Making strange changes to #BL602 #NuttX SPI Driver ... Hope this works for ST7789 Display 🙏
https://github.com/lupyuen/incubator-nuttx/blob/st7789/arch/risc-v/src/bl602/bl602_spi.c#L678-L729
After every ST7789 SPI Transfer on #BL602 #NuttX, we revert MISO from GPIO Pin back to SPI Pin ... In case other drivers need MISO

Tested the ST7789 Data / Command Pin with a Logic Analyser ... Yep it works on #BL602 #NuttX! 🎉
