1-martin.blumenstingl@googlemail.com> Message-ID: <20180501220045.2004-2-martin.blumenstingl@googlemail.com> To: linus-amlogic@lists.infradead.org List-Id: linus-amlogic.lists.infradead.org The pin groups eth_txd0_0 and eth_txd0_1 are both connected to the Ethernet controller's TXD0 data line. The only difference is that eth_txd0_0 is routed to GPIOH_6 while eth_txd0_1 is routed to DIF_2_P. eth_txd1_0 and eth_txd1_1 are similar: eth_txd1_0 is routed to GPIOH_5 and eth_txd1_1 is routed to DIF_2_N. The schematics of the Odroid-C1+ show that it uses GPIOH_5 and GPIOH_6 for the TXD0 and TXD1 data lines. Thus we can drop eth_txd0_1 and eth_txd1_1 (which are routed to DIF_2_P and DIF_2_N) from the RGMII group.
