The module has the RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531 PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin header. The YT8531 has no crystal, so it uses the SoC 25 MHz reference output, described on the gmac node as clk_mac_refout. Its reset is described at the MDIO bus level: mdiobus releases a bus level reset before it scans for PHY IDs, whereas a per-PHY reset-gpios is only applied once the PHY has been found, which never happens while the PHY is still in reset.
