Split the binding document to two separate documents (own for BD71837 and BD71847) as they have different amount of regulators. This way we can better enforce the node name check for regulators. ROHM is also providing BD71850 - which is almost identical to BD71847 - main difference is some initial regulator states. The BD71850 can be driven by same driver and it has same buck/LDO setup as BD71847 - add it to BD71847 binding document and introduce compatible for it. Signed-off-by: Matti Vaittinen --- Oh dear how bad I am with yaml... Lee, I think the support series for BD71828 included some changes to drivers/mfd/rohm-bd718x7.c - I will add BD71850 compatible to next version of that series in order to avoid conflicts.
