Esp32s3 QSPI support

[maro48m]

Hi,

I have JC3636W518EN, which is build of ESP32s3 with ST77916 display and CST816 touch.
According to specification display can be connected with QSPI and SPI
I've been able to draw "HELLO WORLD" on this display in ESP-IDF with QSPI connection, but not with SPI,
I've checked board and connection schematics and there is no SPI_DC pin assigned. I've contacted with shop i bought this doard, and they confirmed that no SPI connection is available.
So long story short - i've wanted to try and port esp-idf driver for that display, but can i create SPI.Bus for QSPI without DC pin?

Best regards,

pass -1 for the DC pin.
