This is a note to let you know that I've just added the patch titled
dt-bindings: phy: qcom,qmp-usb3-dp: Add DP phy information
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-next branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: dt-bindings: phy: qcom,qmp-usb3-dp: Add DP phy information
This binding only describes the USB phy inside the USB3 + DP "combo"
phy. Add information for the DP phy and describe the sub-nodes that
represent the DP and USB3 phys that exist inside the combo wrapper.
Remove reg-names from required properties because it isn't required nor
used by the kernel driver.
