Some PHY controllers may need to calibrate certain PHY settings after initialization of the controller and sometimes even after initializing the PHY-consumer too. Add support for the same in order to let consumers do so in need. Signed-off-by: vivek Gautam gautam.vi...@samsung.com --- drivers

Re: [PATCH 2/4] usb: host: xhci-plat: Add support to get PHYs

host controllers already conveniently have two struct usb_hcd (one for 2.0 and one for 3.0), you can cleanly store references to your two PHYs in there. Ok, i will look into the suggested approach, and raise flag in case i have doubts. -- Best Regards Vivek Gautam Samsung RD Institute
