Date: Tue, 13 May 2026 00:00:00 +0800
Subject: [PATCH] rk3588s: orangepi-cm5: gmac1 RMII for YT8522C on custom board
Configure GMAC1 for RMII mode with Motorcomm YT8522C PHY:
- Switch from RGMII to RMII mode
- SOC outputs 25MHz refclk (REFCLKO25M_ETH1_OUT) to PHY via GMAC_MCLK pin
- PHY address: 0x1 (PHYAD[1:0] = 2'b01 per schematic)
- PHY reset: GPIO1_C1 (active-low, per MR3588S_MB_BASE_V1.0 schematic)
- Remove RGMII-specific pinmux, tx/rx delay settings
- Add RMII clock pinmux (gmac1_clkinout)
