Pull ARM SoC platform updates from Olof Johansson:
 "SoC updates, mostly refactorings and cleanups of old legacy platforms.

  Major themes this release:

   - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)

   - Moving some of the ep93xx headers around to get it closer to
     multiplatform enabled.

   - Cleanups of Davinci

  This also contains a few patches that were queued up as fixes before
  5.1 but I didn't get sent in before release"

This update for DaVinci SoC support simplifies the VBUS enable

vbus GPIO as a regulator. This unifies code for all users, device
tree and non-device-tree.

The OHCI driver patches have been acked by its maintainer.

The configure endpoint command configures all the endpoints that were
flagged to be added or dropped.

To know the content of each of the added endpoints we need to add tracing
to the .add_endpoint() callback, just after initializing all the context
values.

Improve port related dynamic debugging by printing out the bus number,
port number and port status register content each time there is a port
related debug messages.

Use the same port numbering method as usbcore to simplify debugging.
i.e. starting with port number 1.

<title>usb: xhci: add Immediate Data Transfer support</title>

<content type='text'>
Immediate data transfers (IDT) allow the HCD to copy small chunks of
data (up to 8bytes) directly into its output transfer TRBs. This avoids
the somewhat expensive DMA mappings that are performed by default on
most URBs submissions.

In the case an URB was suitable for IDT. The data is directly copied
into the "Data Buffer Pointer" region of the TRB and the IDT flag is
set. Instead of triggering memory accesses the HC will use the data
directly.

The implementation could cover all kind of output endpoints. Yet
Isochronous endpoints are bypassed as I was unable to find one that
matched IDT's constraints. As we try to bypass the default DMA mappings
on URB buffers we'd need to find a Isochronous device with an
urb-&gt;transfer_buffer_length &lt;= 8 bytes.

The implementation takes into account that the 8 byte buffers provided
by the URB will never cross a 64KB boundary.

When the driver tries to get optional clock, it ignores all errors except
-EPROBE_DEFER, but if only ignores -ENOENT, it will cover some real errors,
such as -ENOMEM, so use devm_clk_get_optional() to get optional clock.

Use devm_clk_get_optional() to get optional clock instead of
optional_clk_get() which uses devm_clk_get() to get clock and
checks for -EPROBE_DEFER but not -ENOENT as devm_clk_get_optional()
does, in fact, only ignoring -ENOENT will cover more errors, so the
replacement doesn't change original purpose.
