In order to automate this process synopsys-dw-mshc.txt has to be converted to yaml. In the new setup synopsys-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'.

The name of the child node - representing the slot is recommended to be slot@n where n is the unique number - of the slot connected to the controller. The following are optional properties - which can be included in the slot child node. - - * reg: specifies the physical slot number. The valid values of this - property is 0 to (num-slots -1), where num-slots is the value - specified by the num-slots property. - - * bus-width: as documented in mmc core bindings. - - * wp-gpios: specifies the write protect gpio line. The format of the - gpio specifier depends on the gpio controller. If a GPIO is not used - for write-protect, this property is optional. - - * disable-wp: If the wp-gpios property isn't present then (by default) - we'd assume that the write protect is hooked up directly to the - controller's special purpose write protect line (accessible via - the WRTPRT register).

If the - ciu clock is missing we'll just assume that the clock is running at - clock-frequency. It is an error to omit both the ciu clock and the - clock-frequency. - -* clock-frequency: should be the frequency (in Hz) of the ciu clock.
