The status quo on i.MX6 is that if "over-current-active-high" is specified in the device tree this is configured as expected. If the property is missing polarity isn't changed and so the polarity is kept as setup by the bootloader. Reset default is active high, so active low can only be used with help by the bootloader. On i.MX7 it is similar, but there disabling of over current detection has a similar inconsistency. This patch introduces a new property that allows to explicitly configure for active low over current detection and consistently sets this up. In the absence of an explicit configuration the bit is kept as is. On i.MX7 over current detection is used unless disabled in the device tree.
