The operating points should correspond to the actual frequencies
supported for the CPU. Other patches have fixed so these are
rounded and reported properly, this fixes the device trees to
match.
The Codina variant has a lower frequency than other devices so
indicate this in the device tree.

While 7e5f3155dc ("ARM: dts: stm32: Fix LED5 on STM32MP1 DHCOM PDK2")
fixed the LED0 assignment on the PDK2 board, the same commit did not
update the touchscreen IRQ line assignment, which is the same GPIO line,
shared between the LED0 output and touchscreen IRQ input. To make this
more convoluted, the same EXTI input (not the same GPIO line) is shared
between Button B which is Active-Low IRQ, and touchscreen IRQ which is
Edge-Falling IRQ, which cannot be used at the same time. In case the LCD
board with touchscreen is in use, which is the case here, LED0 must be
disabled, Button B must be polled, so the touchscreen interrupt works as
it should.
Update the touchscreen IRQ line assignment, disable LED0 and use polled
GPIO button driver for Button B, since the DT here describes baseboard
with LCD board.

The LAN8710 Energy Detect Power Down (EDPD) functionality might cause
unreliable cable detection. There are multiple accounts of this in the
SMSC PHY driver patches which attempted to make EDPD reliable, however
it seems there is always some sort of corner case left. Unfortunatelly,
there is no errata documented which would confirm this to be a silicon
bug on the LAN87xx series of PHYs (LAN8700, LAN8710, LAN8720 at least).
Disable EDPD on the DHCOM SoM, just like multiple other boards already
do as well, to make the cable detection reliable.

The DHCOM SoM has two RTC, one is the STM32 RTC built into the SoC
and another is Microcrystal RV RTC. By default, only the later has
battery backup, the former does not. The order in which the RTCs
are probed on boot is random, which means the kernel might pick up
system time from the STM32 RTC which has no battery backup. This
then leads to incorrect initial system time setup, even though the
HW RTC has correct time configured in it.
Add DT alias entries, so that the RTCs get assigned fixed IDs and
the HW RTC is always picked by the kernel as the default RTC, thus
resulting in correct system time in early userspace.

At the moment the AB8500 USB PHY driver still uses the old USB PHY
subsystem instead of the generic PHY subsystem. This means that there
is no explicit link between the USB controller and the USB PHY.
In U-Boot the PHY driver is integrated in the generic PHY subsystem,
so we need to use the typical PHY device tree bindings to specify
which PHY belongs to the USB controller.
Add the link between USB controller and PHY to both ste-ab8500.dtsi
and ste-ab8505.dtsi. This is mainly for U-Boot for now and will just
be ignored in Linux. However, if the AB8500 USB PHY driver in Linux
is moved to the generic PHY subsystem at some point these device tree
changes can be used as well.

This device tree include file describes a fixed-regulator
connecting smps7_reg output (1.8V) to some 1.8V rail and
consumers (vdds_1v8_main).
This regulator does not physically exist.
I assume it was introduced as a wrapper around smps7_reg
to provide a speaking signal name "vdds_1v8_main" as label.
This fixed-regulator without real function was not an issue
in driver code until
Commit 98e48cd928 ("regulator: core: resolve supply for boot-on/always-on regulators")
introduced a new check for regulator initialization which
makes Palmas regulator registration fail:
[ 5.407712] ldo1: supplied by vsys_cobra
[ 5.412748] ldo2: supplied by vsys_cobra
[ 5.417603] palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator
The reason is that the supply-chain of regulators is too
long and goes from ldo3 through the virtual vdds_1v8_main
regulator and then back to smps7. This adds a cross-dependency
of probing Palmas regulators and the fixed-regulator which
leads to probe deferral by the new check and is no longer
resolved.
Since we do not control what device tree files including this
one reference (either &vdds_1v8_main or &smps7_reg or both)
we keep both labels for smps7 for compatibility.

Based on the latest timing specifications for the TPS65218 from the data
sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
from November 2014, we must change the i2c bus speed to better fit within
the minimum high SCL time required for proper i2c transfer.
When running at 400khz, measurements show that SCL spends
0.8125 uS/1.666 uS high/low which violates the requirement for minimum
high period of SCL provided in datasheet Table 7.6 which is 1 uS.
Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.
Without this patch occasionally a voltage set operation from the kernel
will appear to have worked but the actual voltage reflected on the PMIC
will not have updated, causing problems especially with cpufreq that may
update to a higher OPP without actually raising the voltage on DCDC2,
leading to a hang.

We are seeing "imprecise external abort (0x1406)" errors during boot
(which then cause the whole board to hang) on Meson8 (but not Meson8m2).
These are observed while trying to access the GPU's registers when the
MALI clock is running at it's default setting of 24MHz. The 3.10 vendor
kernel uses 318.75MHz as "default" GPU frequency. Using that makes the
"imprecise external aborts" go away.
Add the assigned-clocks and assigned-clock-rates properties to also bump
the MALI clock to 318.75MHz before accessing any of it's registers.
