Subject: [PATCH 3/4] dt-bindings: nvmem: Allow bit offsets greater than a byte
Date:   Sun, 14 Aug 2022 12:36:54 -0500

Some NVMEM devices contain cells which do not start at a multiple of the
device's stride. However, the "reg" property of a cell must be aligned
to its provider device's stride.

These cells can be represented in the DT using the "bits" property if
that property allows offsets up to the full stride. 63 is chosen
assuming that NVMEM devices will not have strides larger than 8 bytes.
