		2. Remove the clock-names in spi yaml file.
		3. Add "loongson,ls7a-spi" compatible in spi yaml file.
		4. Add an || COMPILE_TEST and drop && PCI then add some CONFIG_PCI
		   macro to limit some pci code.
		5. Make the spi driver top code comment block that use C++ style.
		6. Drop spi->max_speed_hz.
		7. Add a spin_lock for loongson_spi_setup.
		8. Add a timeout and cpu_relax() in loongson_spi_write_read_8bit.
		9. Add spi_transfer_one and drop transfer and rework entire spi
		   driver that include some necessary changes.
