[PATCH v3 22/27] ARM: dts: am437x: Fix NAND device nodes

Roger Quadros rogerq at ti.com
Fri Sep 18 07:53:44 PDT 2015


Add compatible id, GPMC register resource and interrupt
resource to NAND controller nodes.

The GPMC driver now implements gpiochip and irqchip so
enable gpio-controller and interrupt-controller properties.

With this the interrupt parent of NAND node changes so fix it
accordingly.
