[GIT PULL] phy: for 4.8 -rc

[Kishon Vijay Abraham I]

Hi Greg,

Please find the pull request for this -rc cycle below.
It has fixes to get host-only mode working in sun4i, fixes a compilation
error (failed to catch this earlier because of missing COMPILE_TEST) and
other minor fixes.

Consider merging it in this rc cycle. Let me know if I have to change
something.

Thanks
Kishon

[PATCH 1/4] phy-sun4i-usb: Add support for peripheral-only mode

[Kishon Vijay Abraham I]

From: Hans de Goede <hdegoede@redhat.com>

Use the new of_usb_get_dr_mode_by_phy() function to get the dr_mode
from the musb controller node instead of assuming that having an id_det
gpio means otg mode, and not having one means host mode.

Implement peripheral-only mode by adding a sun4i_usb_phy0_get_id_det
helper which looks at the dr_mode, always registering our extcon and
always monitoring vbus.

If dr_mode is not specified in the dts, do not register phy0 as we then
do not know how to treat it. This is actually a good thing as this means
we will not be registering phy0 on devices where the otg controller is
not enabled in the devicetree.

[PATCH 2/4] mfd: da8xx-cfgchip: New header file for CFGCHIP registers

[Kishon Vijay Abraham I]

From: David Lechner <david@lechnology.com>

Create a new header file for TI DA8XX SoC CFGCHIPx registers.
This will be used by a number of planned drivers including a new USB
PHY driver and common clock framework drivers.

The same defines *will* be removed from the platform_data header,
once all the users start using the new syscon device header.

This also fixes the following compiler error caused due to
a dependent patch not merged.
