3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nishanth Menon <nm@ti.com>
commit e49d519c456f4fb6f4a0473bc04ba30bb805fce5 upstream.
GPIO modules are also interrupt sources. However, they require both the GPIO number and IRQ type to function properly.
By declaring that GPIO uses interrupt-cells=<1>, we essentially do not allow users of the nodes to use the interrupt property appropritely.
With this change, the following now works:
interrupt-parent = <&gpio6>; interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
