99663d4ef3 ARM: dts: keystone-k2l-evm: Add and enable common DSP CMA memory pool
A common CMA memory pool reserved memory node is added, and is attached
to all the DSP nodes through the 'memory-region' property on the 66AK2L
EVM board. This area will be used for allocating virtio rings and buffers.
The common node allows the DSP Memory Protection and Address Extension
(MPAX) module to be configured uniformly across all the DSP processors.

The reserved memory node and all the user DSP nodes are also marked okay
to enable the DSPs on the 66AK2L EVM board.

644978440c ARM: dts: keystone: specify usb mode explicitly
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.

5edafc2982 ARM: dts: k2*: Rename the k2* files to keystone-k2* files
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.
