/*
 * USB Pin Configuration:
 *
 * This board is equipped with three USB connectors: Type-A (CN80), Mini-B
 * (CN79), and Micro-AB (CN33). The RZ/T2H SoC has a single USB channel, so
 * either the USB host interface or the USB function interface can be used,
 * but not both simultaneously when using the CN79 and CN80 connectors.
 *
 * By default, the Type-A (CN80) and Mini-B (CN79) connectors are enabled.
 * Configure the switches as follows:
 *   - P00_0 - P00_2 (control signals for USB power supply): SW1[5] = ON
 *   - USB_VBUSIN (used for USB function): SW7[7] = OFF; SW7[8] = ON
 *   - USB_VBUSEN (used for USB_HF_VBUSEN): SW7[9] = OFF; SW7[10] = ON
 *
 * To enable the Micro-AB (CN33) USB OTG connector, set the following macro
 * to 1 and configure the switches as follows:
 *   - P00_0 - P00_2 (control signals for USB power supply): SW1[5] = ON
 *   - USB_VBUSIN (used for USB OTG): SW7[7] = ON; SW7[8] = OFF
 *   - USB_VBUSEN (used for USB_OTG_VBUSEN): SW7[9] = ON; SW7[10] = OFF
