/*
* STM32 USB OTG FS Host Driver Support
*
* Pre-requisites
*
* CONFIG_USBHOST - Enable general USB host support
* CONFIG_STM32_OTGFS - Enable the STM32 USB OTG FS block
* CONFIG_STM32_SYSCFG - Needed
*
* Options:
*
* CONFIG_STM32_OTGFS_RXFIFO_SIZE - Size of the RX FIFO in 32-bit words.
* Default 128 (512 bytes)
* CONFIG_STM32_OTGFS_NPTXFIFO_SIZE - Size of the non-periodic Tx FIFO
* in 32-bit words. Default 96 (384 bytes)
* CONFIG_STM32_OTGFS_PTXFIFO_SIZE - Size of the periodic Tx FIFO in 32-bit
* words. Default 96 (384 bytes)
* CONFIG_STM32_OTGFS_SOFINTR - Enable SOF interrupts. Why would you ever
* want to do that?
* CONFIG_STM32_USBHOST_REGDEBUG - Enable very low-level register access
* debug. Depends on CONFIG_DEBUG.
