Subject[PATCH 1/2] devicetree: mxsfb: add reset-active property
Date
Some boards connect the LCD_RESET pin to a reset input on the
display panel. On these boards, this pin must be set to the
proper level for the display to function.

This adds an optional "reset-active" property to the "display"
subnode such that devicetrees can specify the desired polarity
of the LCD_RESET pin.
