For SOMs with an onboard PHY, the PHY on the cartrier board is not used, and GPIO1_IO9 is used as a reset line to the onboard PHY. For SOMs without an onboard PHY, the PHY on the carrier board is used. For this configuration, pca9534 GPIO 5 (located on the carrier board) is used as a reset line to the PHY, and GPIO1_IO9 is not used. GPIO1_IO9 is not connected to any user-accessible pins or functions, and leaving it enabled in the mux pinctrl for both configurations is safe.
