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/).

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.

ROHM BD71828 PMIC contains 4 pins which can be configured by OTP to be used for general purposes. First 3 can be used as outputs and 4.th pin can be used as input. Allow them to be controlled via GPIO framework. The driver assumes all of the pins are configured as GPIOs and trusts that the reserved pins in other OTP configurations are excluded from control using "gpio-reserved-ranges" device tree property (or left untouched by GPIO users). Typical use for 4.th pin (input) is to use it as HALL sensor input so that this pin state is toggled when HALL sensor detects LID position change (from close to open or open to close). PMIC HW implements some extra logic which allows PMIC to power-up the system when this pin is toggled. Please see the data sheet for details of GPIO options which can be selected by OTP settings.

Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages. The parsing functions can be re-used by other ROHM chip drivers like bd71828. Split the generic functions from bd718x7-regulator.c to rohm-regulator.c and export them for other modules to use.

ROHM BD71850 PMIC is almost identical to BD71847. Main difference is some initial voltage values for regulators.
