[PATCH v5 20/26] ARM: dts: am437x: Fix NAND device nodes

Roger Quadros rogerq at ti.com
Fri Feb 19 13:15:42 PST 2016


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.
