Kishon writes:

phy: for 4.9 -rc

phy fixes:
*) Add a empty function for phy_reset when CONFIG_GENERIC_PHY is not set
*) change the phy lookup table for da8xx-usb to match it with the name
   present in the board configuraion file (used for non-dt boot)
*) Fix incorrect programming sequence in w.r.t deassert of phy_rst
   in phy-rockchip-pcie
*) Fix to avoid NULL pointer dereferencing error in sun4i phy
