The AON GPIO controller is in an always-on power partition and typically

The on-die RTC isn't hooked up to a backup battery, so it isn't useful
to track time across reboots, but as long as power remains enabled, it
keeps track of time accurately and can be used to wake the system from
sleep, for example.

The RTC on Tegra194 is very similar to the RTC on earlier generations.
One notable exception is that the source clock is now the 32 kHz clock
instead of a dedicated RTC clock and the RTC alarm is a wake event and
can be used to wake the system from sleep.

Wake events are a feature that allows the interrupt and GPIO controllers
to be powered off as part of system sleep. The PMC which is always on is
monitoring these wake events and can power up subsequent controllers as
necessary to process them.

Add iio-hwmon-battery using adc channel 12 and enable adc to make
adc running. This channel is used to read RTC battery voltage.
Note with Romulus hardware design, it requires GPIOR3 to be pulled
high to read the voltage, otherwise the reading is 0.
When GPIOR3 is high, it consumes battery and impacts the battery life.
So it is left for user space to toggle the GPIO when trying to read the
voltage.

The base aspeed-g5.dtsi already defines a '/memory@80000000' node, so
'/memory' in the board files create a duplicate node. We're probably
getting lucky that the bootloader fixes up the memory node that the
kernel ends up using. Add the unit-address so it's merged with the base
node.
Found with DT json-schema checks.

There's a bug in dtc in checking for duplicate node names when there's
another section (e.g. "/ { };"). In this case, skeleton.dtsi provides
another section. Upon removal of skeleton.dtsi, the dtb fails to build
due to a duplicate node 'fixedregulator@0'. As both nodes were pretty
much the same 3.3V fixed regulator, it hasn't really mattered. Fix this
by renaming the nodes to something unique. In the process, drop the
unit-address which shouldn't be present wtihout reg property.

Marvell keeps their MMP2 datasheet secret, but there are good clues
that TWSI2 is not on 0xd4025000 on that platform, not does it use
IRQ 58. In fact, the IRQ 58 on MMP2 seems to be a signal processor:
arch/arm/mach-mmp/irqs.h:#define IRQ_MMP2_MSP 58
I'm taking a somewhat educated guess that is probably a copy & paste
error from PXA168 or PXA910 and that the real controller in fact hides
at address 0xd4031000 and uses an interrupt line multiplexed via IRQ 17.
I'm also copying some properties from TWSI1 that were missing or
incorrect.
Tested on a OLPC XO 1.75 machine, where the RTC is on TWSI2.
