The ROHM bd71837/47 (which is included in this series) as well as for 
the ROHM bd71815, bd71828, bd9576 and bd9573 (which are included in the 
other series) - there should be no PMIC internal dependencies to 
regulators. So, from my perspective this looks good.

Right after saying this - I don't have access to most of the boards 
using these PMICs - nor do I know what kind of system level issues there 
may be - hence my ack is not really worth much - but at least I can say: 
"Yes, bring em on - I am mentally prepared for the bug reports" :)

Thanks!

Yours,
	-- Matti
