There are a lot of similar global registers being used across multiple SoCs
from Unisoc. But most of these registers are assigned with different offset
for different SoCs. It is hard to handle all of them in an all-in-one
kernel image.
Add a helper function to get regmap with arguments where we could put some
extra information such as the offset value.

Add the cros-usbpd-notify driver as a subdevice on platforms that
support the EC_FEATURE_USB_PD EC feature flag and don't have the
ACPI PD notification device defined.
This driver allows other cros-ec devices to receive PD event
notifications from the Chrome OS Embedded Controller (EC) via a
notification chain.

The watchdog driver compatible is "dlg,da9062-watchdog" and not
"dlg,da9062-wdt". Therefore the mfd-core can't populate the of_node and
fwnode. As result the watchdog driver can't parse the devicetree.

Both manual and power on resets have a brief period where the chip will
not be accessible immediately afterwards. Extend the time allowed for
this from a minimum of 1mS to 2mS based on newer evaluation of the
hardware and ensure this reset happens in all reset conditions. Whilst
making the change also remove the redundant NULL checks in the reset
functions as the GPIO functions already check for this.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
name.
"SAMSUNG" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.
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/).

MAX77650 MFD driver uses regmap_irq API but doesn't select the required
REGMAP_IRQ option in Kconfig. This can cause the following build error
if regmap irq is not enabled implicitly by someone else:
ld: drivers/mfd/max77650.o: in function `max77650_i2c_probe':
max77650.c:(.text+0xcb): undefined reference to `devm_regmap_add_irq_chip'
ld: max77650.c:(.text+0xdb): undefined reference to `regmap_irq_get_domain'

On AXP288 and newer PMICs, bit 7 of AXP20X_VBUS_IPSOUT_MGMT can be set
to prevent using the VBUS input. However, when the VBUS unplugged and
plugged back in, the bit automatically resets to zero.
We need to set the register as volatile to prevent regmap from caching
that bit. Otherwise, regcache will think the bit is already set and not
write the register.

AB8505 support was never fully converted to the device tree.
Most of the MFD cells for AB8505 lack an "of_compatible",
which prevents them from being configured through the device tree.
Align the definition of the AB8505 MFD cells with the ones for AB8500,
and add device tree compatibles. Except for GPIO and regulators the
compatibles are equal to those used for AB8500 because the hardware
does not differ much.
Finally, change db8500_prcmu_register_ab8500() to check for the AB8505
device tree node additionally, and probe it if it is found.

The configuration is almost identical to AB8500, so just add a note
for the nodes/compatibles that differ between the two revisions.
