Subject: [RFC PATCH 0/3] usb: musb: add new phy driver

This series adds a new usb2 phy driver. The device for which is created
by the ocp2scp driver. This also uses control module driver.

This series converts twl6030 as a comparator driver (previously it was
also the phy driver) and makes use of omap-usb2 as the phy driver.

Instead of notification mechanism by power chip to omap glue to pass detection
of any events, an export API has been added in omap glue. Both twl4030 and
twl6030 will call to this API to pass any event. (twl6030 is used in omap4 and
twl4030 is used in omap3).

This series depends on:
*[RFC PATCH 00/11] OMAP System Control Module* patch series
However System Control Module driver has only dt support, so wouldn't
be able to test this patch series. However I'll adapt omap usb2 phy
driver and musb driver for dt and send it asap to the list.

This series also depends on:
*[PATCH v3 0/3] usb: multi-phy support* patch series
*[RFC PATCH 0/5] omap: add ocp2scp as a misc driver* patch series

Compile tested only.

Kishon Vijay Abraham I (3):
  drivers: usb: otg: add a new driver for omap usb2 phy
  usb: musb: omap glue: use omap-usb2 as the phy driver
  arm: omap: phy: remove unused functions from omap-phy-internal.c
