arm64: dts: freescale: imx8mm-verdin: enable hysteresis on slow input pin

[ Upstream commit 67cc6125fb39902169707cb6277f010e56d4a40a ]

SODIMM 17 can be used as an edge triggered interrupt supplied from an
off board source.

Enable hysteresis on the pinmuxing to increase immunity against noise
on the signal.

Disable usb over-current of the chipidea driver on all Carrier-Boards

Remove the now obsolete disable-over-current flag from module-level
device-tree imx8mm-verdin.dtsi and leave it as already mentioned to
the people actually implementing the carrier-board to implement this.

This will prevent the warning "No over current polarity defined" from

arm64: dts: imx8mm-verdin: extend pmic voltages

Currently, we limited the voltages from the PMIC very strictly. This
causes an issue with one Toradex SKU that uses a consumer-grade chip
that is capable of going up to 1.8GHz at 1.00V.

Extend the ranges to min/max values of the SoC operating ranges (table
10) in the datasheet. Detailed explanation as follows:

BUCK2:
- As already described above, the SKU with the consumer-grade chip
needs a voltage of at least 1.00V. 1.05V is chosen now as this is
listed as the maximum. Both industrial and consumer-grade chips have
an absolute maximum rating of 1.15V which makes it still safe to put
1.05V
- Lower the regulator-min value to the smallest value allowed from the
Quad-A53, 1.2GHz version of the SoC

BUCK3:
- This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and
VDD_DRAM.
- Use the smallest value of these three inputs as the regulator-min
- Use the largest value of these three inputs as the regulator-max

LDO2:
- This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a
single nominal input voltage just put this in the middle of 0.8V.

arm64: dts: verdin-imx8mm: add otg2 pd to usbphy

The Verdin iMX8M Mini System on Module does not have USB-ID signal
connected on Verdin USB_2 (usbotg2). On Verdin Development board this is
no problem, as we have connected a USB-Hub that is always connected.

However, if Verdin USB_2 is desired to be used as a single USB-Host port
the chipidea driver does not detect if a USB device is plugged into this
port, due to runtime pm shutting down the PHY.

Add the power-domain &pgc_otg2 to &usbphynop2 in order to detect
plugging events and enumerate the usb device.
