Add clock enable/disable at .set_suspend if the PHY has
suspend requirement, it can be benefit of power saving for
phy and the whole system (parent clock may also be disabled).

This USB controller can work in as host-only, gadget-only or dual-role

This is just a resend of a recently sent, standalone patch.

I'm resending this configuration rework to include one more patch in the
series, prior to the config change. The first patch removes the usb_disable()
usage, allowing the build the module for gadget-only mode usage.
Without the first patch, the build breaks when building for !USB && USB_GADGET.
Ho
Removing the check to usb_disable() before registering the platform
driver allows to build this driver when !USB && USB_GADGET, to be
used in gadget-only mode.
Also, use module_platform_driver() to register the platform driver.

Hi all,
my tree is now closed for v3.14 merge window. I'm testing a few last

Hi Greg,
Here's my overly extensive pull request for v3.14 merge window. Lots

Adjust the code to make it easy to add the settings for the new chip.
Then, add the relative parameters of the RTL8153.
Hayes Wang (6):
r8152: move rtl8152_unload and ocp_reg_write
r8152: modify the method of accessing PHY
r8152: change some definitions
r8152: add rtl_ops
r8152: split rt
Change the locations of rtl8152_unload() and ocp_reg_write().

The auto setting is used to open related power and clocks
automatically after receiving wakeup signal.
With this feature, the PHY's clock and power can be recovered
correctly from low power mode, it is guaranteed by IC logic.

Hi Felipe & Shawn,
The serial adds power management support for MXS PHY, it includes:
- Add one PHY API .set_wakeup, and related API implementation at mxs phy driver
- misc changes and bug fixes for mxs phy to support low power mode and wakeup.
It is based on the lastest Greg's usb-next, 3.13-rc
The mxs-phy has several bugs and features at different
versions, the driver code can get it through of_device_id.data.

We need this to keep PHY's power on or off during the system
suspend mode. If we need to enable USB wakeup, then we
must keep PHY's power being on during the system suspend mode.
Otherwise, we need to keep PHY's power being off to save power.

When we need the PHY can be waken up by external signals,
we can call this API. Besides, we call mxs_phy_disconnect_line
at this API to close the connection between USB PHY and
controller, after that, the line state from controller is SE0.
Once the PHY is out of power, without calling mxs_phy_disco
This API is used to set wakeup enable at PHY registers, in that
case, the PHY can be waken up from suspend due to external events,
like vbus change, dp/dm change and id change.

Two PHY bugs are fixed by IC logic, but these bits are not
enabled by default, so we enable them at driver.
The two bugs are: MXS_PHY_ABNORMAL_IN_SUSPEND and MXS_PHY_SENDING_SOF_TOO_FAST
