Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
Audio DMAC peri peri DMAEngine is no longer needed.

In commit 87517d26 ("ARM: dts: dra7-evm: Add extcon nodes for USB")
we enabled Extcon USB gpio to tackle the USB ID pin and get
peripheral mode to work.

But the extcon-gpio-usb driver [1] didn't make it into v4.0
and this makes the USB driver defer probe indefinitely breaking
USB Host functionality.

As a temporary fix we remove the extcon handle from the
USB controller and add it back when the extcon driver
merges in v4.1.

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not
detect smc91x ethernet hardware in qemu N900 machine.

The 0x300 offset was used to supress a warning the smsc911x
driver produces about non-standard offset as 0x300 seems to
be the EEPROM default. As only three address lines are
connected both 0 and 0x300 will work just fine with 0 being
correct. The warning about the non-standard offset can be
fixed by writing to EEPROM as that's needed in any case to
set the MAC address.

Commit 7800064b ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the USB completely because of an unconfigured USB phy, and
I only tested it to make sure the Mentor chips are detected and
clocked without a phy.

After testing the USB with actual devices I noticed a few issues
that should be fixed to avoid confusion:

- The USB id pin on dm8168-evm is hardwired and can be changed
  only by software. As there are two USB-A type connectors, let's
  start both in host mode instead of otg.

- The Mentor core is configured in such a way on dm8168-evm that
  it's not capable of multipoint at least on revision c board
  that I have.

- We need ranges for the syscon to properly set up the phy as
  children of the SCM syscon area.

- Let's not disable the second interface, the board specific
  dts files can do that if really needed. Most boards should
  just keep it enabled to ensure the device is idled properly.

Note that also a phy and several musb fixes are still needed to
make the USB to work properly in addition to this fix.

There doesn't seem to be any valid reason to allocate the pages array
with the same flags as the buffer itself. Doing so can eventually lead
to the following safeguard in mm/slab.c's cache_grow() to be hit:

        if (unlikely(flags & GFP_SLAB_BUG_MASK)) {
                pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK);
                BUG();
        }

This happens when buffers are allocated with __GFP_DMA32 or
__GFP_HIGHMEM.

Fix this by allocating the pages array with GFP_KERNEL to follow what is
done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer()
is safe because atomic allocations are handled by __iommu_alloc_atomic().
