[PATCH v7 0/7] omap: musb: Add device tree support

[Kishon Vijay Abraham I <kishon@ti.com>]

This patch series adds device tree support for MUSB and device
tree support for all the related modules to get MUSB working in
OMAP platform.

A new omap-usb2 phy driver has been added (with only dt suppport)
to perform phy configurations. Previously this configuration was
performed by twl6030, using pdata function pointers.

With the addition of omap-usb2 to perform phy configurations,
twl6030 is made as a comparator driver to detect VBUS and ID events
and notify it to the glue layer.

musb core is _NOT_ yet converted to support device tree support as it
would need lot of driver re-design because of its enormous use of
function pointers. That will be in _TO DO_ list.

Changes from v6:
* Removed the dt data part of the patch series. It'll be sent as a
separate series.
* Replaced arch initcall in omap-usb2 phy driver with a module
platform driver. Dependent drivers should use -EPROBE_DEFER. 

Changes from v5:
minor cleanups like checking for return value in get_sync and few changes
in the documentation has been done.

Changes from v4:
duplicate getting of 'mode' property is removed in omap-musb glue.

Changes from v3:
remove the address in the node name of usb_otg_hs since the usb_otg_hs
node doesn't have a reg property. Thanks Ajay Gupta for finding this.

Changes from v2:
Fixed Sergei's comment to remove *0x* prefix in usb2phy@0x4a0ad080

Changes from v1:
* Fixed Rajendra Nayak comments (regulator naming, compatible naming of
musb and other minor cleanups.)
* It's agreed to have ocp2scp in drivers/bus and usb2 phy is a child of
ocp2scp, the documentation is updated accordingly.

Changes from RFC:
Removed the dependency on [RFC PATCH 00/11] OMAP System Control Module.
Writing to control module register is now handled in otg driver itself.
Once the system control module driver get upstreamed, I'll send a patch
to make use of API's in control module driver to write to control
module register.

This patch series depends on
[PATCH v3 0/2] omap: add ocp2scp as a bus driver

Performed MUSB device mode testing on OMAP4 panda, OMAP4 SDP
and OMAP3 beagle.
