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. Signed-off-by:

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. Signed-off-by:

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.

States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages.
