Merge tag 'for-4.0-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-linus

Kishon writes:

contains fixes all over drivers/phy and includes the following
*) Using phy_get_drvdata instead of dev_get_drvdata in armada375-usb2.c
*) Fixes w.r.t checking return values in regmap APIs, protecting regmap ops
   with spin lock and directly using regmap_update_bits instead of having a
   separate function to do the same in the various PHYs used in exynos.
*) check return value in platform_get_resource of hix5hd2-sata PHY
*) Removed NULL terminating entry from phys array and fix off-by-one
   valid value checking for args->args[0] in of_xlate of exynos USB PHY.
*) Fixup rockchip_usb_phy_power_on failure path
*) Fix devm_phy_match to find the correct match in phy core and also fix to
   return the correct value from PHY APIs if PM runtime is not enabled.
*) Removed redundant code in twl4030 and xgene
*) Fixed sizeof during memory allocation in miphy PHYs
*) simplify ti_pipe3_dpll_wait_lock implementation, fix missing clk_prepare
   when using old dt name and nit pick in MOUDLE_ALIAS in TI PHYs.
