      ARM: dts: ux500: configure the accelerometers open drain · 7ba5dd53
      Linus Walleij authored
      
      
      Configure the two accelerometers sharing GPIO line 82 as:
      
      - Open drain so that they can share the same interrupt line.
      
      Configure the corresponding interrupt pin:
      
      - Trigger on the falling edge since open drain implies that we
        do not actively drive the line high, but we will actively drive
        it low to generate interrupts and then it moves from high to low
        i.e. a falling edge.
      
      - Pulled up so the line will be biased to high unless an IRQ
        is active on any device on the line, and thus it goes high
        again after the interrupt is deasserted.
