Fix whitespace coding style: use single space instead of tabs or
multiple spaces around '=' sign in property assignment. No functional
changes (same DTB).

In accordance with the DWC USB3 bindings the corresponding node
name is suppose to comply with the Generic USB HCD DT schema, which
requires the USB nodes to have the name acceptable by the regexp:
"^usb(@.*)?" . Make sure the "snps,dwc3"-compatible nodes are correctly
named.

Syonpsys IP cores are supposed to be defined with "snps" vendor-prefix.
Use it instead of the deprecated "synopsys" one.

The device node name should reflect generic class of a device so rename
the "msmram" node and its children to "sram". This will be also in sync
with upcoming DT schema. No functional change.

The keystone_irq node describes a device that is a member of the device
state control module address space. As such, it should not be a member
of soc0 bus but instead a sub-node of device-state-control.
This move also fixes a warning about not having a reg property. Now
that this is a sub-node of device-state-control, a syscon type node,
we add this reg property but relative to the syscon base, this way
when the dt-binding/driver are updated we can drop the non-standard
gpio,syscon-dev property completely and simply use get_resource() in
the driver.

Provide a soc0 node and reference the same to simplify dts. This also
resolves the following warnings when built with W=1:
arch/arm/boot/dts/keystone-k2hk-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2l-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2e-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2g-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2g-ice.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
NOTE: Though we can reformat files by reducing 1 level of indent due to
the use of soc0 phandle, we omit that change to prevent un-necessary
churn in code base.

Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'
Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

The Keystone 2 66AK2E SoC has one TMS320C66x DSP Core Subsystem
(C66x CorePac), with a 1.4 GHz C66x Fixed or 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 processor does
not have a 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.

The Power Sleep Controller (PSC) module contains specific
memory-mapped registers that can be used to perform reset
management using specific bits for the DSPs available on the
SoC. The PSC is defined using a syscon node, and the reset
functionality is defined using a child syscon reset controller
node.
Add this syscon reset controller node as well as the reset
control data for the resets it supports for the 66AK2E SoCs.

The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c1f0000
on 66AK2E SoCs, so add a reserved child node for the same.
This address is aligned to the values used within the latest boot
monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load
address to end of MSMC").

Add the RAM managed by the Multicire Shared Memory Controller (MSMC)
as a mmio-sram node. The 66AK2E SoCs have 2 MB of such memory. Any
specific MSM memory range needed by a software module ought to be
reserved using an appropriate child node.

The USB OTG mode is not supported by Kestone 2 devices, as result, the
USB devices enumeration and detection will not work properly when
kernel is built with CONFIG_USB_DWC3_DUAL_ROLE=y (default for multi
platform build):
- it's required to load gadget drivers manually to make host mode
work and this confuses current Keystone 2 users
- device mode is not working, because port can't detect and switch to
peripheral/host mode dynamically.
Hence, specify usb mode explicitly in DT: usb0 = "host" for all KS2
devices and usb1 = "peripheral" for K2E.

The PCI DT bindings contain a bogus entry for IO space which is not
supported on Keystone. The current bogus entry has an invalid size
and throws following error during boot.
[0.420713] keystone-pcie 21021000.pcie: error -22: failed to map
resource [io 0x0000-0x400000003fff]
So remove it from the dts. While at it also add a bus-range
value that eliminates following log at boot up.
[0.420659] No bus range found for /soc/pcie@21020000, using [bus 00-ff]

As reported in [1], rename the k2* dts files to keystone-* files
this will force consistency throughout.
Script for the same (and hand modified for Makefile and MAINTAINERS
files):
for i in arch/arm/boot/dts/k2*
do
b=`basename $i`;
git mv $i arch/arm/boot/dts/keystone-$b;
sed -i -e "s/$b/keystone-$b/g" arch/arm/boot/dts/*[si]
done
NOTE: bootloaders that depend on older dtb names will need to be
updated as well.
