Subject: [RFC PATCH 00/10] omap: musb: Add device tree support

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.

This series was developed on
http://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-next

However to test this patch series, the following patch series is needed
[PATCH v7 0/3] usb: multi-phy support
[PATCH v3 0/5] usb: musb: cleanup
[RFC PATCH 00/11] OMAP System Control Module
[RFC PATCH v2 0/2] omap: add ocp2scp as a misc driver

Performed device mode testing on OMAP4 panda and OMAP3 beagle.
