[PATCH 1/3] ARM: dts: keystone-k2g: Add device state controller node

[Andrew F. Davis]

Add the device state controller node as a syscon node to the
Keystone 2 Galileo SoC. This module provides similar device
control functionality as that on the existing K2 SoCs.

One example usage would be the boot address programming of the
DSP processor sub-system.

[PATCH 2/3] ARM: dts: keystone-k2g: Add keystone IRQ controller node

[Andrew F. Davis]

Add the Keystone IRQ controller IP node on Keystone 2 Galileo
SoC. This allows the ARM CorePac core to receive interrupts
from remote processor devices (eg: DSP) on the SoC.

The IP is identical in functionality to that of the equivalent
nodes on existing K2 SoCs. The only difference is the ARM INTC
interrupt id/event number.

[PATCH 3/3] ARM: dts: keystone-k2g: Add DSP GPIO controller node

[Andrew F. Davis]

Add the DSP GPIO controller node on Keystone 2 Galileo SoC.
This is used to send interrupts to the only DSP processor
subsystem present on the SoC. The IP is identical to that
of the equivalent nodes on existing K2 SoCs.
