Fallback to something like apple,t8103-spi instead. Have you looked at it? This one still seems to be somehow Samsung related. See the previous discussion at https://lore.kernel.org/linux-devicetree/d87ae109-4b58-7465-b16e-3bf7c9d60f1f@marcan.st/ Even the A7-A11 SPI controllers are not compatible "apple,spi" doesn't prevent us from using something like "apple,s5l-spi" for those.
