Since turning on idle-halt in commit fe46aa67 (ARM: at91/dt: add
sam9 watchdog default options to SoCs), SoCs compatible with at91sam9260-wdt
no longer reboot if the watchdog times out while the CPU is in idle state.
Removing the 'idle-halt' flag that was set by default fixes this.

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

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.

"isil" and "isl" prefixes are used at various locations inside the kernel
to reference Intersil corporation.  This patch is part of a series fixing
those locations were "isl" is used in compatible strings to use the now

version).

Note: isl9305 is an I2C device so the patch does not in fact currently
depend on the introduction of "isil"-based compatible string in isl9305
driver (provided by another patch) because I2C core does not check the
prefix yet.

Now that alarm support for ISL12057 chip is available w/ the specific
"isil,irq2-can-wakeup-machine" property, let's use that feature of the
driver dedicated to NETGEAR ReadyNAS 102, 104 and 2120 specific routing of
RTC Alarm IRQ#2 pin; on those devices, this pin is not connected to the
SoC but to a PMIC, which allows the device to be powered up when RTC alarm
rings.

For that to work, the chip needs to be explicitly marked as a device
wakeup source using this "isil,irq2-can-wakeup-machine" boolean property.
This makes 'wakealarm' sysfs entry available to configure the alarm.
