Subject: [PATCH 0/9] Drop ROHM BD70528 support

Drop ROHM BD70528 support

Unfortunately there has not been a big demand for ROHM BD70528
IC. The few users I know control PMIC from separate M4-core,
which is not running Linux. I am not aware of any users of this
Linux driver.

While I did really like this IC and writing the drivers for it,
seems like these drivers are becoming useless burden. So, I see
no point in maintaining them. Let's just drop the drivers if
there is no objections to this series. :(

Few notes:

The GPIO, regulator, power-supply and watchdog drivers should be
only used on BD70528 and depend on the BD70528 MFD Kconfig. I guess
the removal can be independently merged to the respective subsystems.

The BD70528 RTC driver is still used by BD71815 and BD71828 -
but the watchdog-hack can be removed and driver is greatly
simplified. However, it's worth noting that there is dependency
from the BD70528 RTC driver to the header files - thus the
RTC driver changes should be merged before MFD changes. Also the
CLK driver remains in use and needs the BD70528 IC-type.

As a final note - Few improvements/fixes were just applied to the
regulator tree so this series is likely to conflict. Some fixes
were also added to RTC Kconfig - which means also the RTC tree
may have conflicts. Please let me know if you wish me to rebase
this series or those patches.
