Merge tag 'spi-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "A quiet release for SPI, not even many driver updates:

   - Add a dummy loopback driver for use in exercising framework
     features during development.

   - Move the test utilities to tools/ and add support for transferring
     data to and from a file instead of stdin and stdout to spidev_test.

   - Support for Mediatek MT2701 and Renesas AG5 deices"
