Subject[PATCH] regulator: max77802: Add input supply properties to DT binding doc
Message-ID<qgfyO-2sl-13@gated-at.bofh.it>
The max77802 regulator driver defines the supply name for each regulator
so these can be described in DT but is not mentioned in the binding doc.

regulators is still a node, so you should have 2 sections.

You are right, I included both because I saw other DT bindings doing
this but agree the correct approach is to have two separate sections.

Mark already applied this patch though so I can't send a v2 but I'll
post an incremental patch on top of his topic/max77802 branch:

https://git.kernel.org/cgit/linux/kernel/git/broonie/regulator.git/log/?h=topic/max77802
