Hi everyone,

I need to connect a SPI TFT display using fbtft driver on RK3328-SOM-EVB.

I made some DTS changes in order to enable SPI_CSN1_M0 and spidev.

I made a SPI example for spidev and SPI signals are ok but no cs toggling happens.

I have a big doubt if this pin could be a CS for that SPI: MISO, MOSI and CLOCK are referred to a M2 mux but SPI_CSN1_M0 are referred to M0 mux.

There is someone that had luck with this SPI?

Thanks.
