I need to implement SPI Slave driver on 4020 chipset. So 4020 chipset needs to act as an SPI Slave. Check QAPI and found that only SPI master APIs are available, nothing for SPI Slave. Can you point me to API or SPI Slave example code for QCA4020 chipset?

Kindly refer to "HTC Slave" demo which uses SDIO/SPI for conection between two QCA4020 devices which acts as master/ slave configuration.
