0001 * Hisilicon specific extensions to the Synopsys Designware Mobile
0002 Storage Host Controller
0003
0004 Read synopsys-dw-mshc.txt for more details
0005
0006 The Synopsys designware mobile storage host controller is used to interface
0007 a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
0008 differences between the core Synopsys dw mshc controller properties described
0009 by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific
0010 extensions to the Synopsys Designware Mobile Storage Host Controller.
0011
0012 Required Properties:
0013
0014 * compatible: should be one of the following.
0015 - "hisilicon,hi3660-dw-mshc": for controllers with hi3660 specific extensions.
0016 - "hisilicon,hi3670-dw-mshc", "hisilicon,hi3660-dw-mshc": for controllers
0017 with hi3670 specific extensions.
0018 - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extensions.
0019 - "hisilicon,hi6220-dw-mshc": for controllers with hi6220 specific extensions.
0020
0021 Optional Properties:
0022 - hisilicon,peripheral-syscon: phandle of syscon used to control peripheral.
