Subject: [PATCH v5 RESEND 0/3] Add Combo PHY driver for HiSilicon STB SoCs

Hi Kishon，

This is a resend of v5 [1], which has been there for a quite a while.
I rebased it on next-20180119.  Please let me know if you have any
comments.

It adds device tree bindings and driver support for Combo PHY device
which can be found on HiSilicon STB SoCs.

Changes for v5:
 - Add bindings doc for Hi3798CV200 peripheral controller, and refer to
   the bindings of this parent node in combphy bindings doc.

Changes for v4:
 - Instead of relying on device id, add a new property
   hisilicon,fixed-mode for combphy device that doesn't support mode
   select but a fixed phy mode.
 - Move combphy mode select register bits definition to device tree, as
   it may vary from one device to another.

Changes for v3:
 - Make combphy device be child of peripheral controller and use 'reg'
   property for mapping combphy configuration registers.
 - Kill "hisilicon,peripheral-syscon" property, since parent node is
   just the syscon controller now.
 - Check combphy id to handle the quirk that combphy0 can not configure
   mode but always works in USB3 mode.
 - Unify phy .init and .exit hooks for different combphy instances and
   work modes, as the only quirk we need to handle is that combphy0 can
   only work in USB3 mode.
 - Better naming for clock and reset, 'ref' to 'ref_clk', 'por' to
   'por_rst'.

Changes for v2:
 - Move DT bindings into a separate patch.
 - Drop the spurious newline from drivers/phy/Makefile.
 - Use the phy type defines in dt-bindings/phy/phy.h.
 - Use PTR_ERR_OR_ZERO() for checking return from
   devm_of_phy_provider_register().
 - Add USB3 phy support.
