* 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
