Peter writes:

Hi Greg,

In this series, it adds qualcomm USB2 support. The review process takes
more than half of year, thanks for Stephen Boyd's great work.

Most of patches at linux-next more than ten days, and the last two small
chipidea patches at my tree about one day, no warning is reported from
autobuild robot.

Thanks.

ULPI bus binding

----------------



Phys that are behind a ULPI connection can be described with the following

binding. The host controller shall have a "ulpi" named node as a child, and

that node shall have one enabled node underneath it representing the ulpi

device on the bus.



EXAMPLE

-------



usb {

	compatible = "vendor,usb-controller";



	ulpi {

		phy {

			compatible = "vendor,phy";

		};

	};

};
