[PATCH v4 00/17] Add power management support for mxs phy

[Peter Chen <peter.chen-KZfg59tc24xl57MIdRCFDg@public.gmane.org>]

Hi Felipe & Shawn,

The serial adds power management support for MXS PHY, it includes:

- Add three common PHY APIs, .set_wakeup, .notify_suspend, notify_resume.
- Related above 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 Greg's usb-next, 3.13-rc1.

Changes for v4:
- Using MXS_PHY_HAS_ANATOP to indicate which platform has anatop module
- Using mxs_phy_data to instead of mxs_phy_platform_flag
- Create is_xxx_phy() MACRO
- Add imx6sl support, and pass the test [5/17]
- Add one additional binding doc for compatible string [1/17]
- Introduce controller id to access un-regulator register region
[14/17] [15/17]
- Add waiting stable time before phy clock switches to AHB clock
(from 32K) [13/17]
- Fix one problem that only using the 1st controller register
at mxs_phy_disconnect_line [16/17]
- Fix one problem for low speed connection at very rare cases [17/17]
- Some typos


Changes for v3:
- Using flag bit to indicate SoC features/bugs, so we can remove
platform_device_id.
- Remove 3 unnecessary dts/doc patches due to above change
- Several comment change

Changes for v2:

- Add missing patches which introduce platform judgement code [1/14,2/14]
- re-order the patch sequence, like doc->dts->source file,
the reviewers can know the meaning of dt properties before review source
- Add description of two IC problems exsiting at mxs PHY; change
"high speed" to "HS" and "non-high speed" to "FS/LS" [5/14]
- Change the dt property disconnect-line-without-vbus
that the separator should be "-" not the "_", meanwhile, related source
code has changed.
- Using one local variable to get the function return val to avoid long
condition statement. [13/14]
