Samsung DTS ARM changes for v5.6
1. Couple ARM and wcore bus regulators on Exynos542x so higher
frequencies could be used with dynamic voltage and frequency scaling.
Enable this higher frequencies.
2. Correct the polarity of USB3503 hub GPIOs.
3. Adjust the bus frequencies (scaled with devfreq framework) on
Exynos5422 Odroid boards to match values possible to obtain from root
PLLs.
4. Add display to Tiny4412 board.
5. Cleanups and minor improvements.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

Currently the only Exynos5422-based boards that support bus frequency
scaling are Hardkernel's Odroid XU3/XU4/HC1. Move the bus related OPPs
to the boards DTS, because those OPPs heavily depend on the clock
topology and top PLL rates, which are being configured by the board's
bootloader.

In Odroid XU3 Lite board, the temperature levels reported for thermal
zone 0 were weird. In warm room:
/sys/class/thermal/thermal_zone0/temp:32000
/sys/class/thermal/thermal_zone1/temp:51000
/sys/class/thermal/thermal_zone2/temp:55000
/sys/class/thermal/thermal_zone3/temp:54000
/sys/class/thermal/thermal_zone4/temp:51000
Sometimes after booting the value was even equal to ambient temperature
which is highly unlikely to be a real temperature of sensor in SoC.
The thermal sensor's calibration (trimming) is based on fused values.
In case of the board above, the fused values are: 35, 52, 43, 58 and 43
(corresponding to each TMU device). However driver defined a minimum value
for fused data as 40 and for smaller values it was using a hard-coded 55
instead. This lead to mapping data from sensor to wrong temperatures
for thermal zone 0.
Various vendor 3.10 trees (Hardkernel's based on Samsung LSI, Artik 10)
do not impose any limits on fused values. Since we do not have any
knowledge about these limits, use 0 as a minimum accepted fused value.
This should essentially allow accepting any reasonable fused value thus
behaving like vendor driver.
The exynos5420-tmu-sensor-conf.dtsi is copied directly from existing
exynos4412 with one change - the samsung,tmu_min_efuse_value.

Merge tag 'samsung-dt-odroid-xu-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt
Topic branch for adding Exynos 5410 Odroid XU board for v4.8.
This brings support for Hardkernel's Odroid XU board. It was the first
design with big.LITTLE SoC from Samsung: Exynos5410. The board is not
very popular. Newer XU3 and XU4 got more attention.
Board details:
1. Exynos5410 octa-core (A15+A7, however as of now only one cluster is
enabled),
2. 2 GB DDR3 RAM,
3. PowerVR SGX544MP3 GPU (not enabled in DTS),
4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4,
5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of
revisions though),
6. eMMC 4.5 and microSD slots.

Move watchdog and Security SubSystem nodes from exynos5420.dtsi to file
shared with Exynos5410 and configure the clocks on the latter.

On Exynos5410 the SPI interrupt for second USB DWC3 (called DRD: Dual
Role Device) is different - 200 instead of 73.

The USI/HSI2C nodes can be mostly shared between Exynos5420 and
Exynos5410 so move them to common DTSI.

Move USB 3.0 DWC and 2.0 EHCI/OHCI nodes from exynos5420.dtsi to
exynos54xx.dtsi common for entire family. For Exynos542x/5800 this
should not have functional impact but for Exynos5410 this effectively
adds USB support.

The Exynos5410/542x/5800 are very similar designs. Create a new
DTSI with common nodes to remove DTS duplication. Although currently
only MCT and SysRAM are shared but in future more nodes will be added to
the common file.
The patch should not have functional impact.

Multi-Core Timer generates interrupts but it is not really an interrupt
controller so remove the "interrupt-controller" and "interrupt-cells"
properties. Additionally extend the length of mapped memory to cover all
registers (last SFR is at 0x0A40).

The conventions is to put SoC devices under 'soc' node. In fact other
our DTSes (like exynos3250.dtsi or exynos5410.dtsi) already follow it.
Adjust exynos5250 and exynos5420 DTSI to follow this convention. This is
also necessary for the upcoming change in exynos5410.dtsi to inherit
from common exynos5.dtsi.

Exynos5420 and Exynos5250 share some nodes: the PWM, syscon
(sysreg_system_controller) and first four I2C controllers. Move them to
parent DTSI to avoid duplication.
