The LED nodes can be shared between Odroid XU3, XU3-Lite and XU (not yet
added) thus removing duplication.

DWC3 device found on Exynos SoCs cannot work in OTG mode alone, because
it lacks some OTG related control part. OTG mode operation is possible
only with external hardware logic (usually GPIO-based) specific to
the board. Right now, however, there is no driver for such logic and no
bindings, so the OTG mode is dysfunctional at all (this means that it
doesn't work as a peripheral nor as a host). This patch sets the operation
mode to peripheral to get DWC3_1 device at least somehow working. This can
be later updated, when proper OTG driver and bindings get developed.

Add Hardkernel Odroid XU4 board Device Tree sources. The board differs
from Odroid XU3 and XU3-Lite by:
1. No green and red LEDs (except standard red power LED).
2. Only two PWM outputs are used (fan and blue LED)
3. No audio codec.
4. Two USB3 ports in host mode (no micro USB3 connector for OTG).
5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514).
6. Additional connector with IO ports (I2S_0, I2C_5).
7. No DisplayPort (like XU3-Lite).
8. No TI INA231 power measurement sensors (like XU3-Lite).

The Odroid XU4 board does not have audio codec so before adding DTS
for new board split the audio codec to separate DTSI file. Include
the audio codec DTSI in Odroid XU3 and XU3-Lite boards.

The Odroid XU3 Lite is almost the same as XU3, except:
1. Lower CPU frequencies (1.8 GHz for A15 and 1.3 GHz for A7, instead of
2.0 GHz and 1.4 GHz).
2. No DisplayPort.
3. No TI INA231 energy measurement sensors.
This patch moves common nodes (which is almost everything) to a common
DTSI file and adds a new XU3 Lite DTS.
Currently in comparison to XU3, only the INA231 sensors are disabled to
remove the warning:
ina2xx 0-0040: error configuring the device: -6

The IRQB of S2MPS11 PMIC is wired to XEINT4 (GPX0-4) through pull-up
resistor.
Add interrupt properties and pinctrl configuration to enable RTC wake
alarm of rtc-s5m driver. This also removes a warning:
sec_pmic 4-0066: No interrupt specified, no interrupts

PWM output wasn't working because it wasn't hooked up to its pincontrol.
This patch:
- hooks up PWM to its pincontrol, and documents what
the outputs are on the XU3
- switches the LEDs that are on PWM outputs to use PWM
rather than GPIO.
The main effect is that the brightness of the LEDs can be controlled, and
user-mode fan control is enabled via /sys/class/pwm

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.
Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:
* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]
The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.
But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.
It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.
Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

Last 22 MiB is RAM is reserved by secure monitor code and cannot be

The odroid-xu3 has 4 INA231 current sensors on board which can be
accessed from the Linux via the hwmon interface.
There is one sensor for each of these power rails:
- A15 cluster: VDD_ARM
- A7 cluster: VDD_KFC
- GPU: VDD_G3D
- memory: VDD_MEM
In addition to adding the sensors, LDO26 from the PMIC needs to be
enabled because it's powering these sensor.

Add DTS for the Hardkernel Odroid XU3. The name of the DTS file is
kept the same as the vendors naming, which means it's prefixed with
exynos5422 instead of exynos5800 as the SoC name even though it
includes the exyno5800 dtsi.
