		7. Add a spin_lock for loongson_spi_setup.
		8. Add a timeout and cpu_relax() in loongson_spi_write_read_8bit.

		   that reported by test robot.
		6. Remove the spin lock.
		7. Clear the loongson_spi->hz and loongson_spi->mode in setup to fixup

		2. Add "#include <linux/io.h>" in spi-loongson-core.c for fix the compile
		   issue which devm_ioremap no declaration.
		3. Add "EXPORT_SYMBOL_GPL(loongson_spi_dev_pm_ops)" in
		   spi-loongson-core.c for fix the compile issue which
		   loongson_spi_dev_pm_ops undefined.
