-* Rockchip specific extensions to the Synopsys Designware Mobile
- Storage Host Controller
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core Synopsys dw mshc controller properties described
-by synopsys-dw-mshc.txt and the properties used by the Rockchip specific
-extensions to the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-
-* compatible: should be
- - "rockchip,rk2928-dw-mshc": for Rockchip RK2928 and following,
- before RK3288
- - "rockchip,rk3288-dw-mshc": for Rockchip RK3288
- - "rockchip,rv1108-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RV1108
- - "rockchip,px30-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip PX30
- - "rockchip,rk3036-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3036
- - "rockchip,rk3228-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK322x
- - "rockchip,rk3328-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3328
- - "rockchip,rk3368-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3368
- - "rockchip,rk3399-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3399
-
-Optional Properties:
-* clocks: from common clock binding: if ciu-drive and ciu-sample are
- specified in clock-names, should contain handles to these clocks.
-
-* clock-names: Apart from the clock-names described in synopsys-dw-mshc.txt
- two more clocks "ciu-drive" and "ciu-sample" are supported. They are used
- to control the clock phases, "ciu-sample" is required for tuning high-
- speed modes.
-
-* rockchip,default-sample-phase: The default phase to set ciu-sample at
- probing, low speeds or in case where all phases work at tuning time.
- If not specified 0 deg will be used.
-
-* rockchip,desired-num-phases: The desired number of times that the host
- execute tuning when needed. If not specified, the host will do tuning
- for 360 times, namely tuning for each degree.
-
-Example:
-
- rkdwmmc0@12200000 {
- compatible = "rockchip,rk3288-dw-mshc";
- reg = <0x12200000 0x1000>;
- interrupts = <0 75 0>;
- #address-cells = <1>;
- #size-cells = <0>;
- };
