Hence, move i2c0 EEPROM device node from Keystone SoC to

installed.

This is likely a copy-and-paste error from the
ARM GIC documentation, that has already been fixed.
address-cells should have been set to 0, as with the size
cells. As having those properties set to 0 is the
same thing as not specifying them, drop them completely.

On N900 there are nice LEDs that show the state of the
sys_clkreq and sys_off_mode pins.
These LEDs go low when the system enters deeper idle
states. The left LED shows the state of the sys_clkreq
pin, and goes off during retention idle. The right LED
shows the state of sys_off_mode pin and both go off
during off idle.
As N900 is a battery operated device, these LEDs should
be off most of the time. So let's enable them by default
so we can make sure the system is mostly idle.
This allows the maintainers to also immediately test
patches for PM regressions by looking at the LEDs,
which certainly makes my life easier.
The LED can naturally be disabled during runtime with:
# echo none > /sys/class/leds/debug::sleep/trigger
Note that we don't currently have support for omap3
errata 1.158 that remuxes GPIO pins to INPUT_PULLUP |
MUX_MODE7 for the duration of idle. This means that the
GPIO pins set high will go down during off idle. In this
case it does not matter as the sys_off_mode goes down
too, but there's still a slim chance of false off idle
LED signals. If in doubt, false LED signals can be
verified by the sys_off_mode or vdd_core values.
Also note that to allow the UARTs to autoidle, the
following needs to be run on N900 to enable off idle:
#!/bin/sh
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode
For retention idle, change the above to set 0 to
enable_off_mode.
Also note that without the twl4030 PM scripts the actual
voltage scaling won't happen for off idle so we only get
voltage scaling over I2C4 for retention idle. I'll do
some device tree patches for those also a bit later on.

Almost certainly any sane board has the twl4030 has the I2C4
pins connected as those are needed for voltage control during
idle. If the I2C4 lines are not properly muxed, any voltage
scaling over I2C4 will fail.
Let's mux those pins by default, the boards that are not using
them can still configure things separately.

We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee1786 (pinctrl: single: Add support for wake-up interrupts)
that recently got merged. In addition to that we also needed commit
79d9701559 (of/irq: create interrupts-extended property) and
9ec36cafe4 (of/irq: do irq resolution in platform_get_irq) that
are now also merged.
So let's fix the wake-up events for some selected omaps so devices
booted in device tree mode won't just hang if deeper power states
are enabled, and so systems can wake up from suspend to the serial
port event.
Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.

With ARCH_OMAP2PLUS being separated out into OMAP2/3/4/5 etc all the TI device
tree blobs are built no matter the combination of SoCs that are enabled. This
often causes a bunch of irrelevant .dts to be built on a multi platform kernel,
this enables the building of just the ones relevant to the SoCs that are
actually enabled. It also orders the dts file alphabetically.
This also helps to avoid trivial merge conflicts when adding support
for new boards.
