@@ -21,6 +21,11 @@ Optional properties:
below for the case, when a GPIO is used for the CD line
- wp-inverted: when present, polarity on the WP line is inverted. See the note
below for the case, when a GPIO is used for the WP line
+- disable-wp: When set no physical WP line is present. This property should
+ only be specified when the controller has a dedicated write-protect
+ detection logic. If a GPIO is always used for the write-protect detection
+ logic it is sufficient to not specify wp-gpios property in the absence of a WP
+ line.
- max-frequency: maximum operating clock frequency
- no-1-8-v: when present, denotes that 1.8v card voltage is not supported on
this system, even if the controller claims it is.
