[PATCH v2 0/3] Add DSP control nodes for K2G

[Andrew F. Davis]

Hello all,

This series adds the nodes needed to control the DSP available on
this SoC. These are similar to the nodes already present the
other K2x SoCs.

Thanks,
Andrew

[PATCH v2 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
K2G 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 v2 2/3] ARM: dts: keystone-k2g: Add keystone IRQ controller node

[Andrew F. Davis]

Add the Keystone IRQ controller IP node on K2G 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 v2 3/3] ARM: dts: keystone-k2g: Add DSP GPIO controller node

[Andrew F. Davis]

Add the DSP GPIO controller node on K2G 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.

The series looks good to me. I will add them to the next merge
window queue...
