The Keystone 2 66AK2G SoC has a single TMS320C66x DSP Core
Subsystem (C66x CorePac), containing a C66x Fixed/Floating-Point
DSP Core, and 32 KB of L1P & L1D SRAMs and a 1 MB L2 SRAM. Add
the DT node for this DSP processor sub-system.
The DT node has a new property 'power-domains' and no 'clocks'
properties, and uses slightly different property values for
'resets' compared to other Keystone 2 SoCs. The processor does
not have an MMU, and uses various IPC Generation registers and
shared memory for inter-processor communication. The alias with
a stem 'rproc' has also been added for the DSP, it provides a
fixed remoteproc id for the DSP processor.

[s-anna@ti.com: add unit address to DT node]

Adding the unit address to the memory node was causing the below error:
Warning (reg_format): "reg" property in /memory has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 2)
Further debugging showed that this was due to the memory node added by
default to skeleton.dtsi which was being included in keystone-k2g.dtsi.
Adding a missing node was all that was needed to remove this deprecated
dtsi file from the SoC dtsi. With skeleton.dtsi removed the dtc compiler
no longer complained about including the unit address for the memory node.

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.
Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).
In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c0f7000

This address is aligned to the values used within the latest boot
monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load

The TI Keystone SoCs have extra UART registers beyond the standard 8250
registers, so we need a new compatible string to indicate this. Also, at
least one of these registers uses the full 32 bits, so we need to specify
reg-io-width in addition to reg-shift.
"ns16550a" is left in the compatible specification since it does work as
long as the bootloader configures the SoC UART power management registers.

K2G is the newest addition of TI's Keystone 2 product family. It is a
single core Cortex A15 and a C66x DSP.
K2G supports standard peripherals such as SPI, UART, MMC and USB 2.0.
Includes two dual-core Programmable Real-time Unit and Industrial
Communication Subsystems (PRU-ICSS).
The technical reference manual for K2G can be found here:
http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf
This device is targeted for a variety of applications which include, but
are not limited to:
Home audio
Professional audio
Industrial Programmable Logic Control
The peripheral nodes that have been included in this patch have been
tested during bring-up. Since all peripherals will not necessarily be
used on all boards, disable all peripherals by default. This allow
the board dts to selectively choose which peripherals it wants to
enable.
This SoC now uses the next generation of power management architecture
with the PM functionality located in a microcontroller embedded in the SOC.
Support for this new PM architecture along with other peripherals will be
added in future patches.
