title: Serial NOR flash controller for MediaTek ARM SoCs

description: |
  This spi controller support single, dual, or quad mode transfer for
  SPI NOR flash. There should be only one spi slave device following
  generic spi bindings. It's not recommended to use this controller
  for devices other than SPI NOR flash due to limited transfer
  capability of this controller.
