| |
Add device tree binding for the BCM6345 soft reset controller.
The BCM6345 contains a soft-reset controller activated by setting a bit (that must previously have been cleared).
Signed-off-by: Simon Arlott <simon@fire.lp0.eu> --- v3: Resend. Example has changed because usbh now has two compatible strings and uses a power domain instead of a regulator.
v2: Renamed to bcm6345, removed "mask" property. Acked-by: Rob Herring <robh@kernel.org>
