[PATCH v8 0/8] phy: omap-usb: Support multiple instances and new types

[Roger Quadros]

Hi,

This patchset does the following:

* Get rid of omap_control_usb platform data as we support DT only.

* Restructure and add support for new PHY types. We now support the following
four types

 TYPE_OTGHS - if it has otghs_control mailbox register (e.g. on OMAP4)
 TYPE_USB2 - if it has Power down bit in control_dev_conf register. e.g. USB2 PHY
 TYPE_PIPE3 - if it has DPLL and individual Rx & Tx power control. e.g. USB3 PHY or SATA PHY
 TYPE_DRA7USB2 - if it has both power down and power aux registers. e.g. USB2 PHY on DRA7

* Get rid of "ti,type" DT property and introduce compatible strings for each type.

* Have only one power control API "omap_control_usb_phy_power()" instead of a
different one for each PHY type.

* Get rid of omap_get_control_dev() so that we can support multiple instances
of the control device. We take advantage of the fact that omap control USB device
is only present on OMAP4 onwards and hence only supports DT boot. The users
of control USB device can get a reference to it from the device node's phandle.

Patches are based on greg/usb-next.

Smoke tested on OMAP4 panda with MUSB in gadget mode (g_zero).

You can find the patches in branch
 usb-control-module
in git tree
 git://github.com/rogerq/linux.git

v8:
- Rebased on top of greg/usb-next to avoid conflicts
- Removed patches 9 and 10 as they are not applicable

v7:
- Rebased on v3.12-rc1
- Updated DT compatibility ID for better readability
- Renamed TYPE_OMAP4 to TYPE_OTGHS, TYPE_USB3 to TYPE_PIPE3 and TYPE_DRA7 to
  TYPE_DRA7USB2

v6:
- addressed review comment about usage of control_usb before allocation.

v5:
- fixed whitespace alignment issues.

v4:
- removed "ti,has-mailbox" from omap-usb binding document example.

v3:
- return -EINVAL instead of -ENODEV on probe failure.
- pass device type data through of_device_id table.
- get rid of "ti,mailbox" property and "has_mailbox" from musb platform data.

v2:
- get rid of "ti,type" property and introduce compatible strings for each device type.

cheers,
-roger
