a710d10d02 ARM: dts: Remove PIN_INPUT for dm816x McSPI
On dm816x we have no PIN_INPUT vs PIN_OUTPUT configuration, there
are just pulls. Let's remove the bogus flags.

3438bd2e7b ARM: dts: Fix typo for dm816x usb0_pins
Commit a54879a008 ("ARM: dts: Fix USB dts configuration for dm816x")
attempted to fix the USB features introduced by commit 7800064ba5
("ARM: dts: Add basic dm816x device tree configuration") but obviously
I did not read the dmesg as more USB issues still keep trickling in.

It should be usb1_pins instead not usb0_pins for the second interface
to avoid warnings from pinctrl framework.

a54879a008 ARM: dts: Fix USB dts configuration for dm816x
Commit 7800064ba5 ("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.

ac7452cee7 ARM: dts: Add minimal support for dm8168-evm
This allows booting the device with basic functionality.

Note that at least on my revision c board the DDR3 does
not seem to work properly and only some of the memory
can be reliably used.

Also, the mainline u-boot does not seem to properly
initialize the ethernet, so I've been using the old TI
u-boot at:
