[PATCH v9 0/4] Add a new Rockchip usb2 phy driver

From: Frank Wang
Date: Fri Jul 22 2016 - 03:01:39 EST

The newer SoCs (rk3366, rk3399) of Rock-chip take a different usb-phy
IP block than rk3288 and before, and most of phy-related registers are
also different from the past, so a new phy driver is required necessarily.

These series patch add phy-rockchip-inno-usb2.c and the corresponding

Changes in v9:
- Move the usb gpio config from dtsi to dts.
- Add vin-supply (vcc5v0_sys) for vcc5v0_host.
- Change some properties' name.

Changes in v8:
- Added support for rk3399 SoC.
- Prepare input clock of phy at probe time.
- Improved sm_work function to handle phy-port state more clearly.

Changes in v7:
- Renamed functions *usb2phy_resume/*usb2phy_suspend to *usb2phy_power_on/usb2phy_power_off.

Changes in v6:
- Changed '_' to '-' for otg-id and otg-bvalid property in devicetree bindings.
- Fixed the output clock would be disabled more than once while phy-port was going to suspend.
- Improved the driver to avoid the currently empty otg-port would cause null-pointer dereferences.

Changes in v5:
- Added 'reg' property both in devicetree bindings and driver to match the different phy-blocks.

Changes in v4:
- Used 'phy-supply' instead of 'vbus_*-supply'.

Changes in v3:
- Supplemented some hardware-description into the devicetree bindings.
- Resolved the mapping defect between fixed value in driver and the property
in devicetree.
- Code cleanup.

Changes in v2:
- Specified more hardware-description into the devicetree bindings.
- Optimized some process of driver.
