Gunar Schorcht	26613ee9e7	cpu/esp32: SPI configuration approach changed ... SPI devices are now configured using static array in header files instead of static variables in implementation to be able to define SPI_NUMOF using the size of the array instead of a variable.	2019-05-06 13:33:48 +02:00
Gunar Schorcht	437f8b87b9	cpu/esp32: cleanup of SPI interfaces ... Although ESP32 has four SPI controllers, only two of them can be effectively used (HSP and VSPI). The third one (FSPI) is used for external memory such as flash and PSRAM and can not be used for peripherals. FSPI is therefore removed from the API. In addition, the SPI0_DEV and SPI1_DEV configuration parameters are renamed SPI0_CTRL and SPI1_CTRL to better describe what they define and to avoid confusion with SPI_DEV (0) and SPI_DEV (1).	2019-01-09 13:03:22 +01:00
