This patch adds support to set the power line polarity for i.MX SoCs. To let the USB controller control the power it may be necessary to configure the polarity of the power line. So far the polarity was configured by Bootloader or alternatively the power line was muxed as gpio and driven by a regulator. Also make use of of_property_read_bool.
