dt-bindings: mmc: convert rockchip dw-mshc bindings to yaml
Current dts files with 'dwmmc' nodes are manually verified. In order to automate this process rockchip-dw-mshc.txt has to be converted to yaml. In the new setup rockchip-dw-mshc.yaml will inherit properties from mmc-controller.yaml and synopsys-dw-mshc-common.yaml. 'dwmmc' will no longer be a valid name for a node and should be changed to 'mmc'.

* 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>;
|
||||
