I see. Thanks for reminding.
Hi Vinod,
Could you please help to apply below two patches:
- [v4 1/2] dt-bindings: phy: mxs-usb-phy: convert to DT schema format
- [v4,2/2] dt-bindings: phy: mxs-usb-phy: add imx8ulp and imx8qm compatible
The review process has been completed.
Many thanks in advance.
Thanks,
Xu Yang
