Subject: [RFC][BUG] arm/dts: OMAP3: set #interrupt-cells to two
Message-ID: <1364631689.3767.7.camel@mars>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

This patch sets gpio #interrupt-cells from a falsely acquired '1' to '2'
referring to Documentation/devicetree/bindings/gpio/gpio-omap.txt:

      The first cell is the GPIO number.
      The second cell is used to specify flags:
        bits[3:0] trigger type and level flags:
          1 = low-to-high edge triggered.
          2 = high-to-low edge triggered.
          4 = active high level-sensitive.
          8 = active low level-sensitive.

But using this trigger cell in a board specific devicetree leads to a
non-starting kernel. This is due to not yet enabled gpio-clocks while
kernel/irq/irqdomain.c tries to set this trigger-flag (from the second
interrupt-cell) to gpio-irq-controller.

 Any ideas?
