Some of the PMIC's could have specific regmap configuration tables in future, so add specific compatible strings for known PMIC's. Also print runtime detected chip revision information. Signed-off-by:

gpio_defaults needs to be specified as an unsigned int rather than an int, because the intention of the DT binding is that all out of range values for a 16-bit register will cause the defaults to be used, however, if gpio_defaults is an int then values that are larger than INT_MAX will become negative numbers and be written out directly to the hardware. As no where in the code replies on gpio_defaults being an int, the simplest fix is to just change it to unsigned. Signed-off-by:

Since commit 6e3f62f0 ("mfd: core: Fix platform-device id generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when registering mfd-devices. Unfortunately, some mfd-drivers rely on the old behaviour of generating platform-device ids by adding the cell id also to the special value of PLATFORM_DEVID_NONE. The resulting platform ids are not only used to generate device-unique names, but are also used instead of the cell id to identify cells when probing subdevices. These drivers should be updated to use PLATFORM_DEVID_AUTO, which would also allow more than one device to be registered without resorting to hacks (see for example wm831x), but lets fix the regression first by partially reverting the above mentioned commit with respect to PLATFORM_DEVID_NONE.

Converting milliseconds to jiffies by "val * HZ / 1000" is technically OK but msecs_to_jiffies(val) is the cleaner solution and handles all corner cases correctly. This is a minor API consolidation only and should make things more readable. Signed-off-by:

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Signed-off-by:

Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck. So let's disable this function. Signed-off-by:
