Add combo phy driver for HiSilicon STB SoCs. This phy can be
used as pcie-phy, sata-phy or usb-phy.
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.
