1 * Rockchip specific extensions to the Synopsys Designware Mobile
2 Storage Host Controller
4 The Synopsys designware mobile storage host controller is used to interface
5 a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
6 differences between the core Synopsys dw mshc controller properties described
7 by synopsys-dw-mshc.txt and the properties used by the Rockchip specific
8 extensions to the Synopsys Designware Mobile Storage Host Controller.
12 * compatible: should be
13 - "rockchip,rk2928-dw-mshc": for Rockchip RK2928 and following,
15 - "rockchip,rk3288-dw-mshc": for Rockchip RK3288
18 * clocks: from common clock binding: if ciu_drive and ciu_sample are
19 specified in clock-names, should contain handles to these clocks.
21 * clock-names: Apart from the clock-names described in synopsys-dw-mshc.txt
22 two more clocks "ciu-drive" and "ciu-sample" are supported. They are used
23 to control the clock phases, "ciu-sample" is required for tuning high-
26 * rockchip,default-sample-phase: The default phase to set ciu_sample at
27 probing, low speeds or in case where all phases work at tuning time.
28 If not specified 0 deg will be used.
