[PATCH 0/2] ARM: dts: keystone-k2g: Fix usb-nop-xceiv dtbs_check warnings

[Bhargav Joshi]

usb0_phy and usb1_phy fail dtbs_check because:
- missing the required #phy-cells.
- simple-bus wrapper that forces unnecessary reg.

Patch 1 adds #phy-cells with value 0 as required by binding.
Patch 2 drops the wrapper and moves the PHYs to root.

[PATCH 1/2] ARM: dts: keystone-k2g: Add required #phy-cells to usb-nop-xceiv nodes

[Bhargav Joshi]

The usb-nop-xceiv binding requires "#phy-cells" with a value of 0.
usb0_phy and usb1_phy are missing it. Add the required property.

[PATCH 2/2] ARM: dts: keystone-k2g: Move usb-phy nodes out of simple-bus

[Bhargav Joshi]

usb0_phy and usb1_phy are usb-nop-xceiv NOP PHYs with no registers. They
sit under a usbphy simple-bus wrapper with unit-address names, which
forces a meaningless reg.

Drop the wrapper, reg and unit-addresses, move the PHYs to root with
plain unique names to fix dtbs_check errors.
