  1. * ZTE specific extensions to the Synopsys Designware Mobile Storage
  2. Host Controller
  3. The Synopsys designware mobile storage host controller is used to interface
  4. a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
  5. differences between the core Synopsys dw mshc controller properties described
  6. by synopsys-dw-mshc.txt and the properties used by the ZTE specific
  7. extensions to the Synopsys Designware Mobile Storage Host Controller.
  8. Required Properties:
  9. * compatible: should be
  10. - "zte,zx296718-dw-mshc": for ZX SoCs
