And in addition to specifying the wrong GPIO for controling the power of one of the mini-PCIe, I recently discovered that the power of both slots can be controlled. This patch specifies the correct GPIO for the left-most mini-PCIe slot of the D240 (labeled power_mpcie2 since the slot is attached to SIM2), and adds a GPIO that can be used to control the power of the other mini-PCIe slot (labeled power_mpcie1).
