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

Now that PCIe DT binding is disabled in SoC specific DTS,

Currently PCIe DT bindings are broken. PCIe driver can't function
without having a SerDes driver that provide the phy configuration.
On K2E EVM, this causes problem since the EVM has Marvell SATA
controller present and with default values in the SerDes register,
it seems to pass the PCIe link check, but causes issues since
the configuration is not correct. The manifestation is that when
EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable
PCIe on this EVM since to work, SerDes driver has to be present as
well. So by default, the PCIe DT binding should be disabled in SoC
specific DTS. It can be enabled in the board specific DTS when the
SerDes device driver is also present.
So fix the status of PCIe DT bindings in the SoC specific DTS to
"disabled". To enable PCIe, the status should be set to "ok" in
the EVM DTS file when SerDes driver support becomes available in
the upstream tree.

This is a small follow-up to the larger ARM SoC updates merged
last week, almost entirely for the keystone platform.
The main change here is to use the new dma-ranges parsing code
that came in through Russell's ARM tree. This allows the keystone
platform to do cache-coherent DMA and to finally support all the
available physical memory when LPAE is enabled.
Aside from this, the keystone reset driver has been rewritten,
and there is a small bug fix to allow building the orion5x platform
again.

The pll controller register set and device state control registers
include sets of registers with different purposes, so it's logically
to add syscon entry to be able to access them from appropriate places.
So added pll controller and device state control syscon entries.
The keystone driver requires the next additional properties:
"ti,syscon-pll" - phandle/offset pair. The phandle to syscon used to
access pll controller registers and the offset to use
reset control registers.
"ti,syscon-dev" - phandle/offset pair. The phandle to syscon used to
access device state control registers and the offset
in order to use mux block registers for all watchdogs.
"ti,wdt-list" - option to declare what watchdogs are used to reboot
the SoC, so set "0" WDT as default.
