     55SPI is brought out on most Venice SBCs. Please refer to the hardware manual for pin outs.
     56
     57Gateworks uses the eCSPI modules of the i.mx8 for external connections. The FlexSPI or QSPI is not used, as this is typically used for flash devices, etc.
     58
     59eCSPI{1,2,3} supports data rate up to 52Mbits/s and SPI is a 1bit bus, thus the max bus speed is 52MHz.
     60
     61Typical pins exposed are:
     62- MOSI
     63- MISO
     64- SCLK (Up to 52MHz clock supported)
     65- SS0# (This is chip select 0)
