Merge tag 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-next

Kishon writes:

New Features
============
*) Add driver for USB PHYs on sun9i
*) Add driver for USB PHY on dm816x
*) Modified exynos5-usbdrd driver to add support for Exynos5433 SoC

Fixes
=====
*) Fix power_on/power_off failure paths in some drivers
*) Make miphy365x use generic PHY type constants
*) Fix build errors due to missing export symbols in qcom-ufs driver
*) Make all the functions return proper error values

Cleanups
========
*) use PTR_ERR_OR_ZERO to simplify code
*) use devm_kcalloc instead of devm_kzalloc with multiply
*) remove un-necessary ifdef CONFIG_OF

+Allwinner sun9i USB PHY
+-----------------------

+Required properties:
+- compatible : should be one of
+  * allwinner,sun9i-a80-usb-phy
+- reg : a list of offset + length pairs
+- #phy-cells : from the generic phy bindings, must be 0
+- phy_type : "hsic" for HSIC usage;
+             other values or absence of this property indicates normal USB
+- clocks : phandle + clock specifier for the phy clocks
+- clock-names : depending on the "phy_type" property,
+  * "phy" for normal USB
+  * "hsic_480M", "hsic_12M" for HSIC
+- resets : a list of phandle + reset specifier pairs
+- reset-names : depending on the "phy_type" property,
+  * "phy" for normal USB
+  * "hsic" for HSIC
+
+Optional Properties:
+- phy-supply : from the generic phy bindings, a phandle to a regulator that
+               provides power to VBUS.
+
+It is recommended to list all clocks and resets available.
+The driver will only use those matching the phy_type.
+
