Odroid-C1 exposes ADC channels 0 and 1 on the GPIO headers. NOTE: Due

There are multiple fixed regulators on the Odroid-C1 board. Add them so
they can be used when we add the devices that need them (SAR ADC needs
the 1.8V IOREF, RTC needs VDD_RTC).
These are:
- P5V0 is the main 5V power input
- VCC3V3 / VDDIO_AO3V3 / VDD3V3: fixed regulator with 3.3V output which
is supplied by P5V0
- IOREF_1V8 / VCC1V8 / VDD1V8: fixed regulator with 1.8V output which is
supplied by P5V0
- VDD_RTC: fixed voltage regulator with 0.9V output which is supplied by
VDDIO_AO3V3
- DDR_VDDC / DDR3_1V5: fixed voltage regulator with 1.5V output which is
supplied by P5V0
- the existing TF_IO and RFLASH_VDD_EN regulators are supplied by
VDDIO_AO3V3
- the existing VCCK regulator is supplied by P5V0
This does not add the missing VDDEE regulator (controlled by PWM_D)
because it's not clear yet how to configure the voltage of that
regulator.

The CPU voltage regulator is a "Monolithic Power Systems MP2161"
(according to the Odroid-C1+'s schematics). It is driven by PWM_C on
GPIODV_9.
Hardkernel's 3.10 kernel (based on the Amlogic GPL kernel sources)
defines a PWM voltage table with the following values:
- 0.86 volts = PWM register value 0x10f001b
- (more values in 0.1 volt increments)
- 1.14 volts = PWM register value 0x000012a
When using the XTAL (24MHz) as input this translates into a PWM period
of 12218ns with 0.86V using a duty cycle of 91% and 1.14V using a duty
cycle of 0%.

The Endless Mini (EC-100) is a grapefruit-sized computer based on the
Amlogic Meson8b (S805) SoC which comes in two variants.
Both variants have in common:
- Amlogic Meson8b (S805) SoC
- two USB 2.0 ports on the rear, one one the front (connected to the SoC
through an internal hub)
- 3.5mm Stereo out and MIC combo port
- HDMI and CVBS output
- 5V power supply (rated at 3A / 15W)
- an internal embedded micro-controller (called "EC") which implements a
"breathing" effect for the LED and allows shutting down (powering off)
the whole device
- 10/100 Mbit/s Ethernet using an IC Plus IP101A/G PHY (note: the website
incorrectly lists a Gigabit Ethernet port)
- the CPU voltage is regulated using a PWM regulator. The GPL sources of
the EC-100 are using a PWM value of 0x1c0000 for 0.86V and a PWM value
of 0x00001c for 1.14V. When using the XTAL (24MHz) as input this
translates into a PWM period of 1148ns with 0.86V using a duty cycle of
100% and 1.14V using a duty cycle of 0%.
The main differences are:
- the main indicator for the variant is the RAM size: the "cheaper"
variant has 1 GB of RAM, while the more expensive one comes with 2GB
- the storage size differs: 24 GB vs 32 GB
- the "1 GB RAM" variant has Ethernet connectivity only, while the "2 GB"
variant has a Realtek RTL8723BS SDIO chip which adds 802.11b/g/n wifi
and Bluetooth 4.0 support

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.
