Silicon limitation i845 documents how to cope with false
disconnection condition on USB2 PHY. Reference: AM572x
silicon errata document SPRZ429H, revised January 2016.

Using compatible "ti,dra7x-usb2" enables the recommended
software workaround for this issue. Use it for USB1 PHY.

The workaround is already in place for USB2 PHY.

The wega board has a TLV320AIC3007 connected via McASP0. In the default
configuration, no external crystal is mounted. We run a system clock of
25 MHz, so we use the audio codec PLL for audio clock generation.

AM572x IDK has a Spansion s25fl256s1 QSPI flash on the EVM connected to
TI QSPI IP over CS0. Hence, add QSPI and flash slave DT nodes.

According to AM572x DM SPRS953A, QSPI maximum bus speed can be 76.8MHz.
Therefore, increase the spi-max-frequency value of QSPI node to 76.8MHz
for DRA74 and DRA72 evm. This improves flash raw read speed by ~2MB/s.

Without this, the memory will remain active during poweroff consuming

disable is attempted, so this is not done on that PMIC revision. The
PMIC revision checks in the regulator patches make sure of this.

Commit b8d368ca ("ARM: dts: omap3: overo: remove unneded unit names
in display nodes") removed the unit names for all Overo display nodes
that didn't have a reg property.

But the display in arch/arm/boot/dts/omap3-overo-common-lcd35.dtsi does
have a reg property so the correct fix was to make the unit name match
the value of the reg property, instead of removing it.

This patch fixes the following DTC warning for boards using this dtsi:

"ocp/spi@48098000/display has a reg or ranges property, but no unit name"

The gpmc ranges property for NAND at CS0 was being overridden by later
includes that defined gpmc ethernet nodes, effectively breaking NAND on
these systems:

	omap-gpmc 6e000000.gpmc: /ocp/gpmc@6e000000/nand@0,0 has
	malformed 'reg' property

Instead of redefining the NAND range in every such dtsi, define all
currently used ranges in omap3-overo-base.dtsi.

The gpmc ranges property for NAND at CS0 has been broken since it was
first added.

This currently prevents the nand gpmc child node from being probed:

	omap-gpmc 6e000000.gpmc: /ocp/gpmc@6e000000/nand@0,0 has
	malformed 'reg' property

and consequently the NAND device from being registered.

Having those command and corresponding PSCI support in boot monitor
allows run time CPU hot plugin.
