Merge tag 'phy-for-4.9-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-linus
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
