    Merge series "Support ROHM BD9576MUF and BD9573MUF PMICs" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
    
    Initial support for ROHM BD9576MUF and BD9573MUF PMICs.
    
    These PMICs are primarily intended to be used to power the R-Car family
    processors. BD9576MUF includes some additional safety features the
    BD9573MUF does not have. This initial version of drivers does not
    utilize these features and for now the SW behaviour is identical.
    
    Please note that this version of drivers is only tested on BD9576MUF
    but according to the data-sheets the relevant parts of registers should
    be same so drivers should also work on BD9573MUF.
    
    This patch series includes MFD, watchdog and regulator drivers with
    basic functionality such as:
    
    - Enabling and pinging the watchdog
    - configuring watchog timeout / window from device-tree
    - reading regulator states/voltages
    - enabling/disabling VOUT1 (VD50) when control mode B is used.
    
    This patch series does not bring interrupt support. BD9576MUF and BD9573MUF
    are designed to keep the IRQ line low for whole duration of error
    condition. IRQ can't be 'acked'. So proper IRQ support would require
    some IRQ limiter implementation (delayed unmask?) in order to not hog
    the CPU.
