No > 32bit NXP SoC uses this particular display controller. So, that should > fix the compilation issue on 32bit. Build coverage for ARM64 is an OK short term fix. Please fix the driver so we can build test it for all architectures. The chance to miss something when refactoring if only build for ARM64 is too high. The fix can land when it is ready, and is not urgent. Sam
