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.

Without this patch:
git grep -wn "cmd-gpios"
