Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). 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.
