[PATCH v7 0/5] Patches to add support for Rockchip usb PHYs.

[Yunzhi Li]

Patches to add support for Rockchip usb phys.Add a new Rockchip
usb phy driver and modify dwc2 controller driver to make dwc2
platform devices support a generic PHY framework driver. This
patch set has been tested on my rk3288-evb and power off the usb
phys would reduce about 60mW power budget in total during sustem
suspend.

Changes in v7:
- Update bindings doc
- Accept Kishon's comments to use phandle args to find a phy
  struct directly and get rid of using a custom of_xlate
  function.
- Update dtsi for new usb phy driver.

Changes in v6:
- Rename SIDDQ_MSK to SIDDQ_WRITE_ENA.

Changes in v5:
- Adjust entry order of example devicetree node in document.
- reorder the phy dt node to a correct position.

Changes in v4:
- Updata description for phy device tree subnode.
- Get number of PHYs from device tree.
- Model each PHY as subnode of the phy provider node.
- Add phy subnodes.

Changes in v3:
- Use BIT macro instead of bit shift ops.
- Rename the config entry to PHY_ROCKCHIP_USB.
- Fix coding style: both branches of the if() which only one
  branch of the conditional statement is a single statement
  should have braces.
- No need to test dwc2->phy for NULL before calling generic phy
  APIs.

it seems I missed a mail stating that the phy driver was applied and just
found it in the main tree during the merge window.

I've therefore applied the two dts patches for 3.21 and put the following
on top, so that the firefly board also gets phy support
