Subject: [PATCH] dt-bindings: iio: adi,ltc2983: Fix 64-bit property sizes

The '/bits/ 64' notation applies the next <> list of values. Another <> list
is encoded as 32-bits by default. IOW, each <> list needs to be preceeded
with '/bits/ 64'.

While the dts format allows this, as a rule we don't mix sizes for DT
properties since all size information is lost in the dtb file.

Hi Rob,

Do you want me to pick these up, or as they are fixes would you rather take
them yourself to get them in quickly?

In case you want to pick this up.
