AM437x IDK has a TPS386000 supply voltage supervisor on the VDD_MPU rail
set to trigger undervoltage condition at 0.96V. Because of this, OPP50,
which is normally configured to 300MHz at 0.95V, must be disabled to
avoid triggering the undervoltage condition. Also mark OPP100 as the
suspend-opp as it is now our lowest OPP.

Due to a mistake in documentation the DS0_PULL_UP_DOWN_EN macro was
mistakenly defined as an active high bit, however setting the bit
actually disables the internal pull resistor on the pin, so correct this
macro and introduce a new DS0_PULL_UP_DOWN_DIS macro with the proper bit
value set now that the documentation has been updated.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have
leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have
leading 0s

Converted using the following command:

$ find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec \
sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" \
-e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings
separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before
the the opening curly brace:

https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve as a side effect warning:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format
error, expected "<lower>"

The metastability workaround causes Erratic errors [1]
on the HighSpeed USB PHY which can cause upto 2 seconds
delay in enumerating to a USB host while in Gadget mode.

Disable the Run/Stop metastability workaround to avoid this
ill effect. We are aware that this opens up the opportunity
for Run/Stop metastability, however this issue has never been
observed in TI releases so we think that Run/Stop metastability
is a lesser evil than the PHY Erratic errors. So disable it.

There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.

This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.

Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.

Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457 ("ARM: omap: convert
wakeupgen to stacked domains") but we somehow missed omap4 at that
point.
