+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 mmc properties described by mmc.txt and the
-properties used by the Synopsis Designware Mobile Storage Host Controller.
+properties used by the Synopsys Designware Mobile Storage Host Controller.
Required Properties:
* compatible: should be
- - snps,dw-mshc: for controllers compliant with synopsis dw-mshc.
+ - snps,dw-mshc: for controllers compliant with synopsys dw-mshc.
* #address-cells: should be 1.
* #size-cells: should be 0.
is specified and the ciu clock is specified then we'll try to set the ciu
clock to this at probe time.
+ * clock-freq-min-max: Minimum and Maximum clock frequency for card output
+ clock(cclk_out). If it's not specified, max is 200MHZ and min is 400KHz by default.
+
* num-slots: specifies the number of slots supported by the controller.
The number of physical slots actually used could be equal or less than the
value specified by num-slots. If this property is not specified, the value
* supports-highspeed: Enables support for high speed cards (up to 50MHz)
+ * caps2-mmc-hs200-1_8v: Supports mmc HS200 SDR 1.8V mode
+
+ * caps2-mmc-hs200-1_2v: Supports mmc HS200 SDR 1.2V mode
+
* broken-cd: as documented in mmc core bindings.
* vmmc-supply: The phandle to the regulator to use for vmmc. If this is
