After updating kernel to any 6.x kernel intermittently the display does not work, it will illuminate but is solid white, if I downgrade back to 5.19 kernel then the display works fine.
I was able to resolve this issue by switching the interface type from spi to gpio_cs_spi and then defining the chip select pin using the --gpio-chip-select parameter.
