Subject: [PATCH v1 2/2] riscv: dts: starfive: visionfive 2: Add configuration of gmac and phy
Date: Fri, 14 Jul 2023 18:45:21 +0800 [thread overview]
Message-ID: <20230714104521.18751-3-samin.guo@starfivetech.com> (raw)
In-Reply-To: <20230714104521.18751-1-samin.guo@starfivetech.com>
v1.3B:
v1.3B uses motorcomm YT8531(rgmii-id phy) x2, need delay and
inverse configurations.
The tx_clk of v1.3B uses an external clock and needs to be
switched to an external clock source.
v1.2A:
v1.2A gmac0 uses motorcomm YT8531(rgmii-id) PHY, and needs delay
configurations.
v1.2A gmac1 uses motorcomm YT8512(rmii) PHY, and needs to
switch rx and rx to external clock sources.
