Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

ST USB OHCI controller
|
|
|
|
Required properties:
|
|
|
|
- compatible : must be "st,st-ohci-300x"
|
|
- reg : physical base addresses of the controller and length of memory mapped
|
|
region
|
|
- interrupts : one OHCI controller interrupt should be described here
|
|
- clocks : phandle list of usb clocks
|
|
- clock-names : should be "ic" for interconnect clock and "clk48"
|
|
See: Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
- phys : phandle for the PHY device
|
|
- phy-names : should be "usb"
|
|
|
|
- resets : phandle to the powerdown and reset controller for the USB IP
|
|
- reset-names : should be "power" and "softreset".
