But Rob H accept or reject Look at the search result below. It seems that the driver have not been merged into mainline. But the property name is really used as cmd-gpio at mmp2-olpc-xo-1-75.dts:235, I don't think the mmp2-olpc-xo-1-75.dts can make a mistake. Otherwise, the driver will not work properly. Meanwhile, Both names cmd-gpios and cmd-gpio seem to be in use. But I prefer cmd-gpio, after all, only one gpio is assigned now. The motorola,cmd-gpios add "s" because it contains 3 gpio.
