[PATCH v2 0/4] phy: socionext: add new UniPhier USB PHY driver support

[Kunihiko Hayashi]

This series adds support for PHY interface built into USB controller
implemented in Socionext UniPhier SoCs.

The USB3 PHY driver supports High-Speed PHY and Super-Speed PHY included in
the USB3 glue layer, and the USB2 PHY driver supports High-Speed PHY
integrated into system controller.

Kunihiko Hayashi (4):
  dt-bindings: phy: add DT bindings for UniPhier USB3 PHY driver
  phy: socionext: add USB3 PHY driver for UniPhier SoC
  dt-bindings: phy: add DT bindings for UniPhier USB2 PHY driver
  phy: socionext: add USB2 PHY driver for UniPhier SoC

Changes since v1:
- rewrite a header with C++ comment style
- dt-bindings: separate a document for ssphy and hsphy
- dt-bindings: sort clock-names and reset-names to begin with "phy"
- dt-bindings: use vbus-supply instead of phy-supply, because vbus isn't
  for phy, but vbus is tied to the port that corresponds to each phy [1]
- stop using phy_power and add own .power_on and .power_off functions
  to control clk/reset for phy and vbus regulator
- separate clk_get() and reset_control_get() for each clk/reset
  and remove arrays of clock_names and reset_names
- remove phy-parameters that are the same as power-on values
- remove functions to set phy-parameters for legacy SoCs
- express phy-parameters by using macros including the number of
  the register and its bitfield (msb and lsb)
